Our heat rejection films are ideal for your home, office or retail outlet, and can be applied directly on any smooth glass surface. Window film is truly revolutionary as it enhances your comfort for a fraction of the cost of curtains and blinds, whilst still allowing you to see out, with little loss of natural light.

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. 

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.

These films don't target excess glare. Are there any other options?

Yes, but to target excess glare, you will have to sacrifcie visible light transmission by tinting the glass. Here are a few options:

  • Tinted film works by darkening your windows, like a pair of sunglasses, and therefore reduces excess heat and glare, but there is a loss of natural daylight.
  • Reflective films work similarly to tinted film but are much more efficient, and add daytime privacy as a bonus.

How much money will I save on air conditioning bills?

Every case is different but even a few degrees difference will make for big savings, especially in buildings with large windows. 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.

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

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 film removable?

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 10 year warranty, but will last much longer in the right conditions. External films have a lower warranty. Please check the product's detail.
