A conservatory that hits the mid-30s°C in summer is one of the most common problems we're called about. There are several "fixes" people try — most disappoint. Here's what actually works to cool a conservatory, and why.
Why blinds and fans disappoint
Conservatory blinds are expensive and only partly help, because they absorb heat inside the room and re-radiate it — and they block the light you built the conservatory for. Fans just move hot air around. Neither tackles the cause: solar heat pouring through the glass.
Solar film on the roof — the real fix
Most conservatory heat comes through the roof, so solar film on the roof glazing gives the biggest temperature drop, rejecting up to 79% of the heat before it enters. Sun-facing sides can follow. It keeps the room bright, works permanently, and costs a fraction of replacing the glass.
What difference to expect
A conservatory that was unusable on sunny days typically becomes comfortable and usable again, while staying light. It won't be air-conditioned-cold, but it stops behaving like a greenhouse — and it protects your furniture from fading too.
Cheaper than the alternatives
Against new solar-control roof glass or a solid roof conversion, film is far cheaper and fitted in a day with no building work. Our Conservatory Cooling Calculator gives an indicative temperature drop.
The bottom line
To actually cool a conservatory, put solar film on the roof glazing — it beats blinds and fans, keeps the light, and is fitted in a day. Book a survey and we'll assess your roof.
