(1) The theoretical yield has become an industry standard for identifying certain sizes of two-component
kits. Theoretical yield calculations are performed in perfect laboratory conditions, without taking into
account the loss of blowing agent or the variations in application methods and types.

(1) Tested at 2" thickness, full coverage.
(2) This numerical flame spread rating is not intended to reflect hazards presented by this or any other
material under actual fire conditions.
(3) R means resistance to heat flow. The higher the R-value, the greater the insulating power.
