Closed-Cell Spray Foam Reduces Waste While Increasing Savings!

Like open-cell spray foam, closed-cell foam expands to fill gaps and cracks as soon as it’s applied. So what’s the difference? While open-cell becomes sponge-like, allowing the passage of moisture, closed-cell spray foam cures to a hard, smooth-surface mass. In other words, nothing gets past closed-cell spray foam.

Where Should I Use Closed-Cell Spray Foam Insulation?

You may not be aware of the problems lurking beneath your home, but if you’re one of the hundreds of Louisianans with raised cottages, you should take closer look at your crawl space. Moisture from the soil easily seeps into the beautiful hardwood floors that we love, rotting them and making them vulnerable to attacks from termites and mold. Cracks between floorboards and joints allow the passage of air, which means cool air is forced out in the summer and sucked in during the winter.

At up to R-6.8 per inch, the closed-cell spray foam insulation R-value is the highest of any material available. Its air-tight seal decreases air loss, moisture buildup, and termite damage. It also strengthens the structure of the home significantly where applied. This makes closed-cell spray foam ideal for sealing crawl spaces and other outdoor environments.
