All your Window Film questions answered
Can I install window Film DIY?
Although it is possible for a practical person to install the standard range of window films it is recommended that an experienced installation technician should be utilised. Apart from ensuring an acceptable aesthetic finish it will mean that a full warranty (typically 10 years) can be obtained.
Why use a GGF Member?
The use of a GGF will ensure that the installation will meet all the stringent industry standards applicable. These cover all aspects of the installation from visible appearance through to thermal compatibility to make sure the installation does not cause any detriment to the glazing system
What is Window Film
Window is a base of clear polyester which is either then dyed, extruded or metallised to produce a product that reduces heat and glare from the sun that increases comfort and reduces energy usage.
Is Window Film suitable for both New and existing buildings?
Yes film is suitable for both new and existing buildings however its greatest use is being retrofitted in existing buildings.
Will Window Film stop my Conservatory Overheating?
The use of a high performance window will dramatically reduce conservatory overheating making the space much more user friendly.
Do I need Planning Permission?
Planning permission for film is not normally required.
Is Window Film Bullet Proof?
Window films are not bullet proof, blast proof or burglar proof. However they will give a greater level of safety and security when used for these purposes. You should always ask for the appropriate certification when using window film for these reasons.
How is film maintained once installed?
Once installed window film should be cleaned in a similar way to glass and a soapy water solution and squeegee are ideal. However abrasives of any type should be avoided.
Does window film improve both U and G Values?
Yes film will improve both the heat gain and heat loss properties of the glazing system.
What are they for?
Films can broadly be divided into 4 types: solar control, safety/security, automotive and privacy. Advances in manufacturing techniques now allows for 2 or more of these types to be combined into one film.Solar Control films are designed to reduce incoming solar heat, glare and ultra violet (UV). They are available in many colours and tend to have 3 or 4 ‘strengths’ per range- from high-reflective to very light. Solar films can totally transform a building by giving it a uniform colour and hiding untidy looking office environments- such as the backs of work desks, wiring, etc. Many buildings can benefit financially from an application of solar control film in the form of reduced air-conditioning costs.Safety/Security films range from 50 microns to 350 microns and more. They are extremely tough and hold glass together in the event of accidental or malicious impact. Safety/security films are used extensively in commercial buildings to bring glazing up to current British and European safety standards. The heavier gauge films are often specified in high-risk areas such as banks and government buildings. They resist unwanted entry and protect occupants from terrorist and accidental explosions.From totally opaque to a light sand-blasted appearance and available in every colour imaginable, Privacy films offer an attractive, cost effective solution for creating privacy or hiding areas of a building. Typical applications include cloakroom privacy, hiding curtain-walling behind large panes of glass and creating private areas within office environments.
I think I need a solar film but don’t want a mirrored look.
Whilst a silver solar film can make a building look very modern it would not suit a domestic application or an old, historic building. However, there are several neutral films available which can give maximum protection yet are hardly noticeable. Also, sputtering technology has led to several high-performance films which are extremely light.
How long will it last?
Window films are extremely durable and typically last 5-10 years and more, depending on where they are applied. There are documented cases of films lasting longer than this.
What happens if I want it removed?
No problem. The film itself can be pulled from the glass which will generally leave adhesive residue on the glass. This is removed by spraying with soapy water and using a razor-scraper. No need for any over-powering adhesive removers.
Can I clean the window after a film is applied?
Yes, using a soft, clean cloth or paper towel to clean and the same or a rubber squeegee to dry. Use mild detergent or every-day glass cleaning solutions. Basically, avoid using abrasive tools and chemicals.
