There are three aspects of conventional foam
which can be optimized:
1. Conventional flat backed wedge and convoluted foams are applied
directly to the mounting surface, where the particle velocity
is zero. Since no absorption can occur when the particle velocity
is zero, a significant portion of solid foam is wasted.
2. To provide appropriate absorption coefficients, conventional
foam is sold in several thicknesses. If an application requires
additional absorption at a later date, the existing foam must
be removed and a panel of greater thickness applied.
3. Conventional foam has limited interior design application because
of its industrial appearance and potential safety
To solve these problems, RPG® patented ProFoam,
the first nestable, Variable Depth Air Cavity (VDAC) foam.
ProFoam uses an innovative, attractive, and universal
profile to space most of the foam away from the surface for
optimum absorption. Since ProFoam is nestable, one size
fits all applications.
Unlike conventional foam, additional absorption can be achieved
at a later date by simply adding additional nestable layers
to form a VDAC Stack. ProFoams unique attractive
shape allows it to be used as a design element. When formed
from fire safe Melaflex, ProFoam can be used in
all spaces that require Class A interior finish treatment.
VDAC technology provides minimum point of contact with
the mounting surface, thus enabling most of the foam to be positioned
away from the wall for optimum absorption. Unlike conventional
foams which are applied in a fixed thickness, additional absorption
can be achieved by simply stacking new layers on top of the
One universal profile fits all applications. Begin economically
and upgrade performance as needed. Nestable profile can be layered
to any thickness offering unlimited absorption at any time.
Can be applied in vertical and horizontal combinations. Can
be cut into various width strips to fill required area. ProFoam
complies with all interior finish Class A fire safety codes.
New modern look allows use as an interior design element. VDAC
technology allows optimum performance at the lowest prices.
