insulation, air sealing and sound dampening | Jul 12, 2006 |
Commercial construction projects often present challenges to architects and contractors, some involving insulation, air sealing or sound dampening. These issues can be addressed with the use of VERSI-FOAM® portable disposable polyurethane foam dispensing system. In our energy conscious world, one of the key phrases is "Building Envelope," which is the system of components that protects against movement of air, moisture and heat. Polyurethane foam being one of the most efficient insulation materials available, spray applying a layer of VERSI-FOAM® onto the surface will provide excellent insulation in lesser thicknesses than other insulating materials. However, the R-value of the insulation system is no longer the sole factor in energy conservation. Air movement and moisture control must also be taken into consideration. VERSI-FOAM® is an expandable foam that will completely seal any gaps and crevices preventing air infiltration, moisture infiltration, as well as the intrusion of dirt and pollutants from the outdoors. In addition, large gaps and crevices are easily filled using our patented U-Control dispensing gun.

The air barrier system within a "Building Envelope" is a critically important element for economic control for moisture, thermal transfer and preserving structural integrity. An inadequate barrier system will allow leakage of air through holes, leaks, cracks and gaps in the thermal building envelope. The end result is movement of air, moisture and heat. The leaking air carries humidity to the dew point locations within the building envelope, resulting in a growth of black rot or mildew. Another concern today is the rise of energy costs to heat/cool their homes. An inadequate barrier system will allow heat to flow through the home and between its surroundings by conduction, convection and radiation. Simply stating, heat will always flow from hot to cold resulting in increased energy costs within an inadequate barrier system. Interior surfaces in inhabited buildings should be covered with a 15 minute thermal barrier for fire protection. VERSI-FOAM® will contribute to a better performing "Building Envelope."
