Product Description

  • Helps prevent heat gain
  • Save on air conditioning costs
  • Helps prevent fading of furnishings
  • Limited loss of natural light
  • Ideal for retail outlets
  • Buy by the metre (1.52m and 1.0m width)

Our SER-50 Heat Rejection Film is solar control film designed to prevent slow wave infrared components responsible for heat gain, from going through the glass and into your room. 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 blue 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.

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. Please check product Specifications for glass compatibility.

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.

Will this film reduce the heat by several degrees?

It all depends on a range of factors. If you have a large room with small single pane windows, then the effect would be more felt than if you had a large south facing double glazed window in a small room. On a large building with hundreds of windows, the cost benefits would be greater than in a small office with a couple of windows.
