Description
Our rFOIL 4320 Standard
Concrete Underpad is an
outstanding reflective
insulation and
puncture-resistant vapor
barrier.
rFOIL 4320 Standard Concrete
Underpad consists of a double
layer of polyethylene bubbles
sandwiched between an
aluminum surface and a clear
polyethylene sheet. It is
ideal for many under-slab
insulation applications
because a protective film is
applied to the aluminum
surface virtually eliminating
the risk of corrosion.
Using rFOIL 4320 Standard
Concrete Underpad in your
construction project can
improve the efficiency of
radiant heating systems and
significantly decrease heat
loss to the ground below when
properly installed with the
clear side facing upwards.
rFOIL 4320 Standard Concrete
Underpad provides exceptional
thermal value and a strong,
permanent vapor and radon
barrier.
Use rFOIL 4320 Standard
Concrete Underpad as a
cost-effective alternative to
rigid foam insulation.
