Radiant Barrier
Problem (Summer Conditions):
Solar radiation causes roof temperatures
to reach 160 to 190 degrees Fahrenheit.
Heat is conducted through roofing
materials and reradiated to the mass
insulation and ceiling below.
Attic air temperatures climb to
superheated levels…typically 140 degrees
Fahrenheit in the summer.
Radiant heat transfers into air conditioning
ducts increasing energy costs.
Attic structure and contents saturate and
continue to transfer heat even after the
sun has set.
Air Conditioning (A/C) run time increases
and in peak loads cannot maintain internal
temperature set points – comfort is
compromised.
What is the Solution for this problem?
An attic radiant barrier.
Radiant barriers consist of at least one low
emittance (0.1 or less) surface (usually aluminum
foil) bounded by an open air space, for the primary
purpose of limiting heat transfer by radiation.
Aluminum foil has the properties of High reflectivity and Low
emissivity and blocks up to 97% of radiant energy, so heat
transfer through radiation is significantly reduced.

Application
Unique multi-layer design has two layers of protection AND the installation
covers a large percentage of the underside of the roofing and framing.
What is the main advantage of installing a Radiant
Barrier in your home or building?
LOWERS ATTIC
TEMPERTURE UP
TO 30 DEGREES
Radiant barriers are very
effective at reducing radiant
heat transfer, which is often
the primary source of heat
gain and loss in a structure.
Radiant barriers work with
standard ventilation (soffit
and roof vents) to create a
system that reduces heat
gain.
16” & 24” widths for trusses and rafters
30” width for hip roofs and gable ends

Another Solution:
Silver Shield Radiant Barrier can be
used to meet Energy Star Criteria for
“Fully-Aligned Air Barriers” of the
Thermal Enclosure System Rater
Checklist, by insuring insulation is
fully aligned with air barrier.
Also meets building code flame
spread and smoke developed ratings
required for wall systems; Silver
Shield has a Class A flammability
rating.
