Foams make effective gaskets

SuperSheet materials are a low-density urethane foam that effectively resist water and air permeation. The foam's cells require little pressure to compress, yet resist permanent collapse, making them well suited for gaskets.

SuperSheet materials are a low-density urethane foam that effectively resist water and air permeation. The foam’s cells require little pressure to compress, yet resist permanent collapse, making them well suited for gaskets. They are available in four grades, varying by hardness, water resistance, and density; and come in numerous thicknesses.
