Spray Foam Insulation
A versatile energy-saver. 2-part spray foam expands after it's applied, creating an effective thermal and moisture barrier. Thanks to its unique properties, it can be used to solve comfort & energy problems in your building.
Spray foam insulation has no food value for pests, so it does not support mold, bacteria, or fungal growth. Spray Foam Insulation is safe, non-toxic and can air-seal residential and commercial buildings, schools, offices and more.

✅ Air barrier
Spray foam air-seals and insulates in one step. Its ability to expand and fill gaps and cracks make it an ideal air-sealing material, and it stays in place because of its super-adhesive qualities. Spray foam is often spot-applied as an air-sealing treatment prior to filling an attic with blow-in insulation. But when applied in more generous amounts, it can eliminate the need for other types of insulation.
✅ Waterproof
Moisture will soak its way through fiberglass and cellulose insulation, but polyurethane spray foam stops it cold. Its closed cell structure means that water can't migrate from one tiny cell or bubble to a neighboring one.
✅ Foolproof
Did you know that a void (missing insulation) of just 5% of an insulated area can diminish overall insulation performance by as much as 50%? It's very difficult to install fiberglass insulation perfectly, so voids are not uncommon. But spray foam's expanding, super-sticky characteristics just about eliminate the possibility of voids. And once the foam cures, it's not going to settle or shift like fiberglass or cellulose can.
What is it?
Spray Polyurethane Foam Roofing, or spray foam roofing, is a material that is sprayed as a liquid so it can expand into a foam, creating a solid layer across an existing roof.
Spray foam roofing can be used to solve your commercial building’s toughest challenges, inside and out.
Before the installation can start, the existing roof (or substrate) needs to be prepared. Rather than stripping the existing roof, the contractor will most likely prepare the substrate by getting rid of all dirt, dust, and contaminants. This can be done with air pressure, vacuuming, or even just sweeping.
The first layer is the polyurethane foam. This foam is created by combining two liquids (a polyol/resin and an isocyanate) as it’s sprayed onto the existing roof substrate.
As the liquid is sprayed onto the existing roof, it creates a foam that expands 20 times in size to form a solid, seamless foam surface. When the foam has expanded, this layer is usually between 1 and 1.5 inches in thickness. Since the polyurethane foam adheres to most common surfaces, it can be installed on any roof slope.
When the SPF layer has been completed, it is then coated with a layer(s) of elastomeric silicone or acrylic coating with embedded granules. This layer is generally between 20 and 30 mils (a mil is a thousandth of an inch — .001 inch.) in thickness. The coating protects the roof and SPF from UV light, weather, normal wear and provides the required fire ratings.
✅ Easy Installation
You can save time and money with your new SPF roof. The application of the foam and coating is quick and can be applied with usually no interruption to the daily routine of the facility.
✅ Energy Efficient
SPF roofing delivers thermal, air, and moisture barriers to provide the highest R-value per inch, which means the material provides better insulation for the building.
The polyurethane foam keeps heat out in the summer and in during the winter, lowering energy costs for facility owners. The silicone top coating resists UV light, protecting the foam and reduces heat absorption (emissivity).
✅ Easy Maintenance
Once an SPF roof is installed, it requires minimal upkeep. If properly maintained, your SPF roof can last over 50 years. SPF roofing systems should be inspected semi-annually, in the Spring and again in the Fall. Additional inspections are also suggested following any event that might have caused damage to the system. In the event where a silicone recoating is needed, there’s no tear-off of the existing materials; you apply the new coat on top of the current system.
✅ Seamless and Waterproof
Seams and penetrations are the primary sources of leaks in roof systems, SPF eliminates this vulnerability. Since the SPF mixture is applied as a liquid, it can fill gaps, seams, and cracks in the existing roof and substrate.
The application of the polyurethane foam allows the contractor to level out the roof to decrease the chance of ponding water. The foam material can expand and contract with the building in accordance with outside temperatures, reducing the likelihood of cracks and splitting.
✅ Renewable and Sustainable Roofing
SPF roofs create little to no waste during its lifetime. In most cases, there is minimal stripping of the original roof, and the SPF roof is installed on top – eliminating the need for costly roof tear-offs and waste.
The materials that are used for SPF roofing systems are also environmentally friendly:
