Open-cell spray foam expands significantly when applied, it creates an effective air seal in spaces where traditional insulation often falls short. Open-cell foam is less dense than closed-cell foam and has a soft, spongy texture.
Benefits of Open-Cell Spray Foam
- Lower Cost – Open-cell foam costs less to produce and expands more, meaning it can cover larger areas with less material, making it a more affordable option.
- Water-Resistant – While not waterproof like closed-cell foam, open-cell spray foam retains less than 5% water and can dry out when exposed to moisture.
- Excellent Insulator – Effectively seals gaps and hard-to-reach areas, offering a higher R-value than fiberglass insulation.
- Energy Savings – Helps reduce heating and cooling costs by minimizing air leaks and improving efficiency.
- Sound Dampening – Its thickness and density make it an excellent sound barrier, reducing noise transfer between rooms and from outside.
