Abstract

A process for cost-effectively and rapidly insulating a desired surface with spray foam insulation is described which includes the application of a polyurethane foam dispensed through heated conduits into a dispensing gun having a nozzle with essentially planar divergent lips having a triangular prism opening, the lips of the nozzle diverging at an angle of between about 5 and 35° inclusive, more preferably between 8 to 15° inclusive, most preferably 10 to 12° inclusive, thereby achieving application rates which are in excess of 70 Ft2 / min, and optimally in excess of 100 Ft2 / min.

Description

TECHNICAL FIELD

[0001] This invention relates generally to a method of rapidly insulating a desired surface using a polyurethane froth foam for in-situ application of two-component polyurethane foam, and more specifically to a method of using a foam application gun with a two-component polyurethane foam insulation to rapidly insulate surfaces under all weather conditions including temperatures as low as 20° F. BACKGROUND OF THE INVENTION

[0002] There are numerous applications in which spray polyurethane foam is used at a site for any number of applications in, but the most traditional use in the building trades is as a source of insulation. The Department of Energy reports that every year the average home wastes up to 40% of the energy used for heating and cooling as air moves through gaps, penetrations, and cracks in the exterior shell of the house, also known as the building envelope. Spray foam insulation is gaining in popularity because of its many benefits over conventional fib...
