Radiant Barrier Roof Sheathing
Many building supply companies offer a plywood or OSB (oriented
strand board) sheathing product with a radiant barrier already laminated to
one side of the board. This radiant barrier roof sheathing product is generally used for new
roofing applications where the radiant barrier sheathing product is used as
the roof decking with the radiant barrier side laid downwards towards the attic.
Felt and shingles are then applied as usual over the sheathing decking.
This method of installation is easier for construction and
roofing companies because it combines two installation steps into one thereby
saving time: 1) installation of the radiant barrier and then, 2) installation
of the roof decking.
However, these pre-laminated radiant
barrier plywood/OSB sheathing products are very expensive.
We offer a simple solution to radiant barrier plywood/OSB
sheathing products to combine the installation steps:
Ultima 48" width radiant barrier can be easily stapled to a sheet of plywood or
OSB before the plywood is installed as roof decking.
With RadiantGUARD® radiant barriers, you can create
your own radiant barrier plywood sheathing that is:
Of Higher Quality Tear and Puncture Resistance - Many
OSB radiant barrier manufacturers use a lightweight radiant barrier
which can easily tear during transportation or construction site storage.
Breathable - Using our perforated radiant barriers
in this application guarantees you the comfort in knowing that you have
a "breathable" product. Some manufacturers have had issues in
the past with the glue used during the lamination process "sealing"
up any perforations that may have existed in the barrier before the
manufacturing process. It is important to have a breathable sheathing
to allow moisture generated within a building structure to pass outside
the building envelope to reduce condensation buildup which could potentially
result in damage to other insulation and wood structure supports.
Less Costly - This application is approximately
1/5 the cost of pre-laminated radiant barrier plywood/OSB
sheathing products on the market today.
All RadiantGUARD® radiant barriers meet
the Standard Specifications for Sheet Radiant Barriers for Building Construction
Applications ASTM C1313 and the
State of California Title 24 Insulation Standards and are ENERGY STAR qualified
