 Re: Vent for Gable House
Tech shield is OSB (Oriented Strand Board), the random chip looking wood sheeting, with aluminum foil on one side to reflect IR. It is made specifically for roof decking to lower attic temps. I used it to reflect any heat inside away from the decking and as an extra barrier for the wood, since we are not concerned about solar heating.
OSB is about 2 times stronger in shear than plywood. But either will do for a roof.
