As compared to alternative roofing and insulation schemes, monthly energy and utility benefits of 40% or more can be reached. Simply by saving electricity, the expense of a spray foam roof or insulation device will also be recovered in less than 5 years.

Materials for Insulation Comparison
There are many distinctions to be made between spray foam and other traditional insulating materials. It does not sag or sink into the wall cavity over time, for example. It conforms to the structure of the cavity it is sprayed into and creates a permanent air barrier. Standard insulation often has a high risk of sagging over time because it does not stick precisely to the ground. If conventional insulation isn’t built correctly around framing, plumbing, and electrical, voids as small as 1-2 percent will reduce the effective R-value by 25-40%. Will they apples to apples? Traditional insulation materials can only attain their claimed R-value under ideal laboratory conditions with no air movement.
If you live in the real world, as you do, this is obviously not true. Spray foam’s high aged R-value remains stable regardless of the climate or circumstances.
Advantages of a Builder
Most R-value, air barrier, and water vapour permeance specifications can be met by installing closed cell spray foam between studs. Due to the large R-value of 6.3 per inch, this method often decreases the requirements of an HVAC system, enabling smaller devices to be used and allowing stud and rafter sizes to be reduced. Wall racking resistance can be up to three times greater than traditional insulation in framed buildings, and mould growth is highly rare due to the limitation of air flow and moisture accumulation.
The New Paradigm
Spray foam insulation solutions are quickly becoming the industry norm in new construction. Today’s construction workers and homeowners are aware of the advantages of spray foam insulation over conventional insulation.
The gimmicks and rituals of the past could not trick them. Rising energy prices and green building campaigns have pushed the best of the best building materials to the forefront, and the results for spray foam speak for themselves. Spray foam is now the industry norm for high-quality builders and construction professionals around the world.
