I want a radiant barrier but can’t get it.
We had the roofing company put down a 1/4″ (I think) plywood decking on our roof without the radiant barrier on it. Bad advice or not, we do not have a radiant barrier.
Two different companies that specialize in the spray-on barrier have told us that our house would not be a good candidate for the spray-on barrier — something about our having a large vaulted ceiling, and the area without that attic space (and thus not the spray), would reduce the benefit to to point that it wouldn’t make sense.
We are now going to be getting another roof within the next few months due to the big hailstorm in late September — an adjuster just came to our house and gave us a check this morning.
That is all background. Here is my question.
CAN YOU SEE A WAY WE COULD ADD A RADIANT BARRIER TO OUR ROOF? I had two thoughts about it. First: I am wondering if the plywood with the radiant barrier can be laid over the existing plywood to create the radiant barrier. That would be the radiant barrier sandwiched in between two layers of plywood. A downside to this could be that it might create heat that, instead of being dissipated in the attic, would be instead put on the lower layer of plywood and be a fire hazard. Would this ever work?
Second thought: If we really wanted to have the barrier, would that mean taking up the old plywood decking and replacing it with a new decking with the radiant barrier? Then, would it be worth the expense of doing so?
