Why Spray Polyurethane Foam is One Of The 21st Century’s Best Construction and Development Materials
The galvanisation and reinforcement of steel and the discovery of aluminum were some of the biggest milestones the early centuries achieved when it came to building properties. In addition, the creation of synthetic yet reinforced concrete that can last for centuries played a huge role in lengthening the lifespan and performance of modern-day buildings. However, one of the 20th and 21st centuries’ best innovations was the improvement and expanded use of spray polyurethane foam or SPF.
Ener-Spray takes pride in being one of the best providers of SPF roofing, interior, and exterior application services. However, without SPF, we won’t be much of a thriving business. SPF is an adaptable material capable of retrofitting roofs, filling gaps in older roofs, and providing exceptional insulation to houses and commercial and industrial properties.
Polyurethane is a resin based foam material that can expand and harden about 60 times bigger than its liquid form. A chemical interaction creates this reaction. The thick material is what delivers exceptional exterior protection for many homes and commercial and industrial properties.
For a more technical explanation, Building Energy has a great explanation about it below. Read more about how SPF actually works.
Spray foam insulation is developed from 2 types of composite material, polyurethane and isocyanate. When combined, the 2 materials chemically react to expand and harden. During the insulation process, the 2 materials are sprayed at the same time from the tip of a spray foam gun allowing them to expand and form a protective layer of spray foam insulation over a designated area. Spray foam is widely promoted as a green building material for its ability to improve energy efficiency. It insulates better than fiberglass or cellulose leading to major heating and cooling cost savings for a homeowner.
While all spray foams contain petroleum-based chemicals, some manufacturers have ‘greened’ their formula by reducing the percentage of petroleum-based chemicals in their polyol resin component and replaced that with resin derived from soy oil or castor oil. These are known as soy-based foams. (Continued)
One of the primary uses of SPF is internal property insulation. While it seems like an unnecessary residential reinforcement, it’s one of the most sought-for uses of SPF. Property insulation lowers the possibility of external temperatures from entering the property. In turn, thermostat levels are more accurate allowing homeowners to save more money in utilities.
In addition, insulation slows down molecules of sound, temperature, and other wind-transmitted matter. Therefore, you can expect quieter nights and sleepful evenings for your home too.

How Insulation Works
To understand how insulation works it helps to understand heat flow, which involves three basic mechanisms — conduction, convection, and radiation. Conduction is the way heat moves through materials, such as when a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Convection is the way heat circulates through liquids and gases, and is why lighter, warmer air rises, and cooler, denser air sinks in your home. Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy.
Most common insulation materials work by slowing conductive heat flow and–to a lesser extent–convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must face an air space.
Regardless of the mechanism, heat flows from warmer to cooler until there is no longer a temperature difference. In your home, this means that in winter, heat flows directly from all heated living spaces to adjacent unheated attics, garages, basements, and even to the outdoors. Heat flow can also move indirectly through interior ceilings, walls, and floors–wherever there is a difference in temperature. During the cooling season, heat flows from the outdoors to the interior of a house. (Continued)
