VERSI-FOAM® SYSTEMS BY RHH FOAM SYSTEMS STANDARD SYSTEMS
spray foam insulation product is recommended for most commercial and industrial
applications. Ideal for air-sealing, insulating and condensation control.
FLAME RETARDANT (FR) SYSTEMS
systems have added flame retardants which reduce the flame spread and smoke
development of the foam. Suitable for insulating inhabited buildings, including
residential applications or any applications in which flammability is a
concern. Classified as Class I in accordance with ASTM E-84.
ABOUT CLOSED CELL SPRAY FOAM
2 lb closed cell spray foam insulation kits are available in two different
formulations: Standard Formula and Class I (flame-retardant) Formula. The
Standard Formula provides an R-value of 7.7 at a one-inch thickness.
Recommended for most commercial and industrial applications, the Standard
Formula is ideal for air sealing, wall or ceiling insulation, condensation control,
sound dampening, structural enhancement, tank and pipe insulation, roof repair,
marine flotation, truck/trailer insulation, sculpting and molding, pool and spa
insulation, and much more.
Class I (flame-retardant) Formula provides an R-value 6.7 at a one-inch
thickness. Classified as Class I in accordance with ASTM E-84, these
flame-retardant kits will limit the flame spread and smoke development if
exposed to a fire. Class I closed cell spray foam kits are recommended for use
in inhabited buildings, including residential applications or any application
in which flammability is a concern. Always consult your local building codes to
determine if a flame-retardant product is required for your application.
of our Class I kits are manufactured with an anti-microbial formula that stops
mold from growing on the surface of the foam. All Versi-Foam® products are
naturally mold resistant, but the added anti-microbial element provides a
safeguard against the growth of the five most common types of fungi found in
ABOUT OPEN CELL SPRAY FOAM KITS
open cell foam kits have a density of approximately 0.75 pounds per cubic foot.
It is 92% open cell and has an insulation R-value of 4, lower than the other
Versi-Foam systems, but still superior to some of the other commonly used
insulation materials. The appeal of this product is its high expansion rate.
Less foam is needed during application which makes it more cost effective.
cell Versi-Foam® kits are particularly dependent on temperature. The yield of
open cell products will be greatly reduced in cooler temperatures. In order to
fully expand, the open cell foam must utilize heat from the exothermic chemical
reaction created when the two chemicals mix - in essence building off of its
own heat reaction to reach its full expansion potential. The heat reaction is
greater the thicker the foam is applied which helps the expansion. For this
reason, open cell Versi-Foam® kits should never be applied in less than 2"
passes. Even in the warmest temperatures, the open cell product should NEVER be
used in "flash spray" (i.e. less than 2") applications, as yield
will be GREATLY reduced.
systems are best suited for residential roof deck applications (unvented
attics, cathedral ceilings, and garage roofs). Some areas of the country
(particularly Southern Regions) require open cell foam sprayed along the
underside of the roof deck. In the presence of moisture, this low-density foam
will dissipate the moisture quicker than closed cell foam. Open cell foam
should be installed at a 2" thickness for air sealing applications.
is also well suited for exterior wall applications where one inch of closed
cell foam is applied to the exterior sheathing and then filled with open cell
foam. Please note that a vapor retardant would be required on the warm side of
the building envelope when installing closed cell foam in conjunction with low
density foam due to the open cell content.
