When it comes time to insulate a home or commercial building, you must choose between open-cell foam and closed-cell foam. Each type of foam distinctly impacts project costs, application methods, and building performance. There are two major factors distinguishing closed-cell and open-cell foams: structure and density.
The structure of open-cell foam consists of tiny bubbles or cells that aren’t fully encapsulated–they are broken, torn, ripped, etc. Because they’re broken, air fills the open space inside the bubble, which results in a soft, spongy material. Closed-cell foam differs in that every bubble or cell that makes up the foam is completely encapsulated and packed tightly together. The bubbles aren’t filled with air, but with a gas that aids foam expansion and insulation properties. This results in an altogether harder, stronger material than open-cell foam.
The blowing agent, which aids in forming the bubbles or cells that make up SPF’s foam structure, is usually water for open-cell and high-R-value chemicals for closed-cell.
Closed-cell foam is roughly four times as dense as open-cell for insulation applications. To ascertain foam density, one cu. ft. of foam material is weighed. Open-cell tends to be roughly 0.5 lb./cu. ft. in density, whereas closed-cell ranges from 1.7 to 3.0 lb./cu. ft. in density, or even higher for certain applications. (Note: these density figures are rough averages. Every SPF product will vary based on its formulation.)
Need more insulation blown up in my attic. They showed up on Tuesday at 7:30am, no standing around, all business, very professional, cleaned up and gone by 11am. Couldn't even tell they had been there. I highly recommend this business. Great group of guys. If I ever need this type of service again, I will contact T&M Sprayfoam & Insulation
T & M provide excellent service for an excellent price. They spray foamed my grandfathers crawl space and it is amazing. It is completely sealed and makes his home so much more efficient, not to mention how much cleaner it is not to get under there with the plastic liner. Once I saw what they did on the crawl space I knew these guys were professionals so when I had a piece of my side walk at work that had sunken to the point that it was a tripping hazard I knew just who to call. They came out, drilled two holes in the sidewalk and leveled it right out. Saved us a ton of money because otherwise we would have had the concrete removed, re-poured and then we would be left with a big bill and two different shades of sidewalk.
I recently finished my basement. I had the walls sprayed before I installed the drywall. The temperature and humidity is very consistent all year around. I also had them blow more insulation in my attic and my electric bill has dropped considerably. In 2 years time, the savings will pay for the insulation work. Very professional crew.
Chuck was my contact with them. He was easy to work with; professional at his job; on time; also considerate of my wants and needs for the job. He & his helpers did an excellent job on blowing insulation in my home and were very through at cleaning up when finished. They did an excellent job, I would highly recommend them and price was very reasonable. Good People!
Very knowledgeable on what he does and did an excellent job. Cleaned up and was very detailed on the project and I would definitely recommended him to others.
