Very interesting about the angle of the glass, which I had not grasped before.I have three large panels of transparent conservatory roofing, double walled plastic stuff off a skip that people tell me costs around £60 per panel (just to clarify what this stuff is).Because it is so thick I wonder if it actually stops any heat getting through at all???Does anyone know if I could use it for a cold frame?I also have some glass double glazing from the same skip (with permission, indeed active encouragement) and have the same doubts.....
