HIGH EFFICIENCY
UNDERLAYMENT INSULATION
AIR INFILTRATION
In most homes the movement of air from
inside out and outside in, is the single greatest cause of
energy loss. Areas most greatly affected by air infiltration
are window and door frames, sill plates, and through the
wall itself. Shelterwrap underlayment insulation, when
installed properly, is designed to eliminate costly air
infiltration. Shelterwrap is manufactured of expanded
polystyrene laminated with durable, highly reflective, foil
laminate skin or a heavy kraft paper. Shelterwrap is
manufactured in one continuous sheet measuring 4 feet in
height by 24 feet in overall length. Being manufactured in
this manner gives Shelterwrap a clear advantage in
eliminating seams and cracks on the wall, developing a total
wall insulation system.
Shelterwrap provides permeability which allows wall cavities
to breathe, thus reducing the risk of condensation within
the wall.
The effectiveness of a particular product to slow down or
eliminate air infiltration is measured in "R value", which
means resistance to heat flow. The higher the R value the
greater the insulating value. To get the marked R value it
is essential that any insulation be installed properly.
