What is spray foam?
Spray foam (polyurethane foam insulation) is a 2 part system consisting of two liquid chemicals, isocyanate and resin, which are pumped through a specialized heating and pressurizing machine for application. The two chemicals are separate until just before they leave the foam gun where they are mixed at a specific temperature and pressure. The combined chemical reaction of the two materials creates an exothermic reaction which causes the material to expand and seal all cracks and crevices.
What is R Value?
R-value measures the thermal resistance of a material.
What is the difference between open cell and closed cell foam?
There are two types of foam available for application, 0.5lb foam which is an open-cell foam and 2lb foam which is a closed-cell foam. In open-cell foam such as 0.5lb, the cells of the foam are not completely closed. The cells are broken, and air fills all of the “open” space inside of the material. This makes the foam weaker and softer feeling than closed-cell foam. 2lb foam is a closed-cell foam, where all of the foam cells are closed and packed together. Advantages of closed-cell foam compared to open-cell foam include increased strength, higher R-value and greater resistance to leakage of air and water vapor.
Does foam off gas?
All manufacturers’ materials will off-gas to some extent. During application the area will require venting. As soon as those off-gasses leave the room, the foam is completely safe and there is no off-gassing of the foam after the initial application. The application area may require 1-24 hours depending on the project. Steve’s Urethane staff will review your project with you to ensure that your project will be done as safely as possible. All materials used by Steve’s Urethane are tested and approved meeting building code requirements and conditions for safe occupancy.
How much does it cost?
The cost of spraying foam insulation is higher than insulating with some other insulation products, however spray foam insulation saves on energy costs and lowers utility bills. Monthly savings of 30% or greater can be achieved when compared to alternate insulating systems. The cost of spray foam insulation can often be recovered in less than 5 years, simply on energy savings alone.
How long will foam last?
Once foam is applied to your project, it will last an extremely long time. When properly installed and not altered after installation, the foam will easily last the life of your building. Spray foam has excellent insulating and sealing properties and will out-perform all other types of insulation. Polyurethane foam insulation adheres to nearly all substrates.
