Insulation / Low-E Window Film
Low-emissivity insulation film reflects internal heat back into the room in winter and reduces solar gain in summer. Its greatest benefit is on single glazing where replacing the glass is not practical. Insulation performance is system-dependent, so we only state figures backed by verified data.

Buying guide
We do not claim a major insulation improvement without system-level evidence. On double glazing the benefit is limited — ask us for a review of your glazing.
Frequently asked
Each product page lists suitable and unsuitable glazing, and asks for your glass type before you add to basket. If your glazing needs a check, send us the build-up and pane sizes and we confirm in writing before you order.
