Foam is becoming mare popular. Rigid foam boards are workable because of a very high R-value, resistance to water, and air sealing. Spray foam can also be used in a wide variety of ways. Both are good choices for walls.

Rigid foam is best for the basement and the walls in crawl spaces

The R-Value in rigid foam can range from R-4 to over R-6 per inch. This of course depends on the type of foam used to make the panel. Usually the foam board is glued straight onto the foundation wall and the joints are sealed with 1 part spray foam and tape to keep the insulation in a continuous flow. In basements, the local codes for building mandate that a layer of rigid-foam be covered with a fire-proofed wallboard material.

Give new life to your old walls- Injection foam has makeup that will allow it to flow into the wall cavities. It can chilly drafts caused from air leakage, and make your homes envelope a lot more energy efficient.

Injection foam can upgrade insulation levels in wood-frame walls

Most walls that are wood-framed have within them either no insulation or fiberglass insulation that just does not to the job well. Regardless, both your comfort and energy costs can be changed for the better by filling up the wall cavities with injection foam. Injection foam is a distinct kind of spray foam that is made just for using in the building cavities. The foam is water based and is textured like shaving cream. Its texture is meant to flow around things and even the existing insulation. It fills the haps and completely seals air leaks to give a more complete insulation coverage. It will harden after a few minutes and will not shift or compress like fiberglass.
