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.

There are two types of spray foam insulation open cell and closed cell. 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. Open cell tends to be roughly 0 5 lb cu. Spray foam is categorized into two types open cell or closed cell.

However open cell and closed cell have their different uses. Open cell foams most commonly range from 5 lb to 7lb densities. Open cell spray foam insulation cost open cell spray foam insulation costs 0 25 to 0 50 per board foot. To ascertain foam density one cubic foot cu.

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. 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. Closed cell foam is higher density foam and a moisture barrier. Closed cell foam can also increase the racking strength of attic walls which.

Architectural firms can specify both the building envelope for a total performance option. 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. Both icynene open cell and closed cell spray insulation are effective insulators with both working as barriers for air leakage. 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.

This makes the foam a softer more flexable material. Ft of foam material is weighed. Open cell is lightweight foam that is flexible and an excellent air barrier. Open cell spray foam is it typically uses water as its blowing agent.

Open cell foam is full of cells that aren t completely encapsulated. 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. Closed cell spray foam exterior applications. Closed cell foam is roughly four times as dense as open cell for insulation applications.

Closed cell spray foam uses a chemical agent that can give off a temporary odor with some brands. In other words the cells are deliberatly left open. The products we use have minimal off gassing which means less of a smell.
