Safety window film in Farnham
Solar control films reflect or absorb part of the sun's heat before it reaches the room, which helps with overheating in south and west-facing rooms, conservatories and offices. Darker and more reflective films reject more heat, but they also let in less daylight and change the outside appearance.
Window film is usually a polyester film with a pressure-sensitive adhesive on one side and a scratch-resistant coat on the other. BS EN 15752-1 sets out definitions and performance requirements for adhesive-backed polymeric film used on glass in buildings.
Many window films block most ultraviolet light, which is one cause of fading in furniture, floors and stock. Visible light and heat also contribute to fading, so film slows fading rather than stopping it. A clear UV film changes the view very little.
One-way mirror films give privacy only when the outside is brighter than the inside. During the day, people outside see a reflection. At night, with lights on indoors, the effect reverses and people can see in, so blinds or a frosted film are needed for night-time privacy.

Working in Farnham
- Postcodes covered
- GU9, GU10 and the surrounding area, including Aldershot, Fleet and Farnborough
- Coast
- Farnham is well inland, around 42 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Farnham the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Low winter sun and strong afternoon sun on south and west elevations cause the most glare and heat. Solar films reduce this but also cut some daylight, so north-facing rooms usually suit lighter films that keep as much light as possible.
- Access and setting
- Rural homes with conservatories, garden rooms or large glazed doors often face full sun and glare. Solar control and UV films help, but older glass and leaded lights need careful compatibility checks before film is applied.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.

Window Film in Farnham: questions
Why are there bubbles or haze after the film is fitted?
Film is applied with a slip solution, and a small amount of water remains under it at first. This can show as haze or small pockets that clear as the film cures. Curing takes longer in cold or damp weather. Do not press or clean the film until it has cured. Air bubbles that remain after curing should be reported.
How long does window film last?
Lifespan depends on the film type, whether it is inside or outside, and how much sun the glass gets. Internal films generally last longer than external films, which face weather and pollution. Manufacturer guarantees apply to the film, and the terms are confirmed in writing with your quote.
Does solar film make a room darker?
It depends on the film. Light-coloured and spectrally selective films reduce heat with only a small drop in daylight, while darker and more reflective films cut more heat and glare but also more light. The fitter can show samples on your glass so you can judge the effect before choosing.
Can window film make my existing glass safe?
A tested safety film can hold broken glass together and reduce the risk of injury from shards. Some films have been impact tested to BS EN 12600 when applied to glass, so ask for the tested class. In some locations, replacing the pane with toughened or laminated glass may be the more suitable option, and the fitter will say so.
