The major application for Spray Polyurethane Foam commonly known as SPF in the construction industry is as a commercial roofing and perimeter wall insulation. Spray Foam Insulation is a closed-cell roofing material formed by combining two liquid components. When these two materials meet in the mixing gun, they expand 20 to 30 times their volume immediately, forming rigid polyurethane foam. Spray Foam Insulation is the best and most advanced insulating material available for your home. It protects your family from airborne hazards, often lasts for the life of the structure, and saves you money in multiple ways. Make sure your new home has been insulated properly and up to date, with spray foam insulation. Due to the expanding nature of spray foam insulation application, your home will be sealed against dangerous pollutants, molds and mildews, even airborne pollutants and allergens. Other types of rolled or blown insulation can’t guarantee a seal like spray foam (SPF) insulation. This seal is essential to containing and isolating your internal climate, increasing system efficiency and lowering costs. SPF insulation can save you money on costly energy bills, reduce the chances of mold and mildew intrusion, and form a thermal barrier seal without extra cost. This same sealing effect means that additional vapor protection or building wrap is often unnecessary, saving further money. A reduced chance of moisture entry and build-up means you’ll spend less money on expensive mold and mildew removal and repair, and spend more time enjoying your home is sprayed on the entire roof to the desired thickness, usually 1-2 inches, to form a seamless monolithic surface including flashing, penetrations and parapet walls. SPF has an initial R-value of 7.14 per inch thickness. This provides more thermal resistance with less material than any other type of roofing insulation. This eliminates seams and cold joints, the primary source of major leaks, and provides a durable waterproof covering that bonds tightly to nearly any properly prepared surface. The lightweight application (about 8 ounces per square foot) can be applied over most existing roof structures. Since it can be applied directly over asphalt, shingles, built up roofs, clay, concrete, metal and wood there is little to no need for tear-off, reducing the amount of time, disruption to the business.
