Touchstone Glazing Solutions Ltd

|

With over 25 years worth of experience in the traditional leaded light industry, we developed Touchstone Insulead glazing system (Patented) to specifically overcome the problem of double glazing windows in a heritage building situation. No modification to the existing fabric of the building is required as the Insulead glazing fits where the original was located, and is made using only traditional materials.

Directly glazed into the original stonework

An appearance virtually identical to the original

Touchstone Steelyte opening casements are uniquely designed and constructed from Stainless Steel. Thermally broken and fully weather stripped, they take a full 28mm unit. They combine the narrowest of sight lines with security, durability and elegance. The steel is all but immune from corrosion. Whilst powder coated for the heritage market openers can be supplied polished for modern building applications.

Stainless steel and effectively maintenance free

Due to Touchstone Insulead’s unique ability to take any thickness of unit (28mm standard) it is possible to incorporate specialised glass for the purposes of security, UV filtration, energy conservation and sound inhibition all whilst maintaining a traditional appearance. It is even possible to use the original glazing either within the double glazing or mounted in front or behind as a decorative screen.

Extensive range of glazing options including original

Shapes and out of square windows easily accommodated

Touchstone Insulead has been specifically designed for double glazed units. It is fully drained and thermally broken. In the unlikely event of water ingress through, for example stone porosity, the inbuilt drainage channels allow the water to exit to the outside via weep holes. Combined with warm edge spacer bar technology the highest level of insulation is possible.

Fully drained and thermally broken

  • Double Glazing for heritage buildings
  • Steelyte Stainless Steel Opening Casements
  • Insulead Patented Frameless Double Glazing
  • BFRC “A” Rated

When to repair or replace your windows

|

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.

Planning a conservatory – things to consider

|

Planning your conservatory

With a wide range of conservatory types available, careful thought and planning can help you decide on the one that fits best with your home and suits the needs of everyone who will be using it.

Once you’ve chosen a conservatory style, here are some more things to consider when planning your glazed home extension.

Size

When deciding on the size of your new conservatory, make sure you’ll have enough space to enjoy it. A handy tip is to mark out the planned dimensions in your living room so you can see how much furniture you’ll be able to fit.

Sunlight

How much direct sunlight will your conservatory receive and at what time of the day? This could have a bearing on your choice of building location and also interior design decisions.

The orientation of your conservatory may mean that certain specifications of glazing are more appropriate than others because of the impact of solar heat gain from the sun (see ‘Glazing’ below).

Materials – general

You can choose from a wide range of materials for your conservatory, not only for the frames but also in the glazing, the roof and any masonry.

Think about the mood and texture you want to achieve. Some people like the ‘outdoor’ feel with tiled floors, patio-type furniture and bare brick or stone for the house wall; others prefer an ‘indoor’ character with carpeting, soft furnishings and wall coverings.

Materials – frame

Aluminium, with thermal breaks for enhanced heat insulation, is a popular choice and is available in a range of colours and finishes.

PVC-U is the most popular frame material with its long life expectancy and minimal maintenance, especially as nowadays a range of wood grain-effect finishes combine the authentic look of wood with all the toughness of PVC-U.

Wood is the natural choice for people who insist on the real thing.

Glazing

Double glazing is a must nowadays to keep a conservatory comfortable all year round and by using low emissivity (Low-E) glass, it can cut heat loss even more.

If the conservatory is south or west facing it is advisable to consider the use of a modern solar control glass for the roof and side panels of the conservatory.

Solar control options range from ‘body tinted’ glass (where the colour in the glass absorbs heat from the sun) to ‘metallic coated’ glass products.

Modern metallic coated products have the advantage of being neutral in appearance, not obscuring views, while still reflecting the sun’s heat.

Roofing

There are two main choices of roofing – glass or polycarbonate.

Glass gives you a clear view through the roof – it can be supplied with solar control and self-cleaning coatings too. Laminated glass and safety filmed glass can add protection you from any falling debris on the roof glazing of your conservatory.

Polycarbonate creates a softer light effect in bright sun (however, it is slightly noisier in heavy rain or hail).

Ventilation

Ventilation is important. You need to be sure that your conservatory will let in fresh air and avoid condensation.

The internal environment can be carefully controlled with the correct specification of both materials and ventilation. Many roofs have built-in trickle ventilation and Building Regulations specify a certain area of opening windows per floor area.

Technological developments mean that you can have opening roof vents installed that can be thermostatically controlled with built-in rain sensors.

Sound control

Whether it be rain, music, lawn mower, traffic or aircraft noise, reducing the impact of environmental sound can enhance the enjoyment of your conservatory.

The use of laminated glass or enhanced acoustic insulation laminated glass can lessen the amount of noise transferring into or out of your conservatory.

In addition, laminated or acoustic laminated glasses have the extra benefit of reducing standard ultra-violet (UV) light transmission. This means sun bleaching of furniture or fittings is dramatically slowed.

Cleaning and maintenance

Consider what will be required to clean and maintain the glass throughout your conservatory.

Surface modified glass such as self-cleaning glass is available from many glazing companies and can reduce the need for cleaning the external window panes, particularly in difficult-to-reach roof areas.

Comfort and convenience

Comfort levels and environmental factors should be considered. You may wish to extend your home’s central heating, install a separate heater or go for an underfloor heating system, but remember careful specification, design of materials and the location of the conservatory itself can all lead to natural environmental control.

Similarly, you can have overhead wiring for lights built-in or simply a few wall sockets for a table lamp and other appliances.

The GGF Visits Number 10 Downing Street

Politics |

Yesterday, GGF President Natalie Little, Group Managing Director John Agnew, Head of Membership and Customer Relations Ben Wallace and Head of GGF Technical Department Dave Borland had the honour of attending Number 10 Downing Street to meet with Prime Minister Rishi Sunak’s Political Advisor, Ameet Jogia MBE.

We were able to discuss in detail the GGF x British Glass collaboration, A Window of Opportunity and how the document articulates a story to educate and inform Government, Treasury and Stakeholders about windows and doors and the contribution that they can make to energy efficiency.

John Agnew, Group Managing Director at the GGF, explains: “The GGF recently conducted a comprehensive piece of research into the part glazing can play in achieving Net Zero, and the results were conclusive. Despite the fact 86% of homes already have double glazing (the government’s previous argument for excluding the sector from the Energy Company Obligation (ECO+) Scheme), we all know that this isn’t the full story. For example, seventy per cent of windows installed since 2002 were C rated and so they don’t meet the relevant building standards of today.”

The GGF translated the research into the easy-to-read ‘A Window of Opportunity’ infographic to highlight the difference glazing can make.

GGF President, Natalie Little said: “Thank you to Arun Photay for facilitating the engagement and for his gracious hospitality. It was certainly a milestone for our industry and any progress that the GGF makes in the space is progress for all stakeholders in this industry.”

Natalie continues: “We successfully highlighted to government that the research calculates a significant 80 million windows would benefit from immediate replacement, saving as much C02 as taking 1.88 million cars off the road. We were also able to demonstrate the timely cost saving benefit to individuals as the research estimates the average annual saving per household for upgrading windows to current standards at £395.” The GGF will continue to support the industry by gathering and collating the facts and presenting them to the people that have the power to make a change.

It was a privilege to meet and speak with Ameet, as it gave the GGF an opportunity to discuss the role of glazing in reducing the nation’s carbon emissions, and all of the fantastic and innovative work taking place in our industry that can make a difference and contribute to the government’s Net Zero Targets for 2050.
