Heat Insulation Film

Insulation Window Film & Heat-Reflective for Offices - Hitchin, Herts & UK


Used in thousands of commercial buildings around the world, heat-reflective and insulated window film can help manage your offices heat control and air conditioning costs, while providing an affordable and healthier environment for your employees to work in.

  • Does your commercial building suffer from excessive heat?
  • Do your staff suffer from computer screen glare?
  • Is the sun fading your office fabrics and furnishings, requiring replacement expense?
  • Are your office window blinds absorbing heat and adding to your problems?
  • Can your heating or air-conditioning costs be reduced?
  • Do your members of staff complain about high office temperatures during the summer?


Window insulation film will retain heat, while its solar properties will lessen the sun’s heat by up-to 80% in your office or factory, while reducing unwanted glare by up-to 85% and office furniture fabric fading by 99%.

Window films’ one-way mirror finish will also deter would-be intruders and provide office privacy for members of staff, as well as offer a higher level of security for commercial premises including bomb-blast protection.

Window film can be applied to your property without making your offices dark and provide a natural view from your windows. If you care about your staff and creating a productive and safe working environment, this is the perfect option for energy saving, conscious employers.

Unhealthly UV sun rays can disrupt work within your business causing illness, fatigue and excessive glare on computer screens, which in turn cause headaches and loss of productivity. Why not create a far better climate for your environment with a window system that is easier to maintain, more attractive and far more cost effective than old fashioned window blinds.

Solar film is the high-tech 21st Century replacement for Blinds. Film reduces glare and eliminates heat build up, yet does not cut out light or require expensive cleaning. What’s more, blinds attract dust and insects and are difficult to clean. Once window insulation film is installed, there are no maintenance costs as they can be kept clean by simply wiping with a moist sponge or cloth.

Prism window film is designed in such a way that heat build-up is reduced during the hotter days, while increasing retained heat.

As window film specialists, Prism will advise you on the right film for your commercial and environmental requirements. Our film is maintenance free, lasts up to 20 years and is suitable for glass or polycarbonate roofs and windows.

Workplace Regulations 1992, #14 requires employers to ensure that glass within their commercial premises are fully risk assessed and qualifies as “impact-safe” or “safe-breaking” and clearly marked with manifestations.
