What is considered high density insulation?

“High density” means more fibers per square inch than standard insulation products. That means you get a higher R−value per inch. As with all PINK fiber glass insulation, high density insulation products will not hold water, thereby resisting any permanent loss of R−value.

What is closed cell foam?

Closed cell foam is defined as a cell totally enclosed by its walls and hence not interconnecting with other cells. Closed cell foam is usually made by subjecting a rubber compound to a gas, such as nitrogen, under high pressure. … This type of material is ideal for sealing as it effectively reduces liquid and gas flow.

What is the R-value of high density foam?

Installed insulation R-value: The installed insulation R-value depends somewhat on the system manufacturer but generally speaking, high density foam (2.0 pcf) ranges between R-5.5 and R-6.5 per inch for the aged R-value, and low density foam (0.5pcf) has an R-value of approximately R-3.6/inch.

What is the difference between high and low-density foam?

Foams with a high density will generally feel more firm, and can withstand more pressure. Conversely, low-density foams will feel softer, but cannot withstand excessive pressure or weight.

What is foam density rating?

Foam density is a unit of measurement that dictates how many pounds polyurethane foam can support per cubic foot. In short, foam density tells you the strength of the foam, and that decimal you’re seeing is the number of pounds each cubic foot can hold.
