Small front porch with polycarbonate roof

[TonyRPH]

We have a small porch (approx 1.5m x 1.5m) with a sloping polycarbonate roof.

With the warmer days, the heat being generated is quite intolerble, even with both windows open.

Would I have any issues with condensation or similar if I put a sheet of Celotex on the underside of the roof?

I'm hoping this would block sunlight coming through the roof and at the same time prevent heat from getting through the roof, although I appreciate there will still be heat coming from the sunshine through the windows.

Any other suggestions would be appreciated.

Thanks.

Thanks - yes I think I could form a perfect seal.

The roof is essentially a window frame with the polycarb panels inserted like glazing.

I could quite easily cut the Celotext to exactly the size of the frame and then affix it probably using some kind of supports from one side to the other.

This is a more detailed view of the roof if that helps at all.

You could also change the polycarb for the bronzed version, which will help. Simple job.

Interesting that you say that, because our side porch has the bronzed roof, and it is noticeably cooler - although I put that down to it not getting as much sun and being slightly larger.

I guess even a solid colour (if available) would help - we went for white because of it's reflective properties, thinking it would be cooler - but I guess it's letting a lot more light through!

Good idea.

I actually came up with an idea this morning.

I thought about using something similar to a Velux window blind.

It might need a bit of custom fitment though!
