Buying Guide
Choosing the right closed-cell foam insulation depends on your project. Here’s what to consider:
- R-Value: A higher R-value means better insulation. Think about your climate and energy needs.
- Project Size: Small gaps? A can of sealant works. Big project? A two-component kit might be better.

- Cost: Balance your budget with the insulation performance you need.
- Fire Resistance: Check for fire-resistant options, especially for walls and ceilings.
- Moisture Resistance: Closed-cell foam is great for this, but double-check the product specs.
- Application: Consider the application method. Some foams require special equipment.
Consider the application process. Some closed-cell foams need professional installation. Others are DIY-friendly. Read the product details and instructions before you buy.
Ventilation is also important. Ensure proper airflow to prevent moisture problems. This is especially crucial in attics and crawl spaces.
Finally, think about soundproofing. Closed-cell foam can reduce noise transmission. If sound control is a priority, look for foams with high sound transmission class (STC) ratings.
