Open cell insulation is a lightweight spray foam that expands to fill gaps and hard-to-reach areas in walls, attics, and ceilings. Its breathable structure makes it ideal for improving airflow and soundproofing while still providing solid thermal insulation. This type of foam is perfect for areas where moisture is not a major issue and is often chosen for interior applications where comfort and quiet are priorities.

In addition to temperature regulation, open cell insulation enhances your home's energy efficiency by sealing cracks and reducing air leaks—helping your HVAC system work more efficiently and lowering utility bills. As a more affordable alternative to closed cell foam, it’s a cost-effective choice for homeowners who want to improve insulation without compromising performance or sustainability.
