Versi-Foam® open cell foam kits have a density of approximately 0.75 lb/cu-ft. It is 92% open cell and has an insulation R-value of 4, lower than the other Versi-Foam® systems, but still superior to some of the other commonly used insulation materials. The appeal of this product is it's high expansion rate. Less foam is needed during application which makes it more cost effective. Open cell Versi-Foam® kits are particularly dependent on temperature. The yield of open cell products will be greatly reduced in cooler temperatures. In order to fully expand, the open cell foam must utilize heat from the exothermic chemical reaction created when the two chemicals mix in essence building off of its own heat reaction to reach its full expansion potential. The heat reaction is greater the thicker the foam is applied which helps the expansion. For this reason, open cell Versi-Foam® kits should never be applied in less than 2 in passes. Even in the warmest temperatures, the open cell product should never be used in "flash spray" (i.e. less than 2 in) applications, as yield will be greatly reduced. These systems are best suited for residential roof deck applications (unvented attics, cathedral ceilings and garage roofs). Some areas of the country (particularly southern regions) require open cell foam sprayed along the underside of the roof deck. In the presence of moisture, this low density foam will dissipate the moisture quicker than closed cell foam. Open cell foam should be installed at a 2 in thickness for air sealing applications. It is also well-suited for exterior wall applications where one inch of closed cell foam is applied to the exterior sheathing and then filled with open cell foam. Please note that a vapor retardant would be required on the warm side of the building envelope when installing closed cell foam in conjunction with low density foam due to the open cell content. Packaged in one carton and includes the two chemical components, our patented U-control dispensing gun attached to two 10 ft hoses, ten extended mixing nozzles, three fan tips and nitrile gloves. Will produce 380 board ft of cured foam or 31 cu-ft at a 1 in Thick. Class I (flame-retardant) formula.
