Hello,

we have a patio roof that is enclosed on three sides. Currently, there is no awning installed above or below the twin-wall polycarbonate panels. Last summer, it became warm and stuffy under the roof (south-facing side).

Now I’m considering how to improve this for the coming summer. I thought about a tension wire system but I’m not sure how effective that would be. Does anyone have experience with this? Installing an awning above the roof is not an option for us… that would probably be the best solution, but unfortunately it’s not feasible.

Has anyone used ceiling fans? Are they effective? Our patio roof covers about 30m² (320 sq ft). For this size, I was thinking of using two ceiling fans.

I would appreciate any advice or experience reports.

Thank you and best regards

The best solution would really be exterior shading, but if that’s not possible, you first need to block direct sunlight on the seated area (this can be done with any indoor shading). It will still heat up, and I don’t think ceiling fans will help much (there are also some issues with shading, although not unsolvable). You need horizontal ventilation instead, since the hot air needs to be moved out, but 1–2 regular fans can be quite effective. The ideal solution would then be to lower the temperature below the ambient level, which can be done with water. This could be a (raised) pond or fountain element, or (more effective but requires electricity) a misting system.

Well, you really have to think about this: a patio roof with two fans and/or an awning for heat protection...

Consider whether you actually need this roof including side protection, and why.

If not, consider selling it and looking for alternative furniture options.

Because honestly, this method doesn’t sound very effective.

It’s like going on a ski vacation but spending 12 hours a day in the spa area because you don’t like the cold.
