Spray on insulation is created by applying liquid foam that expands to fill voids in a house or building. Polyurethane is typically used, but some manufacturers produce soy-based foam to create an earth-friendly insulation. The millions of tiny air bubbles in the foam create an insulating barrier that helps reduce heating and cooling costs.
Spray On Insulation Concerns
Spray on insulation is expensive when compared to traditional insulation. The cost of spray on insulation generally runs two to three times higher than fiberglass batten/blanket insulation.
The complexity of installing spray on insulation in an existing home usually outweighs the benefits of its use. The removal of existing insulation, creating access behind walls and the application of foam are labor-intensive activities. Cost, time and mess are all increased in existing homes.
Spray on insulation requires professional application. Since this is not a do-it-yourself job, cost and complexity are increased.
Spray on insulation foam is quick drying and very sticky. Any spills that occur during installation will result in difficult and costly clean up.
The Advantages of Spray On Insulation
Spray on insulation has a much higher R-value than traditional fiberglass insulation. Properly installed, spray on insulation has twice the insulating properties of fiberglass. As spray on foam is applied, it expands to create an airtight seal, adding to the energy saving nature of this insulation.
Spray on insulation increases the structural integrity of a home. By design, spray on foam insulation is highly adhesive. The result is that the structural elements of a home are glued together in addition to whatever fastening was applied during construction. This "belt and suspenders" approach makes a house stronger in the face of the high winds delivered by a hurricane or other strong storm.
Applied as a liquid, spray on insulation is perfect for insulating small or hard to reach areas. With traditional insulation, tight areas result in improperly installed or minimal insulation that leads to gaps in your home's insulation envelope.
Insulation is an important component of energy efficient homes. Using green insulation will help save energy, money and the environment.
Denim insulation is quickly becoming a "green" alternative to traditional fiberglass insulation.
