INSTALLATION INSTRUCTIONS FOR RADIANT BARRIER (RB)
Before You Begin
Be sure you have the
following tools and materials:
A. Proper amount of ALUMA-FOIL SUPER PLUS
radiant barrier.
B. Tape measure, drop light, shears, utility
knife and stapler (mechanical, electrical or air-squeeze or hammer type)
C. Two movable support surfaces such as 2' x 3'
x 1/2" plywood or 1" x 12" x 3' piece of wood (lengthen for
24" O. C. trusses)
Safety Practices
Be sure you observe the
following safety rules:
A. DO NOT lay RB on top of exposed electrical
wiring or boxes.
B. Make sure trusses or rafters are sound before
placing your weight on them.
C. Be sure you have adequate ventilation and
lighting. A dust mask is suggested.
D. Protective headgear (bump cap) and safety
glasses are suggested.
WARNING: DO NOT attempt to stand or lay on existing insulation.
Failure to follow these instructions can and may result in
serious injury and damage.
Truss Or
Rafter Mounted Installation (Fig 2)
1.
Measure, roll out and cut the RB as needed in sizes that are best handled by
two people.
2.
Whether you start at the top or bottom remember to leave three inches (3")
between the
RB
and existing insulation at the bottom and six inches (6") between the two
pieces of
RB
at the ridge or peak (Fig. A). This allows proper ventilation of your attic
area.
(Fig.
3 below)
3.
Staple the RB approximately 6" - 8" on center on all wooden members
using a 1/2" or
9/16"
crown staple with 1/4" or 5/16" leg. (C)
4.
It is not necessary to overlap the product or tape the seams. Cut around wood
members
as
necessary. (B)
5.
In this application it is very important to cover all small (knee) walls and
gable end walls
6.
Be sure to cut around all vent openings in the roof, or gable end wails, after
covering
those areas.

Ventilation
(Fig 3)
1. Because ventilation can greatly enhance your
RB
performance, it is important to consider
the following:
A. Where no existing ridge or gable vents exist
you
should
install one system or the other. Consult
vent
manufacturers
instructions for proper location and installation.
B . Where no soffit vents exist, be sure
ridge, pan or
gable end vents are of adequate size to
properly
ventilate area.
NOTE: Advanced Foil Systems does not
recommend
attic floor installation due to the
accumulation of dust
which will cause a loss of performance.
