Why Do R-values Differ in Foam Board Products?
Since foam board comes in different variations with different compositions, each product has its own effectiveness in preventing heat energy loss. For instance, expanded polystyrene has a lower density and lighter mass. This means it has a lower R-value per inch as compared to other forms of foam board, such as polyurethane. Nonetheless, all of these types count as foam board and bring significant insulation properties to the table.
How Long Does Foam Board Insulation Last?
What good is an insulation that requires replacement after every couple of years? Foam board insulation is one of the most solid solutions out there that provides a durable barrier against the weather. Its closed-cell forms have a long life due to their high-density composition. Not to mention foam board’s resistance towards moisture, which is one of the key reasons behind insulation going bad before its due time. You can expect the R-value to remain constant as well because rigid board does not deteriorate with time. Therefore, durability is the last thing you need to worry about if you’re opting for foam board insulation.
