Open cell spray foam is made of partially closed cells. Since open cell spray foam uses minimal chemicals, it usually costs less than closed cell spray foam. This type is ideal for use in attics and walls during residential renovations and constructions.
Besides not shrinking or settling, open cell spray foam offers some key benefits:
R-values of up to 19
Fast expansion rate
Sound blocking capabilities
Containing a lower air content and more compact cells, closed cell spray foam is denser than open cell spray foam. While closed cell spray foam is effective for various residential applications, it’s designed for use on masonry framing and metal buildings. It better protects indoor spaces from moisture, which causes mold and mildew growth. Like open cell spray foam, closed cell spray foam also doesn’t shrink or settle. Its other primary benefits include:
Higher racking strength
Strong vapor barrier
Inhibits air leaks
Decreases air and noise travel
Keeps out insects
Minimizes mold and mildew growth
