Cavity Fill / Slow Rise Closed Cell Spray Foam Insulation Kits

HandiFoam® Slow Rise HFO Spray Foam Insulation is an innovative solution for filling and insulating larger cavities. Designed for ease of use, these kits are available in 41ft³ and 12ft³ sizes to accommodate various project needs. The foam is dispensed using the patented Handi-Gun™ dispensing unit, ensuring accurate and precise applications. This closed cell polyurethane foam provides superior insulation by creating a continuous air barrier that completes the building envelope, significantly improving indoor air quality and reducing energy consumption.

Product Features and Specifications

Our HandiFoam® Slow Rise HFO Spray Foam Insulation kits offer a range of impressive features and specifications. The foam cures slowly, allowing for easy application in larger cavities. Key features include a cured volume of 41ft³ or 12ft³, a tack-free time of 60-90 seconds, and a cuttable time of 5-10 minutes. The foam is made from polyurethane, has a fire rating of Class 2 (ASTM E-84), and a density of 2.0 lbs/ft³. With an R-Value of 5.9 per inch, it provides excellent thermal insulation. The closed cell structure ensures a high level of compressive strength at 12psi, making it suitable for various applications.

Installation Tips and Practical Uses

Installing HandiFoam® Slow Rise HFO Spray Foam Insulation is straightforward and can be done by anyone with basic DIY skills. It is important to maintain the core temperature of the tanks between 75-85°F for optimal performance. To change nozzles after stopping spraying for more than 30 seconds is crucial to prevent damage to the spray gun. The foam can be cleaned up with Handi-Cleaner, and once fully cured, it can be removed by mechanical means. This spray foam is ideal for filling wall cavities, sealing gaps, and creating insulation in attics, crawl spaces, and other areas where a continuous air barrier is needed. By using this product, you can achieve ENERGY STAR™ rating and/or LEED credits, contributing to a more energy-efficient and environmentally friendly home.
