FAQ’s

Q. What is R-value?

A. The capacity of an insulating material to resist heat flow. The higher the R-value, the greater the insulating power.

Q. What is the insulation R-value of your systems?

A. Our polyurethane foam systems are closed-cell, with a superior effective R-value of over 6.9 per inch.

 

Q. Is Closed Cell Spray Foam suitable for residential retrofit insulation applications?

A. Closed Cell Spray Foam (CCSF) is an ideal product for insulating and air-sealing existing homes. CCSF can be used to create energy-saving unvented attics and crawlspaces that seal against air leakage and bring under-insulated and leaky HVAC ducts inside the conditioned space of the building. In addition CCSF, can be used to insulate and air-seal band and rim joist areas where the framing meets the home’s foundation.

Q. What are the Advantages of Spray Foam?

A. Since spray foam is an approved air barrier, outside air cannot seep through walls causing drafts, cold spots, dampness, and other discomfort. It also means that moisture laden air cannot enter the walls and condense on cold surfaces causing mold, mildew and premature decay. Spray foam insulation is also recognized for its incredible ability to absorb sound. Moreover, it is not uncommon for homes with foam to experience more than a 50% reduction in heating/cooling consumption compared to a similar house with fiberglass. This is because of spray foam’s unique ability to create a custom air seal and retain its R-value in extreme weather conditions.

Q. Will Spray Foam Break Down, Sag or Settle Over Time?

A. No, spray foam will not break down or settle over time like other insulation such as fiberglass and cellulose. However, if the foam is left exposed to UV light then it will disintegrate over time.

Q. Am I Allowed to Apply Spray Foam to the Underside of the Roof Without Ventilation?

A. Yes. Section R806.4 of the 2006 International Residential Code specifically permits unvented attics with certain provisions; namely, that an air-impermeable insulation is applied to the underside of the roof with an appropriate r-value necessary to maintain the monthly average temperature of the surface of the foam above 45°F in order to prevent a condensing surface. The condensing surface is on the face of the foam and not the roof sheathing because the foam bonds to the sheathing creating a single cohesive, air-impermeable assembly. (Please note, fiberglass and cellulose do not qualify as air-impermeable. This also means there are certain limitations when combining fiberglass over the foam in an unvented roof). The code defines an air-impermeable insulation as having an air-permeance less than 0.02L/s-m2 (both open and closed-cell foam qualify).

Q. Can an insulation system add structural strength?

A. Spray-applied closed-cell polyurethane foam is the only insulation material that adds structural integrity throughout the wall system. Testing conducted by the National Association of Home Builders (NAHB) Research Center and the Canadian Construction Materials Centre shows spray-applied polyurethane foam insulation between wood- and steel-stud wall panels increased rack and shear strength two to three times compared with standard stick-built components with glass fiber insulation.

Q. How Much Will I Save? What is the Payback Period?

A. Past case studies and experience shows that a properly insulated home with spray foam will reduce heating/cooling consumption by around 50% or more depending on several factors. Window fenestration, orientation, and HVAC sizing are just a few of the variables that will determine whole house performance. Through the use of energy modeling software, such as REM/Rate, you can closely predict the energy usage of a home with either spray foam or fiberglass. These programs can be used to estimate the return-oninvestment or payback period by upgrading to spray foam insulation.Our experience and research shows that the payback period from the cost to upgrade to spray foam ranges between 2-5 years depending on fuel cost and whether rebates or tax incentives are available. The annual energy savings can become quite significant as the cost for energy continues to rise each year.
