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 infra red light, the main cause of solar heat gain by 80%. It will reduce ambient temperature by a few degrees therefore making your office or room more comfortable, and help you save on your air conditioning bills. 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. This film is truly revolutionary as it is virtually clear with just the lightest of colouring, therefore enhancing your comfort without the draw back of the 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:
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 using a tinted or reflective film instead, but you will have to sacrifice natural daylight.

Not sure whether this is the right film for your purpose? We offer free 10cm x 10cm samples. The pictures depicting the film are only for illustration purposes, so a sample is recommended to make an educated choice.

If you'd like to try a larger piece before committing to a large order, just order a small amount of film, or a cut to size piece to test on a pane.

Returns and refunds
We will only accept returns for films purchased by the metre. Just send it back to us in it's original condition and packaging. We cannot accept returns for films cut to size however, as they have no resale value.
