Attic spray foam using both Open Cell and Closed Cell Spray Foam Insulation, is the only insulation that has the unique ability to create a complete and an effective air barrier that completely air seals your attic preventing hot, humid air from entering your home and keeping cool, conditioned air from escaping your home.

Using spray foam in your attic converts an unusable and unbearly hot environment into a semi-conditioned attic space that drastically reduces attic temperatures from 100+ degrees down to within 5-15 degrees from the rest of your home. Because the temperature differential between the attic and conditioned house is within 5-15 degrees, the potential for condensation is greatly reduced preventing the risk of  mold and mildew from growing in the house and reducing the risk of plywood decay from high moisture issues.

Simply put, spray foam Insulation is effective at keeping conditioned air inside the home and unconditioned air outside the home. This means HVAC units will no longer have to work as hard to keep a house cool which can result in a 20-60% reduction in heating/cooling costs compared to a home insulated with traditional fiberglass or blown-in. Not to mention, there will be less wear-and-tear on your HVAC unit allowing your unit to last longer and work more efficiently than before. A unit that would struggle to reach a temperature set-point before spray foam will now be able to achieve the set-point and stay there without having to run non-stop!

Indoor air quality will also improve by preventing air-borne pollutants, pollen and other allergy-causing particulates from entering the home through your attic vents. We block off all vents going out of your attic which effectively raises the thermal envelope from the floor to the roof rafters allowing the attic to be a semi-conditioned space. Spray foam is also known for its ability to absorb sound when applied to the roof deck and is commonly used in areas with high noise pollution (think airports, highways and railroad tracks).

The most common spray foam product used to insulate attic roof decks is open cell spray foam insulation, sometimes referred to as half pound foam or Icynene (seen in the images on this page). It is important to note that Icynene is a brand name, similar to how a tissue is referred to as Kleenex. While we use Icynene-Lapolla, among other reputable and high-quality products, there are a number of other reputable manufacturers that product high-quality raw materials for spray foam. Companies such as Carlisle, Gaco Western and UPC have produced open cell products that have actually performed better in NFPA 286 AC377 Appendix X fire testing and have GreenGuard certification for Low VOCs, which Icynene does not.

Open cell foam Insulation can range in density from 0.5 lbs per cubic foot to 0.8 lbs per cubic foot and have R-values ranging from 3.6/inch to 4.5/inch. In South Florida, we commonly recommend spraying an R-20 Open Cell which is approximately 5.5" thick. We find this delivers the best bang-for-the-buck as the first few inches of foam do most of the air-sealing work with each additional inch of spray foam experiencing diminishing returns. We do not recommend spraying less than R20 with open cell spray foam as this may lead to issues from a lack of thermal insulation mass. There is also nothing wrong with putting more insulation and are some customers opt to spray R25 or R30 insulation as well!

It is common for open cell spray foam insulation to be installed in above-grade wood-framed walls and roof deck truss or rafters as it has the ability to allow water to pass through in the event of an attic roof leak. Should a sheet or two of plywood need to be replaced, don't fret, we have portable Froth Paks that allow for touch-ups and repairs without the need for a box truck.

Open cell spray foam insulation also does a good job at sound absorption and will create a quieter, more comfortable home than traditional insulation products. Some customers have compared it to the quietness of home after a snow-storm covers the roof of the home with a blanket of snow.

Open Cell spray foam insulation is also the least expensive of the spray foam options available. Open cell Spray Foam Insulation expands over 100 times its liquid form within seconds and excels at filling cavities and voids, tight eaves, as well as unusual framing. It is great for insulating tight areas like where the roof meets the wall at the perimeter of the home.
