Solar Control Window Film
Solar control films cut the heat and glare from sunlight while keeping your view. Choose an internal grade for most windows, or an external grade for double glazing that overheats. Darker reflective grades give the strongest heat rejection and daytime privacy; lighter grades keep more natural light. Every grade blocks the large majority of UV to help protect your furnishings.

Buying guide
Reflective grades reject the most heat and give daytime privacy, but keep rooms darker and need care on double glazing. Neutral tints avoid the mirror look. Near-clear spectrally selective films keep the view bright while still cutting infra-red heat. If you are unsure, order A5 samples or use the Film Finder, and always check glass compatibility before buying.
