Heat Rejection & Window Insulation Film

Our window insulation films are designed to reduce heat gain whilst allowing plenty of natural light through. Ideal for your home, office or retail outlet, you can purchase our window insulation films by the meter or cut to size. As a rule external films are the most efficient, followed by tinted and reflective films. Our SER and HRF films are ideal for retail outlets as they have virtually no associated loss of natural light.

Frequently Asked Questions
  • How much money will I save on air conditioning bills?

    Every case is different but even a few degrees difference will make for big saving on air conditioning costs. Solar and heat control window films will also help with your heating bills by keeping some of the heat that would otherwise escape through the glass.

  • What is the best heat rejection window film?

    For single pane glass, any of the films will be suitable and have an impact on the temperature. When it comes to double glazed units, the issue is complicated by the fact that a film would trap some of the heat within the pane so for best results an external film is by far the best option. If you don't have the ability to apply the film externally, then an internal tinted or reflective film is the best option. For retail outlets where a tinted film is not an option, our HRF-40 and SER-50 films are the best option as they our vistually colourless once applied to the glass.

  • How does window insulation film work?

    Heat rejection films have layers of thin particles and material, which act in a spectrally selective way, mainly by targeting short wave infrared (SWIR) components of the light spectrum, preventing the heat gain cycle from taking place, and therefore making your room cooler.

  • What is heat gain?

    Heat gain, also known as greenhouse effect, is what makes your home or office too hot on sunny days. Once sunlight goes through the glass and gets in contact with carpets, furniture and other objects, it is converted to long-wave infrared radiation which is unable to escape back through the glass, therefore creating and trapping heat inside the room. 

  • Is window insulation film easy to DIY?

    Window film is a self adhesive material applied using a soapy water solution and a squeegee, making bubbles a thing of the past. Please click here to view our installation tutorials.

  • Is the heat control film removable?

    Absolutely. You will need a spray bottle and some soapy water, and as wide a glass scraper as you can get. Click here to view our range of window film installation and removal tools

  • How do I clean heat rejection film?

    Just clean with soapy water and a squeegee, that's all. Do not use anything abrasive on the film or it will scratch it. Wait 4 weeks after installation before you clean the film.

  • Is there a warranty?

    Most of our heat rejection films come with a 7 to10 year warranty, but will last much longer in the right conditions. External films have a lower warranty. Please check the product's Specifications.

  • How is solar control film manufactured?

    Most solar control tints are made of layers of different materials and fine metal particles, which are bonded together. This is what makes residential and commercial films different to car tints, as car tints are usually just single layered dyed films. Typical composition is as follows:

    •  "Hard" scratch resistant layer, for durability and ease of maintenance during window cleaning

    • High optical quality polyester, with anti IR metal particles deposit

    • Bonding adhesive

    • High optical quality polyester

    • Pressure sensitive adhesive, glass polymerization within 15 days

    • Protection release liner, disposable after installation
