What Role Does a Radiant Barrier Play in Insulating a home ?
lI have recently been reading up on radiant barriers that supposedly would reflect 96% of the heat that rises thru the ceiling. How effective is this material in conserving heat and lowering my heating bills. I live in the Northeast-MA and have old fiberglass batts in the attic floor. Unfortunately, there is only about 6 in of space avail to insulate. No insulation I use would get me to the R 39 value that the gov't recommends. What is the best way to maximize the insulation in this space? Would a reflective barrier be beneficial in this situation?
