How To Choose The Right Spray Foam For Your Project
R-Value
All insulation is identified and labeled by R-value with “R” standing for resistance to heat flow. Basically, R-value is a measure of thermal resistance, or the ability to prevent the transfer of heat. The larger the number, the harder that insulation is working at preventing heat conduction. The less heat loss, the lower your energy bills.
Coverage
Coverage refers to the area in which the insulation is able to cover. Coverage is usually measured in board feet or cubic feet. One board foot is one square foot at 1" thick. One board foot can be converted to cubic feet by being multiplied by .083.
Open/Closed Cell
Closed cell foams consist of trapped gas bubbles formed during the foam’s expansion and cure. These gas bubbles consist are permanently locked into place during the curing of the foam, increasing the foam's insulation capability. The foam’s strength and its closed cell nature enable it to resist liquid water and humidity. Open cells, on the other hand, are released to the atmosphere during foam expansion and curing. By creating “holes” in the cell walls, they are able to interlock and interconnect and they spaces are filled with atmospheric air. Due to its porous nature, open cell foam does not resist liquid water or humidity. Open cell foams tend to not be as strong are less dense than closed cell foams.
Quick Cure
Quick Cure foams are high performance, single component, moisture curing, Class 1 fire retardant, expanding polyurethane sealants. Use Quick Cure Polyurethane Foam Sealants to permanently air seal and insulate gaps and cracks to block drafts, moisture and insects while improving comfort and reducing energy usage in commercial, industrial, agricultural and residential applications. Common applications include sealing around plumbing, ventilation outlets, electrical junctions, between sill plates and concrete slabs, or anywhere requiring a fast, economical air-sealing moisture barrier. Quick Cure foams work on wood, masonry, insulating foam boards, metal, wire insulation, plastics and sheetrock and are available in both straw dispensed aerosol cans and larger cylinders with hoses and applicators.
