foam. It is important to use the foam within a temperature controlled environment, the minimum temperature to which the foam can be installed should be no less than +20°C. If the temperature is below +20°C the foam may show signs of slumping and irregular expansion. Cans should not be left in an over-heated environment, The Slow Rise formula will expand approximately six times its original liquid volume, therefore, the Slow Rise foam is NOT recommended for use in wall cavities where one or more sides of the wall are gypsum wallboard or other material that would not withstand the pressure of the expansion. The Versi-Foam® Slow Rise System is 97% closed-cell and has an insulation R-value of 6.7.
Low expansion foam expands 20-30 times its liquid size and is suitable for quickly filling cracks and small openings (e. For example, when an expansion foam product is said to have the density of "two pounds," that means the foam has a density of "two pounds per cubic feet."
