Understanding Foam Insulation Types
Closed-Cell Foam Insulation
Closed-cell foam insulation is like the haughty, luxury brand of insulation. It’s dense and firm, and the cells are closed tightly, which means it doesn’t absorb moisture and provides high R-values (a measure of thermal resistance). This makes it perfect for areas that might get wet, think basements or exterior walls.
But here’s the kicker, it can be pricey. You’re looking at about $1.00 to $3.00 per board foot (yep, that’s about what you’d pay for that fancy latte at your favorite café). According to the U.S. Department of Energy, it can help you save significantly on heating and cooling costs over time, which is definitely a win.
Open-Cell Foam Insulation
On the flip side, we have open-cell foam insulation. This type resembles a fluffy, less firm marshmallow. The cells are open, allowing air to pass through freely, which gives it a lower R-value (typically around R-3.5 to R-4 per inch). This makes it suitable for interior walls and ceilings, where moisture isn’t as much of a concern.
Not only is it generally cheaper than closed-cell foam (around $0.50 to $1.00 per board foot), but it also expands well, filling in nooks and crannies like a champ. Just keep in mind that if moisture is your enemy, this isn’t your best bet.
