Spray Foam Insulation Closed Cell Vs Open Cell

In density whereas closed cell ranges from 1 7 to 3 0 lb cu.

Spray foam insulation closed cell vs open cell.

Open cell foams most commonly range from 5 lb to 7lb densities. Closed cell foam is roughly four times as dense as open cell for insulation applications. Closed cell and open cell spray foam do have different blowing agents. Open cell is lightweight foam that is flexible and an excellent air barrier.

Closed cell foam can also increase the racking strength of attic walls which. Open cell spray foam costs between 0 25 to 0 50 per board foot and closed cell spray foam ranges from 0 90 to 1 50 per board foot. Open cell spray foam insulation cost open cell spray foam insulation costs 0 25 to 0 50 per board foot. When applied on the interior open cell spray insulation provides performance advantages that differ from those of closed cell spray foam used on the exterior.

Closed cell spray foam uses a chemical agent that can give off a temporary odor with some brands. Generally speaking open cell foam is better suited for residential applications specifically above grade in exterior walls roof lines attic floors and areas that need soundproofing. Closed cell spray foam is an incredible product below grade in your basement or crawl space because of its ability to block moisture see below. Closed cell foam is higher density foam and a moisture barrier.

Architectural firms can specify both the building envelope for a total performance option. 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. To ascertain foam density one cubic foot cu. In density or even higher for certain applications.

There are two types of spray foam insulation open cell and closed cell. Open cell tends to be roughly 0 5 lb cu. Open cell spray foam is it typically uses water as its blowing agent. The products we use have minimal off gassing which means less of a smell.

When it comes to insulating a home whether that s a roof insulation or floor insulation it is ideal to use icynene open cell spray foam. This makes the foam a softer more flexable material. Open cell foam is full of cells that aren t completely encapsulated. Open cell foam has an r value of about 3 5 to 3 7 per inch while closed cell foam has an r value of about 6 per inch.

Ft of foam material is weighed. However open cell and closed cell have their different uses. Both icynene open cell and closed cell spray insulation are effective insulators with both working as barriers for air leakage.
