Composition: CedarBoards Insulated Siding products are produced of components using CertaVin™ custom-
formulated PVC
resin produced exclusively by CertainTeed, extruded and fused with expanded Polystyrene (EPS)
foam insulation.

Technical Data: CedarBoards Insulated Siding is in compliance with ASTM D7793 specification for Insulated
Vinyl Siding,
the ASTM specification C578 Rigid, Cellular Polystyrene Thermal Insulation, and the
requirements of sections R703.13 of
the International Residential Code, and sections 1404.9 and 2603 of the
International Building Code. CedarBoards Insulated
Siding meets or exceeds the properties noted in Table 1.

Important Fire Safety Information: When rigid vinyl siding is exposed to significant heat or flame, the vinyl will soften,
sag, melt or burn, and may thereby expose material underneath. Although the expanded polystyrene backing is treated with
a
fire retardant chemical and will not support combustion, it is an organic material and should therefore be considered
flammable if exposed to an open flame or ignition source. Also, care must be exercised when selecting underlayment
materials because many underlayment materials are made from organic materials that are combustible. You should
ascertain
the fire properties of underlayment materials prior to installation. All materials should be installed in accordance
with local,
state and federal Building Code and fire regulations.

Sustainability:

 CedarBoards D6 contains a minimum of 60% post-consumer and post-industrial recycled material.
 Life cycle analysis tools such as BEES show vinyl siding to have a lower environmental impact than a majority
of
cladding options.
 Installation of Vinyl Siding eliminates the need for paint and caulk, decreasing maintenance and the
projects’
environmental impact.
 The majority of raw materials used to manufacture our vinyl products are shipped by rail, decreasing emissions
and
the need for over-the-road transportation.
 Unlike a majority of cladding choices, Vinyl Siding is recyclable. CertainTeed is leading an initiative to take
back
post-consumer siding from builders and manufactured housing plants, creating a “cradle to cradle”
system that
will close the loop on manufacturing our vinyl products.
 The manufacturing process used by vinyl producers is less energy and resource intensive than that used by
other
cladding choices such as brick and stucco.
 Can increase overall thermal performance, helping to reduce energy costs
 Almost 100% of raw material inputs are used in the manufacturing process of CertainTeed’s Vinyl Siding
product
lines, practically eliminating landfill waste from manufacturing these products.
