With rising energy costs and growing demand to make buildings more energy-efficient, many contractors are thinking about adding foam insulation to their product offering.
Whether it is whole home insulation, retro-fitting an existing attic or spraying foam in a basement, all solutions have a dramatic effect on monthly energy consumption. Typical applications may see a result of 50% reduction in heating and cooling costs.
Whether it is whole home insulation, retro-fitting an existing attic or spraying foam in a basement, all solutions have a dramatic effect on your monthly energy consumption.
Typical applications may see a result of 50% reduction in heating and cooling costs. Important to note, is not only will a great reduction in energy consumption be produced, a vast reduction in your carbon emissions will also be seen in correspondence with the reduction of energy usage.
Spray foam is a high quality product that is the best insulating material on the market today. It is sprayed in place and expands immediately after being applied, to fill in all voids, gaps, and cracks.
Spray foam insulation meets the latest demand trends for energy-efficiency and green construction. Unsurpassed air barrier and high R-value gives spray foam a distinct advantage over other insulating products, providing homeowner’s financial savings of 40% or more off of their heating and cooling bills.
Installing closed cell spray foam in between studs will meet most R-value, air barrier and water vapor permanence requirements. A spray foam system also reduces the requirements of an HVAC system, allowing smaller systems to be used and also permits stud and rafter size reduction due to a high R-value.
Wall racking strength also increases to up to three times stronger than with conventional insulation in framed walls and with the restriction in air movement and moisture accumulation, the possibility of mold growth is extremely unlikely.
Spray Foam used for residential or commercial insulation is categorized into two types, "open-cell" or "closed-cell”. Open cell is lightweight foam that is flexible, and an excellent air barrier. With open cell foam the tiny cells of the foam are not completely closed and air fills all of the “open” space inside the material.
Closed cell foam is higher density foam, and a moisture barrier when applied at a thickness of 50mm or more. Closed-cell foam incorporates an insulating gas that is retained within the cells ("blowing agent"), which leads to the highly efficient insulating properties of the material.
Open Cell Spray Foam Insulation is a high yield, high quality product that is essential for today's rising energy costs. One of the advantages that the lower density provides is a more economical yield, since foam density is directly related to yield (lower density = higher yield).
Although the R-value of open-cell foam is about half that of closed-cell foams, these products can still provide excellent thermal insulating and air barrier properties.
Closed cell polyurethane spray foam is among the most efficient insulating materials commercially available, with R-values double that of other insulation materials. Closed-cell polyurethane foams are usually characterized by their rigidity and strength, in addition to the high R-Value.
The closed-cell nature of this foam provides for a highly effective air barrier, low moisture vapor permeability (often referred to as the "Perm" rating), and excellent resistance to water.
When it comes to insulation no competing product can compare to the features of spray foam. Traditional insulation like fiberglass was developed more than half a century ago to provide a single benefit: R-value, which is the same as stopping heat flow by means of conduction. In those days, little thought was devoted to environmental or health impact.
Obviously, home owners’ expectations and building science has developed tremendously over the last 50 years, culminating in the perfection of foam insulation as the only sensible option for today’s challenges.
Are you looking for a sustainable roofing system for commercial and industrial applications that doesn’t leak, reduces life cycle costs, and contributes to overall building energy savings?
With construction expenses increasing and greater awareness of the long-term affects of energy use, building owners and design professionals are looking for cost-effective alternatives to conventional roofs.
As green building initiatives develop and the cost of energy increases, spray foam insulation, spray foam roofing and protective coatings will continue to offer design professionals and builders high-performance alternatives to traditional roofing and insulation materials.

SPF is a spray-applied insulating foam plastic that is formed by spraying two components – isocyanate and a resin – to form a rigid, fully adhered, insulating material.
