What is Open Cell Spray Foam Insulation?
Open-cell spray foam insulation is a low-density foam that is applied as a liquid and then expands significantly to form a lightweight, spongy material. The “open-cell” structure means the cells are not completely enclosed; they are partially open, which gives the foam its flexibility and makes it less rigid compared to closed-cell spray foam.
-
Upon application, open-cell foam expands to about 100 times its initial volume, filling nooks, crannies, and cavities effectively.
-
The structure of open cell spray foam insulation allows for air and moisture permeability, which helps manage humidity within walls and other enclosed spaces.
-
Open cell spray foam adapts to the shape of the spaces it’s sprayed into, providing a snug fit without adding significant weight.
What’s the difference between Open Cell Spray Foam and Closed Cell Spray Foam?
-
Unlike closed-cell spray foam, open-cell foam has a lower density and a lower R-value (thermal resistance), making it less effective as a thermal insulator but ideal for soundproofing and filling spaces.
-
Open-cell foam remains soft and flexible, allowing for slight movements in the structure, whereas closed-cell foam hardens into a rigid form.
-
Open-cell foam allows moisture vapor to pass through, which helps in reducing potential moisture buildup within the walls but requires careful placement to avoid moisture issues.
