Open-Cell Spray Foam Insulation
What is Open-Cell Spray Foam Insulation?
Open-cell spray foam insulation expands up to 120 times its volume, creating a seamless air seal that stops cold winter drafts and blocks humid summer air in Capital Region homes. Its spongy structure absorbs sound exceptional well, making it ideal for hushing street noise in dense Troy neighborhoods or dampening sound between interior floors. Additionally, its cost-effective R-value per inch makes it an affordable solution for insulating dry attics and interior wall cavities to handle New York's harsh seasonal temperature shifts.
Where Is It Used?
Open-cell spray foam insulation is ideal for dry, above-grade interior spaces where air sealing and sound dampening are the main priorities. It is commonly applied in standard interior and exterior wall cavities, as well as floor joists between stories, to absorb noise and create a quiet, energy-efficient living environment. It is also widely used in unvented attics and roof decks to build a continuous thermal envelope above the home. By expanding up to 120 times its original size, open-cell foam fills tight, hard-to-reach gaps around roof rafters and ceiling framing to eliminate air leaks and keep energy bills down.
