Are heat blocks effective without dead air space?
I'm working on installing STEP warmfloor radiant heat, and I'm looking for a material to install under the heating element that will limit the amount of energy lost to the crawl space under the house.
So far I've only been able to find products aimed at hydronic radiant heat systems, rather then the heat pads like STEP, and those are all to be installed under the house, rather than on top of the subfloor. Is there a product that i can install directly under the element?
