Spray Foam Insulation FAQ’s



Is Spray Polyurethane Foam Toxic?

Cured polyurethane foam is NOT toxic. However, when the foam is being applied we are basically making a foam plastic and thus, there are hazardous chemicals involved. Within a half hour of application and with proper ventilation there are no hazardous fumes present in the building. After curing it is an inert foam plastic that will last hundreds of years.



Is Spray Polyurethane Foam a Fire Hazard? 

No, Spray Polyurethane Foam is not a fire hazard. About 15% of its components are fire retardants. Its flame spread and smoke developed index are less than 25 and 450, respectively, which are the magic numbers for building code acceptance. If you were to try to light Spray Polyurethane Foam on fire it would simply melt and char. Once you took the flame source away it would self-extinguish. The toxins given off when Spray Polyurethane Foam burns are less than those given off by burning wood.



How can R-19 of Spray Polyurethane Foam outperform R-38 of fiberglass?

R-Value is one of the most misused and misunderstood measurements in the world. The test results are determined in a 75-degree (F) lab with no wind load and ideal humidity. In such conditions the two insulation types are identical with respect to heat transfer. However, once the insulation is installed in a home in real world conditions, the heat loss/gain of fiberglass and cellulose are outrageous since cold and warm air move freely about them through convection. Spray Polyurethane Foam is an air barrier AND it is physically adhered to the wood framing members of a structure thus minimizing air infiltration. Think of fiberglass as a screen and Spray Polyurethane Foam as a window. Coincidentally, most furnace filters are made from fiberglass. These filters are obviously designed to allow the free movement of air through them.



Why would I pay twice as much for Spray Polyurethane Foam when I could just use Fiberglass Instead?

One has to look at the complete cost of something they are putting into their house before making a decision. The cost of insulation is small compared to the ongoing heating and cooling costs of your home after you move in. Since your energy use is cut in half with Spray Polyurethane Foam anyone can do the math and realize that after about five years the cost of insulation, heating fuel, and electricity for cooling is the same for both Spray Polyurethane Foam and fiberglass. After that time your energy savings with Spray Polyurethane Foam will put cash in your pocket every year. The Heating and Cooling load on a home is the gas-mileage of the home forever.



Can my house be “Too Tight”?

Yes it can, but it’s highly unlikely, especially in the windy climates of the southeastern United States. CMU and wood framed homes will always have some small gaps and cracks no matter how well they are framed or insulated. Windows will also have small amounts of air infiltration. Whenever a door is opened to the outside of the home air exchange occurs. Our position is that you only get one chance to insulate a new home. If you under-insulate you will regret it. In the unlikely event that you over-insulate the situation can be remedied with low cost ventilation.



What are the advantages of flexible foam?

Any foam such as Spray Polyurethane Foam that adheres to building materials, must remain flexible in order to maintain its air seal. Buildings expand and contract with changes of season and temperature. If the foam is too rigid, it will inevitably develop cracks along the studs and ultimately the air seal will be destroyed. While other types of non-rigid insulation — such as batts and loose fill cellulose — can slip, sag, or settle, leaving un-insulated gaps.



Is the insulation corrosive to metals?

No. It is non-corrosive, neutral — neither acidic nor alkaline — and ideal for metal construction.



Do I need Attic and Roof Venting?

No. Attic and roof venting were developed because of the inferiority of non-foam insulation. In the winter in northern climates, moisture typically condenses on the interior side of insulation because the interior wall temperatures are relatively cold compared to the warmer air toward the center of the house. The only way to get the moisture out of the house was the creation of ridge and soffit venting. Unfortunately, this also results in the loss of heat. In the summer, venting is typically used to remove hot air from un-insulated attic spaces, one of the purposes of which is to protect the underside of roof shingles from excessive heat. With Spray Polyurethane Foam there are no such problems. The temperature of rooms in the winter is uniform throughout, thus eliminating any chance for condensation to occur. In the summer, the attic is just slightly warmer than the rest of the house, thus there is no potential for roof shingle damage.
