đź’Ąđź’Ą Did you know.. there are different types of spray foam insulation you can choose from? Here is a little info to help you make the best decision when choosing insulation. đź’Ąđź’Ą
OPEN AND CLOSED CELL
A spray insulation is referred to open cell or closed cell because of the difference between the small bubbles (cells) that make up the foam.
❌ OPEN CELL foam is full of cells that aren’t completely encapsulated. In other words, the cells are deliberatly left open. This makes the foam a softer, more flexable material.
- BENEFITS of Open Cell Foam -
One of the biggest benefits of open cell foam is that it expands so much after it has been applied, meaning it can insulate hard to reach nooks and crannies in a home. These types of areas can be hard to insulate with closed cell foam. Open cell foam is excellent for soundproofing where a single application can completly fill the area between studs.
Open cell foam is also much more affordable than closed cell foam, however this foam won’t insulate a house as well as closed cell foam, so it’s not ideal for locations with extreme weather temperatures
________________________________________
❌ CLOSED CELL foam is made up of cells that are, as the name suggests, completely closed. The cells are pressed together, so air and mositure are unable to get inside the foam. Because of this, closed cell foam is much more rigid and stable than open cell foam.
-BENEFITS of Closed Cell Foam-
Closed cell foam is the best choice for robust insulating where space is an issue, as it can achieve 2x the R-Value of open cell inside a standard wall. Its rigid nature also adds to the structural integrity. The closed cell also acts as a v***r barrier, so water and moisture will be less likely to get inside the home, and the foam itself is unharmed by water damage.
