Low-E Silver Window Film


Low-E window film has a special coating which reflects the heat back into your room on the inside. It has a reflective external coating which reflects the sun’s heat away in the summer. Make your room cooler in the summer and warmer in the winter. Lower the cost of running air conditioning and heating. Save money on your energy bills. This saving could pay for itself very quickly, especially on single-glazed windows. The film reflects bright sunlight, reducing glare on TV and computer screens. It reflects 99% of ultraviolet (UV) rays protecting everyone’s skin. It will slow down fading (or bleaching) caused by the sun. This Low-E window film has a mirrored external appearance which can provide daytime privacy (under the correct lighting conditions). It’s sticky-backed for an easier installation and no chance of creating a mess. Care should be taken during installation as this film does not have a scratch-resistant coating. It’s not possible to have a scratch-resistant coating due to the Low-E coating.

Q & A

Is the Low-E Silver Window Film suitable for bog standard double glazed windows in a house? Jane asked on 17 April 2024

Its only suitable if the glass is toughened. If they are not toughened there is a small risk it could cause the glass to crack

Can it be removed and reapplied? And how can I tell if my current double glazing is toughened glass? Thank you SJ asked on 28 November 2023

It’s wet applied giving you a short time to move it into place and remove it to reapply if needed. Once it’s been left to dry then it will be able to be removed but will be damaged so can’t be reapplied. Depending how long it’s been on you may need to get a glass scraper to remove any adhesive residue that’s left on the glass. If you can let me know what text is on the kite mark in the corner of the glass I can check for you

Would it stick to polycarbonate? David asked on 3 November 2023

No this isn’t suitable for polycarbonate

Paul Foster answered on 15 November 2023 store manager

The only window film suitable for polycarbonate is Coolkote which can be found here https://www.evowrap.co.uk/product/coolkote

How much light does it let through? The technical information says 16% light transmission – does this mean it only lets through 16% of light meaning it is a very dark film? Also how much heat does it conserve? The technical information mentions how much heat it stops entering through the window but it doesn’t say how much heat it retains. Thank you. Sam asked on 29 September 2022

Yes, it does let 16% of light through, which is what gives it such high performance. It does sound a lot darker than it actually is, though. If you've got a lot of glass in the room it's not normally a problem. It stops up to 33% of winter heat loss. On standard clear double-glazed windows, you're looking at around 28%.
