Spray Foam Insulation: The Hero of Cool Summers and Low Electric Bills

Monday March 23, 2015

Is there a better feeling than opening your front door on a swampy Southern summer day and stepping into a cool foyer? What about spending a toasty winter evening curled up on the couch, no fire needed, watching a movie as the winter winds whip away outside? Well, meet the unsung hero of your new home’s cozy winter evenings and cool summer days: spray foam insulation.

As part of the Lamar Smith Signature Home BEST House standard of excellence, all of our new homes include the latest and greatest in energy saving: spray foam insulation (along with Low-E windows and an ENERGY STAR certification). Spray foam insulation is a modern alternative to traditional building insulation such as fiberglass. A two-component mixture melds at the tip of a gun, and forms expanding foam that can be sprayed onto roof tiles, slabs, into wall spaces, or through holes drilled into a finished wall. We admit, there’s nothing flashy or fancy about it. After all, it’s insulation. Yet many people don’t realize the incredible benefits that spray foam insulation guarantees for their home and their families.

The Benefits of Spray Foam Insulation in your New Home

The spray foam stops the heated or cooled air from escaping your home. It works like a warm windbreaker, keeping the undesirable hot or cold air out and keeping the inside of your home the perfect temperature. In contrast, the traditional fiberglass and cellulose insulation operate a lot like a wool sweater. While thoroughly knit and quite bulky, it lets both cold and warm air pass in and out through the openings, causing the lose-lose situation of both higher heating and cooling bills.

Traditional insulation can never be perfectly installed; there will always be spaces and gaps. A one-foot gap in your insulation can lead to enough air leakage everyday to fill up an air blimp. Spray foam insulation expands up to 100 times its original size, ensuring that every nook and cranny of your home’s outer shell is completely optimized for thermal insulation and air sealing.

At one point or another we’ve all seen the end result of 10-year-old traditional insulation: pink or white pillows of insulation strewn across attic floorboards or falling out of the wall in a crawl space. Spray foam insulation stays snugly in place and will never settle, sag or change positions over time, ensuring the incredible insulation you become accustomed to will last for the life of your home.

While traditional fiberglass and cellulose insulation often absorb water particles and overtime become an attractive environment for ants, rats and other pests (many even use traditional insulation for nesting purposes), spray foam insulation’s material offers no appeal for pests, rodents or termites.

And finally, the be-all-end-all reason spray foam insulation is your home’s unsung superhero: air-quality protection! In the Southeast especially, we all are concerned with allergens, pollens, and dust that floats naturally in the air. Spray foam’s air sealant qualities drastically reduces the amount of airborne pollutants your family is exposed to, helping protect them for a lifetime of better health. Traditional insulation can actually trap dirt and allergens as well as serve as a hot spot for contamination and mold growth.
