Space between shade cloth and greenhouse roof.
My greenhouse is within 2 feet of the main house. The city fathers don't like that because the fat firemen cannot squeeze through the space in case of a fire, 4 feet is the minimum required. They are making me rebuild it attached to the house, which is OK, because obviously no brain dead fireman would attempt to squeeze through a non existing space. This gave me an idea.
I have the black shade cloth separated from the roof of the greenhouse by 1 1/2 feet allowing for ventilation and combating heat buildup. I'm rebuilding it with Aluminet and using clear Lexan for the roof. What if one allowed NO space between the two? If they are on top of each other with zero space between them, there can be no heat build up in this non existent space. Has anyone tried this?
