Spray foam insulation

 

Spray foam insulation, or spray polyurethane foam (SPF) insulation, is an alternative to traditional building insulation. It’s a safe, modern material with proven money and energy saving results. It was originally used on military airplanes in the 1940’s but now you can have it in your home.

How does Spray Foam work?

Spray polyurethane foam is basically a chemical reaction that forms a foam which expands and eventually hardens. The mixing materials expand on contact to create foam that insulates, air seals and provides a moisture barrier. For example, if there is space between your roof and attic, head will naturally escape through the uninsulated space. With spray foam insulation installed, the heat stays inside, ultimately saving you warmth and money.

Benefits of Spray Foam Insulation

  • Reduces heating and cooling costs by 25%-45% for the life of your home
  • Improves your home’s energy efficiency by using your HVAC equipment less often thanks to spray foam’s air sealing qualities
  • Reduces the amount of allergens, pollutants and moisture entering your home
  • Keeps you and your family warm in winter and cool in the summer
  • Reduces the risk of drafts or cold spots
  • Minimizes noise from external sources and noise from within your home (such as that forever running plumbing, which we also have you covered for)
  • Adds structural integrity to your home
  • Add resale value to your home

 

Is Spray Foam Insulation Safe?

Spray foam insulation is not only better for your wallet, it’s also better for your health and the environment. Spray foam insulation is made of resins, free of harmful chemicals, and has been shown to reduce the amount of dust and allergens in your home. Unlike spray foam, fiberglass insulation is required to carry a cancer warning label. Fiberglass insulation uses formaldehyde as a binder and also includes other harmful products like VOC’s, CFC’s, HFC’s, and HCFC’s. Fiberglass, rockwool and cellulose insulation all collect dust and allergens and trap them in your home.

 

How is it installed?

Having spray foam insulation installed is no small task, so we highly suggest working with a trained professional spray foam contractor like those at Roscoe Brown. Installing spray foam insulation requires planning and appropriate training, both of which our team ensures. First, we ensure the home or jobsite is prepped to protect from overspray. Our employees then put on their protective equipment and our two part chemical is warmed up to proper temperatures ensuring maximum insulation. The material is then applied using a spray gun, very similar to the process of spray painting a surface. The insulation goes from liquid to foam, is dry to the touch within seconds, and completely cured in 24 hours.

How much money can it save a homeowner?

Spray foam insulation seals against unwanted air infiltration, which is 40 to 50% of home energy loss as determined  by U.S. Department of Energy testing.  It reduces heating and cooling energy consumption and costs by 25% to 45% for the life of your home and allows a 25% to 40% reduction in size of the HVAC system needed for your home.  

 

Spray Foam Insulation vs Fiberglass

 

Spray Foam Insulation

  • Spray Foam Insulation stops air in it’s tracks. Not only does is prevent leakage, it also stops the cold or hot air from coming in.
  • Spray Foam Insulation is a modern material that’s been used for over 30 years.
  • Spray foam insulation expands up to 100 times its original volume, filling every nook and cranny while ensuring maximum insulation for your home.
  • Spray Foam Insulation Protects Your Home From Water.  Many open cell spray foam drains water rather than holding it, and most closed cell spray foam doesn’t let it in at all.
  • Spray foam stays in place – it doesn’t settle or sag, vertically or horizontally. It moves with the house as it settles. Spray foam insulation is completely solid when it sets, doesn’t produce any dust, and doesn’t let dust or other pollutants pass through to your home.
  • Spray Foam Doesn’t Attract Pests.  Many spray foams do not provide a source of food for rodents, termites, or other nasty critters. As a home insulation, spray foam also doesn’t make for good nests.

Fiberglass and Cellulose

  • Fiberglass is an old technology, and cellulose is little more than shredded newspaper.
  • Fiberglass and cellulose are extremely difficult to install perfectly. They typically leave gaps that collectively equal the size of a basketball and leak enough air to fill two blimps a day. Leaving you with excessive heat loss, unwanted cold drafts in the winter, and stuffy warm air in the summer
  • Cellulose and fiberglass are both known to absorb water which can lead to structural damage.  Cellulose is made from shredded newspaper, and drinks up water. Fiberglass batts and cellulose don’t repel water — the water stays in place and may damage your home as well as reduce how well the insulation works. This is one of the leading contributors to mold development — and it also decreases R-values, meaning you spend more on energy.
  • Fiberglass and cellulose settle and sag over time, leaving gaps that compromise insulation. Fiberglass and cellulose can be dusty and allow dust and other pollutants to enter the building.
  • Fiberglass and cellulose can be torn apart by pests, and some even use them for nesting.
