Radiant Heat - Boiler Working Overtime?
Bill -
The most effective way to attach the foam board is with liquid nails
(the one that is formulated for polystyrene - check the label) and
strapping mechanically fastened directly into the concrete. As far as
the seams...a lot of things work well, I like to use 1 component foam
at each of the seams and the top, but plenty of other things work
well.
