The Solar Grey panels have a 35% light transmission. The panels do not reflect heat. The only color that reflects heat is the Solar Control Silver
The light is even. The corrugation does not cast strange shadows - at least as far as we've been able to tell.
Each sheet covers 2' width-wise. We recommend 4-6" overlap length-wise. Please visit www.palram.com/us. There is a project calculator on the Suntuf product page.
It says it stops the UV rays but they don't stop all the sunlight. I have used them on two decks, a sun room, an aquaponics greenhouse and a garden pergola. I live in central TX where the sun is hot. Where I need comfortable shade - open deck, I have added movable shade cloth underneath the panels to provide adequate shade and cooling. The panels although appear dark, do not block enough sunlight to do much cooling in hot climates.
Please provide your original question and we will be happy to answer it.
I had a 16ft run and decided to use the 12ft and cut some in half to give me some overhang and sufficient length to overlap the joints. You might try contacting Suntuf to see if they come in 16ft lengths
We have cut it with a saber saw. It must have a fine blade, like a blade made for cutting metal.
Snow load is determined by purlin spacing. Please visit www.palram.com/us to visit the Suntuf product page and view the installation instructions.
I live in Central Texas where my 5 installations are located, so snow is not an issue. But having said that, if you put the support under them like you would any other roofing panels the should be fine. I did put some on grandkids backyard stage/playhouse in Idaho Falls and they have been fine.
Only if they are going on an enclosed area that you don't want open to the bugs, etc. I have them on three decks without the strips and they are not structurally necessary.
