How does radiant barrier work? On a
hot day, your roof shingles absorb solar heat
and warm up the sheathing below, which
radiates heat towards the attic floor where
conventional insulation is typically installed.
A radiant barrier blocks up to 96% of this
radiant energy. It reduces heat transfer
by thermal radiation across the air space
between your roof and the attic floor,
keeping your attic cooler. In cool weather,
it helps keep radiant energy from leaving
the home, reducing heat loss.
My home is insulated. Do I also need a
radiant barrier? Yes. Conventional insulation
and Enerflex work together by reducing dif-
ferent forms of heat flow. Insulation slows the
movement of heat by conduction. Enerflex
reduces the movement of heat by radiation.
Enerflex improves the performance of your
existing insulation by limiting the flow of radi-
ant heat from the roof to the attic floor, mak-
ing the top surface of the insulation cooler.
How how much Enerflex do I need?
Enerflex comes in flat panels and in rolls,
to meet your specific needs. Visit Enerflex-
Foil.com and click on the materials
calculator to quickly estimate the
number of panels you will need.
Will a radiant barrier harm my
shingles?
No. Typically, a radiant barrier
will increase the temperature of your shingles
2 to 5 degrees. This minor elevation in tempera-
ture will not affect the life of your shingles.
Do I need special tools to install
Enerflex? No. Enerflex panels simply "flex"
into place. Enerflex rolls are simply stapled.
Recommended tools and safety equipment
are listed in the installation instructions, to
make your installation go smoothly.
Does Enerflex need to be taped?
We recommend overlapping the radiant bar-
rier edges by 1" to 2", which does not require
taping. While not required for cut edges or
seams that butt together, the best results will
be achieved by taping with reflective tape.
How much space is required for proper
ventilation? Check with your local build
code official for ventilation requirements in
your area. The unique design of Enerflex will
allow an unobstructed space for airflow from
the soffit vents to the wind ventilators or
ridge vent. A minimum gap of 3.5" is required
between the top of the roof decking and
Enerflex. Leave a minimum of 6" from the
peak of the roof, or 6" in all directions from
any turbine, turtle back, gable or mushroom
vent. Never cover any vents with Enerflex,
regardless of where they are located.
Is there a warranty? Yes. Enerflex Radiant
Barrier is covered under a 15-Year Limited
Warranty.
