What is Froth-Pak?
Froth-Pak is a high-performance spray foam insulation kit designed for fast, effective air sealing and insulation. Manufactured by DuPont, Froth-Pak combines two chemical components to create expanding polyurethane foam that cures within minutes. Ideal for both residential and commercial use, it fills gaps, cracks, and voids — stopping air leakage and improving energy efficiency.
Standard Board-Foot Kits
DOW FROTH-PAK 200 and 600 Board-Foot Kits (1.75 PCF)
Description: These kits are designed to fill larger cavities and voids, providing an effective insulation barrier.
Use Cases: Ideal for big rooms, crawl spaces, or large wall cavities. The primary difference between the 200 and 600 board-foot kits is the coverage area; select the one based on the size of your project.
Class A Board-Foot Kits
DOW FROTH-PAK 200 and 600 Board-Foot Kits, Class A (1.75 PCF)
Description: The Class A designation means these kits meet certain fire resistance standards. They retain all the insulating properties of the standard kits but add an extra layer of fire protection.
Use Cases: These are especially suited for spaces where fire resistance is crucial, such as near furnaces, in basements, or in commercial buildings. Again, choose between the 200 and 600 board-foot kits based on your coverage requirements.
Guidance for Selection
- Size of the Project: Evaluate the scope of your project. If you're insulating a smaller space, the 200 board-foot kit may suffice. For larger areas, the 600 board-foot kit is a better choice.
- Fire Resistance Needs: If your project is in an area where fire safety is paramount, it's recommended to opt for the Class A kits.
- Professional Assistance: If you're unsure about your specific needs, consider consulting with a professional or reaching out to Insulation4US's support team for guidance.
