SPF Weatherization Contractors

The responsibilities of and need for spray polyurethane foam (SPF) Weatherization Contractors have grown alongside the value that homeowners and others place on energy efficiency. Professional Weatherization Contractors use their specialized skill set to install a particular kind of SPF called low-pressure, two component foam. It is the type of foam most often sold in kits.

These contractors can also install another type of product, insulating foam sealant, sometimes called one component foam (OCF) or “foam in a can.” (Weatherization Contractors perform a function different than their other SPF contractors who use high-pressure, two component SPF systems.)

Some Benefits of SPF in homes

Increases comfort
Impedes entry of insects and pests where it is applied
Minimizes air infiltration that can generate condensation and result in mold growth
Seals small cracks to help insulate large areas, such as walls and roofs
Resists settling due to its general stability
Can qualify for utility rebates, tax credits and green certification

SPF insulation has grown in popularity because it is good at keeping homes warm in winter and cool in summer.

Because it is sprayed directly into the gaps, cracks and other surfaces that contribute to heat loss, it both insulates and air seals, offering one of the easiest and most effective ways of weatherizing existing homes and new construction.

Among other benefits, it can help save on energy needs, reduce heating and air conditioning equipment size, and reduce drafts and noise. These and other benefits have probably been something that you have been asked to describe to customers.

Weatherization Contractors are in a position to talk about the benefits of SPF and answer questions from customers. Contractors have a responsibility to stay informed about the safe use and handling of SPF products. This site offers information that will help you achieve that. An initiative of the American Chemistry Council’s Center for the Polyurethanes Industry (CPI), this site is designed to help you be a better—and better informed—professional.
