What is secondary glazing?

| 22.12.23

Secondary glazing can provide a cost-effective and efficient way of improving the heat retention, sound reduction and security of your windows.

Secondary glazing involves installing a “secondary” window, i.e. a fully independent internal window, on the room side of your existing primary window.

Fitting an internal secondary window forms double glazing with your existing single glazed window. The secondary window is a separate unit consisting of a single glazed pane within its own frame and is fitted on the room side of your existing windows and sealed around the edges.

The range of secondary windows includes horizontal sliders, vertical sliders, top hung, side hung, double side hung, lift-outs, and removable fixed panels fitted onto the back of doors.

What are the benefits of secondary glazing?

Secondary glazing is a cost-effective way of improving heat retention and sound reduction in your home, as well as providing some additional security.

It can be a great less expensive alternative to replacing double or triple glazed primary windows.

Secondary windows units usually have separate handles and open so that you can get access to clean and open your primary windows.

Secondary glazing can result in significant cost savings

Secondary glazing is considerably cheaper and easier to fit than replacement windows because it doesn’t require complete removal and replacement of your existing windows.

Heat loss is reduced with secondary glazing

A major long-term benefit of secondary glazing is heat retention properties. This is because it adds a second layer of glass behind your existing primary windows that reduce both the amount of warm air that can escape from your home and the amount of cold air that can enter.

The heat generated from your heating system will remain inside rather than escaping through inefficient windows, and there will be fewer draughts, making you feel warmer. Your heating bills could drop substantially as your home becomes more energy efficient, great for you and great for the environment.

Experience less external noise with secondary glazing

Secondary glazing also acts as an extra physical barrier against outside noise, reducing the amount of sound coming into your home through (closed) windows.

This noise reduction can be further improved by installing special sound-reducing laminate glass, or by having a gap of at least 100 mm between the secondary and primary window and lining the window head and reveals in between with acoustic tiles.

Extra protection for your existing windows

Secondary glazing means your existing primary windows do not need to be removed, and there are many reasons why you might need to retain your original windows.

This is particularly useful in listed buildings, buildings in areas where they are subject to an Article 4 Directive, and areas where planning permission rules do not allow any aesthetic changes whatsoever to the external primary windows.

These older properties are often draughty and adding secondary glazing that doesn’t require any planning permission may be the only effective way to reduce heat loss and improve sound insulation.

In other circumstances where windows cannot be replaced or where you don’t have the budget to replace them, secondary glazing can provide an alternative solution. It’s also a great cost-effective option for rented accommodation.

Secondary glazing is low maintenance

Secondary glazing is low maintenance and doesn’t cause the same level of disruption as fitting replacement primary double or triple glazed windows, and can last for many years.

All About Secondary Glazing

| 14.09.20

Following the Government’s inclusion of secondary glazing in the Green Homes Grant Scheme (launched 1^st September), there have been many queries made to MyGlazing.com and the Glass and Glazing Federation (GGF) about the performance and qualities of Secondary Glazing.

Here’s the responses from the MyGlazing.com team in conjunction with the Glass and Glazing Federation and GGF Members Pilkington UK and Roseview Windows.

How does secondary glazing compare to replacing with windows for new double or triple glazing in terms of improving energy efficiency?

Secondary glazing when placed in close proximity to a primary window can offer good thermal improvements and increase your energy efficiency. If you live in a listed buildings often local council restrictions means that you can’t replace the original window design (and specification which is usually single glazed) with double or triple glazing so secondary glazing units can be a good alternative.

The energy efficiency performance is not as high as that of a full double or triple glazing replacement, mainly because of the huge advance in the quality of sealed insulating double and triple glazed windows and doors, however, secondary glazing can still be an effective solution.

One the most common ways of determining thermal performance in building materials is the U value, which measures how easily heat can pass through a material. Materials that allow more heat to escape from a building have higher (i.e. worse) U-values. Materials that let less heat pass through them have lower (i.e. better) U-values.

Solely based on glass U-values the table below is a reasonable measure of the difference on different window types:

Glass type	U value (W/m²K)
Single pane	5.7 to 5.8
Single pane with secondary glazing (with 150mm air gap)	2.9
Single pane with Pilkington K Glass^TM coated secondary glazing (with typical 150mm air gap)	2.0
Replacement double glazing unit with low E coating	1.0 – 1.5
Single pane with secondary glazing, glazed with double glazing slim unit with low E coating (not often used as cost is similar to standard double glazing)	0.9
Replacement triple glazing unit with two panes with low E coating	0.5 – 0.8

The above table does not include the individual performance of frames, seals and insulation around the frames, the U values of the glass are based on typical performances.

Low emissivity (low E) coatings are microscopically thin, transparent coatings (much thinner than a human hair) that reflect long-wave infrared energy (or heat). So instead of heat escaping through the glass, a low E coating will reflect heat back into the home. In secondary glazing hard coat Pilkington K Glass™ is used to create the same effect.

The table shows the difference in thermal insulation from a single pane of glass through to a triple glazing unit with two panes of low E glass. As you can see the difference from single glazing with the addition of secondary glazing approximately doubles energy efficiency.

Many homeowners living in conservation areas and/or listed buildings who may be restricted by local authorities on installing modern home improvements, use secondary glazing as a solution to improve energy efficiency because once installed, it improves energy bills immediately. However, it is worth noting that installing double glazing or triple glazing does increase thermal performance even more significantly, by roughly 100% from secondary glazing.

Secondary glazing can also effectively eliminate the draughts commonly found with old single glazed windows. Draughts aren’t directly measured by U value but they can of course adversely affect a building’s energy efficiency and the occupant’s comfort levels.

Being a less expensive option (approximately 50% less on a supply and install) Secondary glazing is often an easier or temporary solution for those homeowners who want to improve their energy efficiency but may not have a huge budget.

What is the average cost of secondary glazing?

Cost varies depending on the specification. Secondary glazing can be bespoke, coloured and shaped to suit the period properties they are found in. Designed to cover the existing window style and be hardly visible, the variation in styles these days includes fully tilt out to clean units. On average, a typical secondary glazing window/unit is around half the price of a double glazing window. The installation of secondary glazing is also better for acoustics, whether it’s keeping sound out or in.

When would it be beneficial to use secondary glazing over replacement windows?

Noise prevention is one of the main benefits. Secondary glazing is used extensively throughout the country to combat noise pollution. It is often fully subsidised as part of government schemes to improve living conditions in particular situations such as airport flight paths and housing in proximity of railways or highways. The noise cancelling effects of secondary glazing are particularly impressive.

Secondly in conservation areas or listed buildings where restrictions are in place. Many older public buildings like museums, schools or town halls have secondary glazing installed because the owners or local councils may have to retain the external appearance of the building. Professionally installed secondary glazing is virtually invisible from the exterior of such a property and delivers the advantages of energy efficiency and noise reduction.

Secondary glazing also offers an added layer of security and the internal finishes that can be achieved with secondary glazing are now of such a high quality, they can be a real feature of the interior design.

What are the drawbacks of secondary glazing?

Secondary glazing is not as energy efficient as a new double or triple glazing windows, though it does improve energy efficiency where there are local council restrictions. One drawback that is sometimes mentioned is the maintenance and cleaning of secondary glazing. It can mean twice as much work when cleaning, especially when double and triple glazing can also feature self-cleaning glass. However, most modern secondary glazing panels are removable and the weight of a single glazed panel is much lighter to handle when doing so.

It has been mentioned that in some situations, secondary glazing can resolve a problem with condensation. Providing an extra barrier of glass can help regulate the extreme temperature clash of cold glass pane against warm centrally heated air though it should always be well ventilated to reduce the likelihood of condensation. Secondary glazing is not the best energy efficient glazing solution, because the seals are not as airtight as those on double and triple glazing. In addition, the thermal performance of secondary glazing is very much dependent on the condition of the prime single glazed window on a building’s exterior.

Can’t replace your windows? Try secondary glazing

| 03.02.17

A case study shows that where installing new energy efficient windows is not an option, secondary glazing can provide many of the same benefits

Installing energy efficient glazing can help make your home warmer, quieter and more comfortable to live in – and help lower your heating bills.

However replacing your old windows may not always be an option. Whether your budget doesn’t stretch that far or it is impractical or impossible (due to planning restrictions) to replace your current glazing, that doesn’t mean you can’t take action to reduce the heat lost through your windows and enjoy all the resulting benefits.

MyGlazing.com has drawn a case study from GGF Member company Selectaglaze to show how you can overcome the problem when you can’t replace your existing windows or doors.

Case study: Brighton’s historic Ship St Post Office

One reason window replacement may not be an option is when the property in question is a Listed or Historic building.

That was the case with Brighton’s historic Ship St Post Office building, the city’s main post office for many years. Dating back to 1925, and incorporating parts of an earlier building dated 1898, it was recently renovated with the aim of transforming it into comfortable apartments.

However creating warm living spaces turned out to be quite a challenge. The primary windows were draughty, allowing heat to escape and due to the listed nature of the building they could not be changed.

For many homeowners living in heritage or listed properties this can be the reality. Luckily it needn’t be a deterrent.

Secondary glazing solution

In this case, secondary glazing provided the ideal solution. A separate window fitted inside the existing primary window, it traps an insulating layer of air which can reduce heat loss by up to 50%.

Secondary glazing is fitted to the room side of the building and is fully reversible, making it a popular choice for heritage properties.

As well as improving the thermal efficiency of windows, secondary glazing can help reduce the amount of noise that enters a property through closed windows.

GGF Member company Selectaglaze installed 75 vertical sliding units at the Ship St address. All units are bespoke to ensure the tightest fit with matching sight lines where possible, to make them virtually unnoticeable from the outside.

Glazing and noise reduction in homes

| 22.12.23

Replacing or upgrading your windows can improve noise reduction in the home.

What is noise?

Noise is unwanted sound. In the home, this is any sound that distracts or disturbs the occupants.

This could be anything from nearby traffic or low flying aircraft to sounds coming from neighbouring properties such as music and loud conversation.

How it travels

Sound travels through the air (and solids and liquids) like the ripples seen on the surface of a pond when you throw a stone into it. Just like these ripples, the waves decrease in intensity as they move away from the source.

Sound intensity is measured in decibels (dB). A low dB value indicates a soft sound and a high dB value a loud sound.

How it affects us

The perception of noise will vary from person to person depending upon the source of the noise and the individual’s tolerance/acceptance of a given type of noise.

For example, a person living next to a busy road for a number of years may have become accustomed to it, whereas someone relocating from a quiet location to the same busy road may find the noise a nuisance.

How glazing can help reduce noise

One of the many potential benefits of replacing windows or installing secondary glazing in your home is that in doing so you can often also improve your property’s noise insulation.

The correct installation of good quality, well-made windows or secondary glazing systems can result in a noticeable reduction in noise levels.

Type of glass

The type of glass used within your replacement window could have an effect on the level of noise reduction. Glass is available in a range of thicknesses and typically thicker glasses reduce more noise.

Domestic windows usually use 4mm-6mm thick glass. Some window panes are made up of two or more pieces of glass that have been bonded together; these are known as laminates. Specialist, acoustic laminated glass is available from many glass manufacturers.

Thickness of glass

Different thicknesses of glass are effective at reducing noise at different frequencies. As a result, a sealed double or triple glazed unit with glass panes of different thicknesses (i.e. both 4mm and 6mm) will be effective at reducing noise across a wider range of frequencies than if both panes of glass were the same thickness.

Triple glazing

In addition to reduced thermal losses, triple glazed units can provide a reduction in noise. By increasing the combined thickness of the glass within the unit, the mass is increased. A reduction in noise transmission will result from this additional mass.

Air gap

The size of the air gap between the panes of glass in either a double or triple glazed window or a secondary glazing system makes a significant difference to the level of noise insulation. Typically a large air gap will improve noise insulation.

Secondary glazing

Secondary glazing is when another window or glazed screen is positioned within the window reveal of an existing window.

The extra glass pane and air gap now present in the window unit help to improve its noise insulation properties. In some cases, noise reduction can be further improved by lining the window reveal with sound insulation material.

The effect of ventilation and air gaps on noise reduction

To be effective in reducing noise new windows and secondary glazing systems must be fitted and sealed correctly. Any air gaps around your window will seriously affect its noise reduction properties.

It is also important that any opening window can be securely closed with a good quality seal. If the window does not close correctly noise will be able to infiltrate the property.

Bear in mind that many windows are designed to provide your property with a means of ventilation. Background ventilation through trickle ventilators can, if left in the open position, provide a passage for sound to travel.

Likewise, an open window, perhaps in the night lock position, will not aid sound reduction.

Glazing may only be part of the solution

Replacing or upgrading the glazed elements of a home may not singlehandedly solve the problem of excessive noise levels.

This is because noise entering the home via roofs, walls and floors will not be reduced as a result of changes to glazing. Depending upon the source of the noise and type of property, replacing or upgrading the glazing may only be part of the solution.

It is important to discuss your requirements and your expectations with the window installation company.

By explaining the source of noise that you are trying to reduce, the glazing company can advise you on what can be achieved.

The dB reductions possible using the various methods can be supplied by your glazing contractor. Any claim of noise reduction should be backed up by test evidence.

GGF Members will be able to advise you on the most suitable glazing option to reduce noise in your home – find a local GGF Member company.

Green Homes Grant Scheme and your glazing

| 30.09.20

The Government has now launched a new scheme to improve the energy efficiency in domestic homes, but what does it mean for your glazing.

If you are upgrading your home and thinking about installing double or triple glazing then you may be disappointed with the Green Homes Grant Scheme, because to upgrade you need to have single glazing already in place. If your windows are double glazed then you will not qualify for an upgrade under the new scheme.

Here’s the information on the scheme as well as the best advice for your glazing home improvement.

What does the Green Home Grant Scheme Cover?

A maximum grant of £5,000 covers up to two-thirds of the cost of some of the energy-efficient improvements you can make in your home. The improvements you can make using the grant are split into two categories – primary measures and secondary measures.

The primary measures cover loft, wall and floor insulation as well as thermal systems and ground or air source heat pumps.

If you already have these features, you can apply for grant money to improve them and if you do this, you can then claim funding for secondary measures which means you can upgrade your single glazing with double or triple glazing, or secondary glazing.

Worth noting that you cannot get more money for secondary features than you can for primary. For example, if you got £1,000 for insulating a loft and installing a solar thermal system, you could not get more than £1,000 for putting in double glazing to replace your single glazing.

Are you eligible?

The scheme is expected to help 600,000 homeowners to make properties more energy efficient.

If you live in a home you own, the scheme includes long-leaseholders and homes with shared ownership.

If you are a landlord and rent out privately or for social rent you are also eligible, while park homeowners, including traveller sites, also qualify for the scheme, though new-build homes are not eligible.

If you own your own home and are on Government benefits like Jobseeker’s Allowance you could be eligible for a bigger grant of up to £10,000 for the improvements – covering the entire cost of the refurbishments.

How to apply?

The Government will later in August provide advice to homeowners on how to apply from the Simple Energy Advice (SEA) website which will tell you in greater detail what areas of your property may be eligible for funding.

A list of government-accredited builders and tradespeople will also be available to choose from when the scheme is launched. Once the work is agreed, the Government will issue vouchers from the end of September.

Best Advice

Replacing Double Glazing

If you are planning on replacing or are replacing your existing double glazing, then don’t delay the job and use a GGF Member (listed in the MyGlazing.com installer search directory), to undertake the work. Only single glazing is available under the scheme.

If you have leaky or pre-2002 inefficient double glazing but you do qualify for the primary measures under the scheme and are installing insulation (primary measures), then it is worth considering replacing your double glazing over and above the scheme to complete your upgrade and make your home truly energy efficient. Remember up to 24% of heat energy can leave a house through inefficient windows.

Replacing Doors

The Government has yet to issue full details of door replacement and what will qualify under the scheme. However it will be a secondary measure.

Installing a conservatory or orangery

Conservatories, orangeries and garden rooms are not include under the scheme.

The Scheme is launched in September, but it is estimated that vouchers will be issued at the earliest at the end of September. Replacing single glazing with double/triple or secondary glazing is a secondary measure and not guaranteed unless you install or upgrade other measures. It’s also worth getting your home improvement done before the winter sets in, so our advice is, don’t rely on the Green Homes Grant Scheme but if you feel it’s worth the wait and you are sure you can upgrade your single glazing then it may be worth getting your application in when the scheme is launched in September.

When to repair or replace your windows

| 22.12.23

Repairing or replacing windows – there’s a lot to consider, including the benefits of upgrading to energy efficient glazing. Here’s some advice to help you decide.

The decision about whether to repair or replace windows can be challenging. Just like any home improvement, it is important to think about costs and potential savings in the short term as well as over a longer period.

This is especially pertinent for glazing in the home because upgrading to windows with a higher energy efficiency rating has the potential to reduce your annual household energy use.

So when considering window repair or replacement it can be helpful to bear in mind the potential savings you could gain by installing windows with a higher level of energy efficiency.

Window maintenance and identifying problems

The importance of properly maintaining the windows in your home cannot be overstated. That’s because in addition to potentially affecting the value of your property, the condition of your windows can have a significant effect on both how comfortable your home is to live in and how much energy is required to heat and cool your living areas.

To help identify problems with your windows and the best course of action to take, we have provided some expert guidance in four easy steps.

Step 1: Visually inspect both sides of the windows

Inspect your windows for any evidence of rot (timber windows) or other damage to the hinges or jambs (the vertical parts that form the side of a window frame). Check if any of the seals are damaged, and if there are any chips in or around the glass.

Windows can be damaged by the sun, water and other weather exposure, so check for signs of this. If your windows have any of these faults which are compromising their performance or aesthetic looks (or both), you may wish to consider getting them repaired before any further damage occurs.

Step 2: Test the performance of your windows

Can you open and close your windows? Sounds obvious but sometimes windows stick due to paint, heat expansion or a broken handle. Also, check if there are any noticeable draughts. All of these are signs your windows may need repairing.

On rare occasions you may see condensation between the panes of a glass sealed unit where the seal of the sealed unit have failed. If so, the sealed unit will need to be replaced and this can usually be done quite easily by your window repair company, although they will have to take exact measurements to order a sealed unit specific to size.

Step 3: Analyse the impact on your living environment

Energy efficiency

Window quality may well be affecting your heating bills. If you have single glazed windows, then it could make a tremendous difference to the comfort of your home and your heating bills if you were to replace them with energy efficient double or triple glazed windows. New energy efficient glazing has the ability to reflect heat back into the room due to a low-emissivity (“Low E”) coating which has the effect of reducing heat loss through the windows.

Instead of replacing your windows, a less expensive option to improve energy efficiency would be to consider installing secondary glazing inside your existing windows, to form “double glazing”, however your existing windows must be in excellent condition.

Noise reduction

Are you affected by noise? If you live near noisy roads or other types of noise disturbance, then you can improve your living comfort by replacing windows to double or triple glazing that can reduce the passage of sound. Glass sealed units with enhanced acoustic options are available to reduce the noise further.

Again, if you wish to reduce noise and keep your existing windows, installing secondary glazing is a less expensive option. And for noise reduction, the bigger the gap between your existing windows and the secondary glazing the better. The head and jambs of the windows within that gap can then be lined with acoustic material if desired to further reduce the noise levels.

Ventilation

It is important to ensure that adequate ventilation is maintained when replacing your windows. This will allow for good air flow and reduce the risk of condensation on the inside of the windows.

Step 4: Consider the age of your home

Older homes – It‘s hard to decide if you should replace windows when they are original features of the house. If your home has stained or leaded glass, then replacing them could reduce the value of your home.

However, the good news is that these days window manufacturers can replicate your stained or leaded glass in energy efficient replacement windows.

If you have a home which is centuries old and listed, then you will need to obtain permission from your local planning officer for any changes. There are specialist glass suppliers who can locate such replicas of centuries-old glass if pieces are damaged.

Similarly, if your home is in an area covered by an “Article 4 Direction”, then you will need to obtain permission from your local planning officer for any changes. Homes in Conservation areas have permitted development rights and do not need planning permission to change windows, so long as the replacement windows are of similar aesthetics to your existing ones.

Still unsure? Contact a glazing professional

If you are unsure about whether to repair or replace windows in your home, it’s a good idea to talk to a glazing professional who can advise you on your options and provide quotes if necessary. Find your nearest GGF Member company.

Is your home ready for winter?

| 11.11.16

Your home is your sanctuary – and keeping it warm can be a challenge. Here are some tips on making your home more energy efficient and keeping the heat in and the cold out.

As the temperature dips, the leaves fall and Christmas lights go up, don’t forget to get your home ready for the cold winter months.

Here are some helpful tips to get your home winter ready.

1) Keep the warmth in (and the cold out)

First off be sure to check that your heating system is in good working order.

Next, make sure that once heat is generated it doesn’t get lost straight away. Check the seals on your windows and doors and if they are broken, we recommend you have these repaired as soon as possible.

A lot of heat can be lost through single glazing and even double-glazed windows installed before 2006. If you believe this is happening in your home, contact a glazing professional to discuss installing or replacing your old windows with modern thermally efficient glazing. Secondary glazing and/or applied window film should also be considered as an option.

It is important to ensure your home has sufficient ventilation to keep living areas healthy and prevent the build-up of moisture. Without adequate ventilation, moisture in the air may lead to condensation, which can cause mould on walls and damp that can damage interior surfaces and impair the quality of vision of your windows.

2) Keep energy use under control

It’s normal for fuel bills to rise over the winter, but that doesn’t mean you can’t find ways to reduce your energy use at this time of year.

Your home’s windows could be a potential energy saver. If you live in a semi-detached house with single glazed timber windows and electric heating, upgrading to A+ rated energy efficient windows could potentially save you up to £446 a year in energy costs, based on the average window area for this home type.

Find out how much you could potentially save: GGF Energy Savings Calculator

3) Prepare your home’s exterior

Winter can bring all sorts of extreme weather to your doorstep, so preparing the exterior of your home for what nature could throw its way is a good idea.

– clear out gutters and downpipes.

– check roof tiles and rooflights and have leaks repaired now before the worst of the weather arrives

– check the exterior of all windows and doors for damage that needs repairing

Why shiver this winter? Prepare your home, stay warm and think about the measures you can take to improve your energy efficiency.

Stevenage Glass celebrates 50th anniversary

| 25.08.16

GGF Member company Stevenage Glass recently marked a major milestone – half a century in the glass and glazing sector operating in Stevenage, St Albans and beyond.

Reaching your 50th anniversary is a notable achievement for any company, and in light of this, Stevenage Glass is using this momentous year to blend the old with the new to show just how far they’ve come since 1966.

Owner and managing director Kim King commented:

“Throughout the last 50 years, we’ve seen many changes as the company has flourished and expanded, including moving to larger premises on Cavendish Road after we outgrew our starter premises on Argyle Way, and we haven’t looked back since! Even after the move, we’ve already made a couple of extensions to keep up with the demands of the growth of our business even more.”

Stevenage Glass began to extend their product range further to better accommodate for the needs of their ever-growing customer base, with their range now including a wide selection of glass products for interior home improvement for bathrooms, kitchens and living areas.

These new additions complement their core services, such as emergency glazing, secondary glazing, window repair and glass cutting, all of which have grown and developed over the last five decades.

Proud GGF Members

As a founding member of the Glass and Glazing Federation (GGF), Stevenage Glass offer an impeccable standard of work, consistently meeting all industry standards across the board, and their affiliation with GGF further serves as an example of their commitment to the industry and the standard of work they do.

Nigel Rees, GGF Chief Executive, commented:

“Congratulations to Stevenage Glass on their 50^th Anniversary. They have been with the GGF since the very beginning of the Federation and their attention to high quality and service has obviously been an integral part of their success. This year is a special year for all at the company and the GGF wishes them all the best with their celebrations.”

New branding launched

Part of Stevenage’s celebrations include the launch of updated branding. As a testament to the company’s hard work and the quality of their products and services that have carried them through the last five decades, the company worked with fellow GGF Member Adtrak Ltd to create a style that celebrated their past and incorporated a glass element to symbolise their expertise in the product.

Stevenage Glass decided to resist the temptation to modernise as much as possible to make the brand feel completely new, feeling that this would be missing the point – after all, reaching their 50th anniversary is an impressive achievement! And here is the finished product:

The final look is minimal and modern while also echoing the way things used to be, combining a new, technologically advanced feel with the timeless quality of an old, experienced business. Simple lines are used to make glass pane-like shapes, and a light, understated colour scheme creates a theme that runs throughout the company’s branding.

Looking ahead to the next 50 years

Owner Kim King spoke on the company’s future:

“After an extremely successful first 50 years, Stevenage Glass is setting the bar high to make the next 50 even better with further progression and plans for the future – so watch this space!

One thing is for sure: we will always remain Stevenage’s original glass manufacturers and heritage glaziers. On behalf of the company I’d like to say a huge thank you to all of our staff and customers who have remained loyal and supported us throughout the years; we wouldn’t be here celebrating our success today if it weren’t for you!”

We’re sure that over the years you’ll be hearing more about the brand, as well as more about how they got to become one of the industry’s leading experts.
