Fiberglass insulation does not have to be dealt with with chemicals to make it fire-resistant, and it does not turn out to be anymore combustible because it ages.

They survive a flash above not as a result of R-Price but reflectivity/emissivity. The same as You can not Evaluate thermal mass in log houses with R Worth. There may be physics at perform that compensate for or get over R-Benefit. Radiant Barriers function, utilize them and do not forget the 3/4" air gap.

Cold weather installations necessary a very diverse thoughts-set. To reduce heat decline, a perforated radiant barrier needs to be located among the ceiling and the mass insulation by having an air House in between the ceiling as well as barrier.
