Hi guys- I have a large room that has a good radiant floor system. I followed the advice of the installer and merely put up that radiant silver material on thwe bottom of the joists to contain the heat etc. My boiler has a hard time keeping up when it gets real cold, so I use a big wood stove in that room too. As you may guess, I know I have too much heat loss to the unheated basement. So I have been thinking about three possible solutions: 1) Remove the radiant wrap, insert non faced or paper faced insulation, reapply. 2) Same, but insert foil backed insulation 3) This would be easiest- Put blueboard over the entire basement ceiling, leaving the radiant wrap in place under it. Opinions from the insulation pros?
