Fi-Foil Co., Inc. multi-layered B-3 Silver Shield reflective foil
insulation is one of the most effective insulations on the market.
It resists all modes of heat transfer: convection, conduction and radiation.
B-3 Silver Shield can be used in stud and masonry walls, ceilings,
floors and roof rafters as a radiant barrier.
Foil-Faced Foam Sheathing board is composed of a
uniform closed-cell polyisocyanurate foam core bonded on each side
to a trilaminate foil face.
One side has a printed foil reflected
face and the other side has printed non-reflective foil face, depending
on your building needs.
The superior properties of polyisocyanurate
produce the highest degree of insulation efficiency.
