RE: Styrofoam Panel

[Subject Prev][Subject Next][Thread Prev][Thread Next]
First, the material is probably expanded polystyrene, not Styrofoam.
Styrofoam is Dow Chemical's trademark for their extruded polystyrene.

Second, even if the polystyrene foam had enough stiffness and strength to
act as a shear wall (it doesn't), it must be protected.  See, for example
Section 2603 of the IBC.  With the proper thermal barrier, a shear wall
would exist, but it would still require testing.

Without skins of any kind it cannot be a shearwall.

Subject: Styrofoam Panel


I just received a call from a contractor who is remodeling a building and
came across a styrofoam panel that is being used as a shear wall.  He had
never run into something like this and wanted some information about it and
if it could be used as a shear wall.

His description of the panel is:

   4' wide, 8' to 10' long and about 5" - 6" thick.

   A sheet metal channel forms the boundary of the panel.

   There is no plywood or other finish on the surface of the panel.

   There is no material embedded in the styrofoam other than the sheet metal

   channel boundary.

Based on this meager information, does anyone know anything about such a
panel, who manufactured it, and if it was rated for use as a shear wall?

TIA
