Conservatory too hot? Your options
Glass or polycarbonate roof — the film you need differs.
Last reviewed 6 August 2026Technical reviewer: WTC Films Technical Team
Conservatories overheat because the roof takes the full force of the sun. The right film depends on your roof material.
Glass roof
Use an external reflective solar film. It reflects heat before it reaches the glass, cutting overheating while reducing thermal-stress risk. See WTC Roof Solar External.
Polycarbonate roof
Use the specialist polycarbonate film — WTC Roof Solar Polycarbonate. Because polycarbonate varies by manufacturer, we recommend a test piece before a large order.
Side windows
Treat these like any window — a solar or neutral film reduces heat and glare at eye level.
