Spray Foam Insulation Closed Cell Vs Open Cell

Closed cell spray foam uses a chemical agent that can give off a temporary odor with some brands.

Spray foam insulation closed cell vs open cell.

Ft of foam material is weighed. There are two types of spray foam insulation open cell and closed cell. Open cell foam is full of cells that aren t completely encapsulated. 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.

To ascertain foam density one cubic foot cu. In other words the cells are deliberatly left open. Open cell tends to be roughly 0 5 lb cu. Open cell is lightweight foam that is flexible and an excellent air barrier.

Closed cell and open cell spray foam do have different blowing agents. Closed cell foam is higher density foam and a moisture barrier. Open cell foams most commonly range from 5 lb to 7lb densities. This makes the foam a softer more flexable material.

Closed cell spray foam exterior applications. However open cell and closed cell have their different uses. 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. 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 roughly four times as dense as open cell for insulation applications. Open cell spray foam is it typically uses water as its blowing agent. Architectural firms can specify both the building envelope for a total performance option. 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. 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. Spray foam is categorized into two types open cell or closed cell. In density or even higher for certain applications.

Closed cell foam can also increase the racking strength of attic walls which. In density whereas closed cell ranges from 1 7 to 3 0 lb cu. Both icynene open cell and closed cell spray insulation are effective insulators with both working as barriers for air leakage.
