RHH Foam Systems Inc is now packaging open cell polyurethane foam in an easy-to-use disposable foam dispensing system.
The Versi-Foam System 100 joins the Versi-Foam product line as a low-density 0.75 lbs/ft3 foam. Until now open cell foams typically have been applied by contractors through commercial equipment. Packaging in portable and disposal dispensing units eliminates the need for an investment in equipment and specialised training and allows for easier operation and clean up. The appeal for low-density, open cell foam is its high expansion rate. Less foam is needed during application which makes it more cost effective.
The Versi-Foam System 100 yields approximately 1,200 board feet. It meets the ASTM E84 Class I testing with a flame spread of 20 and a smoke development rating of 250. The open cell content is 92 per cent and closed cell content is 8 per cent (ASTM D-2856). The R-factor is 3.95 per inch and the K-factor is 0.253 (ASTM C-518). The System 100 features many of the same benefits as the other Versi-Foam products – fast cure times, high yields, quality dispensing, and easy to use.
“The System 100 will provide users a co-effective means to insulate, control air movement and reduce sound transmission between rooms within the building,” says Mark Wojtiuk, general manager at RHH Foam Systems Inc.
The System 100 is best suited for residential roof deck applications (unvented attics, cathedral ceilings and garage roofs). Some areas of the country (particularly in the southern regions) require open cell foam sprayed along the underside of the roof deck. In the presence of moisture, open cell foam will dissipate the moisture quicker than closed cell foam.
The System 100 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. A vapour retardant would be required on the warm side of the building envelope when installing closed cell foam in conjunction with open cell foam due to the open cell content.
This product is not recommended in a “hybrid” insulation application where the open cell foam is used in conjunction with other insulation products (ie fiberglass batt or cellulose). Closed cell foam should be used in a “hybrid” insulation application.
