Sealing gaps in your home’s exterior is inherently environmentally friendly, but Soy Seal makes it even greener.

Soy Seal is a soy-based spray insulating foam that seals cracks and gaps, reducing heat loss and saving energy. Most insulating foams are petroleum-based.

Now available is Soy Seal for Gaps & Cracks, an expanding closed-cell foam. Soy Seal for Windows & Doors, a low-pressure foam formulated to prevent damage or bowing to windows and doors, is expected to be available in the spring.

Soy Seal has a suggested retail price of $4.96. It’s available at Home Depot stores, according to the manufacturer.
