Hi all, I bought an Aluminium greenhouse with PC sheets as the glazing about 3 yrs ago. The original sheets have pitted and cracked. Fortunately, I have similar sized sheets from a previous purchase that went wrong. There is a bluish tinge to the sheets, I'm assuming to be UV protection. The sheets have a clear film one side and a white film on the other: am I right in thinking the UV protected side is with the clear film and installed facing outside. I don't have the instructions from the previous purchase unfortunately. Thanks for any help, rgds
