Product Description

  • Reduce excess heat by a few degrees
  • Save on air conditioning costs
  • Helps prevent fading of furnishings
  • Limited loss of natural light

Our HRF-40 Heat Rejection Film is designed to cut down by 80% the infra red light, and therefore shave a few degrees* off the thermometer and help you save on your air conditioning bills and make your room or office more comfortable. It will also help in limiting heat loss in the winter therefore saving on heating costs.

This product is ideal for home or office, and can be applied internally on any glass surface (data specs in the pdf below). This film is truly revolutionary as it enhances your comfort without the draw back of loss of natural light associated with reflective and tinted films. 

This film is very popular with businesses who want to save on their air conditioning costs, including retailers where applying tinted film on shop fronts is not an option, and offices with large windows which require constant temperature control with no loss of natural daylight.

We have supplied The UK Environment Agency with this product which has been installed on most of their sites.

*Please note that this product doesn't act as an air conditioning unit and is not designed to keep a constant temperature in a room. It is designed to help reduce ambient temperature by a few degrees and therefore save on air conditioning costs. 
For a more efficient product, please consider a tinted or reflective film but you will have to sacrifice natural daylight.
