I’m a Do-It-Yourselfer Installing Spray Polyurethane Foam (SPF)

Do-It-Yourself (DIY) projects you can tackle around the home can include small weatherization jobs using a convenient insulating foam sealant product in an easy to use, small can (typically 12-24 oz.).

Insulating foam sealants (also known as “foam in a can” or “one-component foam”) are a type of spray polyurethane foam product and are readily available at home improvement stores for DIY use. These products are intended for use in a “bead type” application for air sealing or adhering. Their small volume, ease of use, and portability make them ideal for smaller projects, such as sealing gaps and crevices.

Why select insulating foam sealant? It can...

• Help save on energy bills
• Reduce drafts, noise and increase comfort
