FoamLok 500 (FL500) is a half pound density open cell foam that creates an air seal undetectable by human senses. FL500 is a 2-part spray applied polyurethane cellular foam plastic.  The product is sprayed on as a liquid, expands, and cures within minutes.  The major differences between FL500 open cell foam and FL2000 closed cell foam are as follows:

• Aged R-value of 3.9 per inch of depth (closed cell is 6.2 (aged) per inch)
• Vapor Barrier (Open Cell is not a vapor barrier)
• Structural (open cell foam is soft like angel food cake; closed cell is a little softer than wood)
• Less Expensive (more materials are needed to produce an "R" of Closed Cell)

Although FL500 is suitable for almost any use, our typical installs of this product include:

• Residential homes
• Areas where space is not an issue (i.e. attics - new and existing)
• Sound attenuation
• Closed walls
