About Closed Cell Foam Insulation

The closed-cell spray foam insulation used by A-1 Advanced, is a 2.0lb. medium density polyurethane foam insulation.  Closed cell insulation foam can be installed in residential and commercial structures, providing a superior thermal, air and vapor barrier.

How We Use the Product

Closed cell insulation foam delivers greater R-value per inch over open cell.  It also, significantly hinders the air infiltration into and out of the structure.  Most energy costs occur from the interior air leaking out of the structure and exterior air leaking in.  Insulation foam is spray applied onto the substrate as a liquid, it then reacts and expands to create foam.  During the reaction and expansion process the foam fills the air gaps that traditional insulation products cannot.  This creates a thermal envelope and air barrier around the structure being insulated. Closed cell foam insulation is used in new construction, remodels and upgrades.  It is commonly applied in:

  • Interior walls
  • Exterior walls
  • Vented attics
  • Unvented attics
  • Ceilings
  • Between floors
  • Under floors

Benefits of Closed Cell Foam Insulation

Closed cell insulation foam is much more durable (due to its density), when compared to open cell insulation foam.  When closed cell foam insulation is properly installed, it will quickly expand into any air infiltration areas, such as, penetrations, cracks, crevices and gaps. Open cell will conform to irregular curves, spaces and surfaces; providing a superior thermal barrier around the entire structure. As the foam controls air infiltration, you will experience a consistent comfort in your building- no more hot and cold zones. Less air infiltration means that pollutants, dust, allergens, etc. will not be able to enter the structure.  Once installed, the foam will not sag or settle over the lifetime of the building. Also, the foam will not support the growth of mold or mildew. Finally, you will increase the structural integrity with the closed-cell foam.

    Larry Kerkow - Larry Kerkow & Associates

  • "Our new Bayseal roof has done a fantastic job insulating and stopping leaks. Before the Bayseal System, my HVAC unit never cycled in the summer; the second story space couldn't be used because it was too hot. Now, the second story rooms are comfortable and the HVAC units cycle normally, even on the hottest days. This SPF roof system has performed beyond my expectations!"

    Gerry Hoerster - Acrotex Gymnastics

  • "It has been my pleasure to work with A1 Advanced Coating and Foam Company. They are a commercial company but also attend to residential needs. I've had 3 roof over the last 15 years and finally found a company who knows what they're doing and did a wonderful job. Very professional, timely and cleanup is amazing. They have fixed my flat roof that no one else could do. I am a REALTOR and will tell all my clients about A1 Advanced Coating. Hollis and Chris are the best guys. Give them a call, you'll be glad you did."

    Barbara Preston - Casa Blanca Realty

  • We first hired A-1 Advanced Coating & Foam Co. about 12 years ago, at our original location. We had Hollis and his crew insulate and coat only half of the building. We immediately could tell the difference in the temperature inside the building. We liked this type of roofing so much; we had A-1 Advanced Coating & Foam Co. insulate and coat all the buildings at our new location. Our employees are able to work comfortably though out the year. This type of roofing requires little to no maintenance - the roof takes care of itself.

    Anthony Heye - Owner, Planet Pickup

  • “We have been in the business for over 45 years and have used many companies to insulate and roof our real estate properties. A1 Advanced Coating and Foam Co. has, by far, provided the best product and service we have received. What I appreciate most is the fact that one of the owners has been on each and every one of the many projects they have done for us over the years. If you want it done right, and at a competitive price, you won’t find a better choice than A1 Advanced! “
