Accufoam 1.7# HFC Closed Cell Foam
 

Accufoam Closed Cell Foam is a two-component, one-by-one-by-volume spray-applied polyurethane foam. Accufoam Closed Cell Foam is a high-yield, medium-density, spray-applied insulation foam, and is designed to provide good thermal performance and a significant control of air infiltration of an air-barrier assembly.

Advantages of open cells:

• Waterproof
• Highly durable
• Heat insulated 
• Tear resistant
• Forms an airtight seal 
• Has a longer lifespan 

Closed-cell foam can be used outdoors on the exterior of buildings or vehicles. Additionally, it provides some structural support to the application because most of them are firm and don't tear easily. But, there are exceptions to the rule.
