Thanks everyone for your thoughts, I do have a company sending some samples of a heat reducing film designed for twinwall conservatories but yes our other option was to create some shade, either by using some sail shades or another method. I expect cost is right, as a charity that was foremost I expect but it seems to be the wrong building for the job. Ripping it down isn't really an option so we must adapt! I'm only involved as I'm the IT guy and I put some smart temp monitors and fan controllers in to try to get the temp down but even at full tilt the fans (which are industrial grade) only drop the temp by 2 degrees. I'll report back how we get on.

It's being used to keep some aquatic animals in, I won't be too specific but suffice to say it's too hot as is. I am not sure of the reason this building was chosen. There are doors at both ends but security means they can't be left open.

I know, sounds daft but we have had someone build a polycrub at a charity and it's waaaay too hot. With an ambient temperature of 20 degrees outside and with two extractor fans running we are seeing temperatures of 38 degrees centigrade. We are hoping that we can use some sort of IR blocking film that's usually used on glass conservatories and windows but I wondered if anyone has done this on curved polycarbonate and if it's recommended? Also, the black poly pipe that supports the structure is black and acts as a giant heat pipe when in the sun, is there any reason we couldn't vinyl wrap the pipe in white to stop this? Thanks Graham
