Spray Foam Insulation in Thornhill

There is general consensus in the insulation industry that spray foam is the best insulating product when compared to similar products on the market.  If you’re shopping for insulation, and if you’re considering spray foam insulation in Thornhill, it may be time to consider Great Northern Insulation.  We are reputable and respected, and well established in the region.  Our approach to installation is simple - we seal tight and ventilate right.  This combined approach of sealing and ventilating makes for an installation that’s comprehensive and thorough.

For insulation professionals in the industry, spray foam has become their product of choice.  It is generically known as polyurethane foam, and is simply regarded as a better product when comparisons are made.  Spray foam insulation does a much better job of sealing; it provides a better R-value rating than other products; and it adds structural strength where applied.  For the professionals at Great Northern Insulation, there’s no better insulation product, which is why we routinely recommend spray foam for an insulation project.

Many insulation professionals look at spray foam as the ultimate insulating product.  It’s ideal for expansive spaces like the attic, the roof, or right inside the walls.  And best of all, a proper application provides total coverage.  During an installation, the foam insulation is sprayed from a nozzle attachment, and spreads out evenly in its thick liquid form.  It expands into place, and quickly hardens into a super-dense layer.  When the installation is finished, the entire area is coated, including every little crack and crevice.  No other product has this kind of coverage.

An expert application will result in a layer of insulation that is completely impervious to both air and moisture.  In fact, spray foam insulation eliminates the need for a vapor barrier, which saves time and money.  But the application provides much more in terms of benefits:  energy efficiency is optimized; indoor air circulation is enhanced, which also improves air quality; and HVAC equipment operate to it full potential.  With the home now “breathing” properly, and with everything working in balance, seasonal utility bills are also reduced.

At Great Northern Insulation, we often hear from homeowners and contractors, who ask if the spray foam product is right for them.  And most every time, our answer is YES.  We just think that spray foam insulation is the best, especially when installed as part of an entire insulating “system”.  Over and over again, the results seem to confirm the efficacy of the product.  With a proper installation, several issues can be resolved – higher than usual heating/cooling costs; imbalanced heating/cooling cycles; and under-performing HVAC equipment.

Spray foam insulation requires expert installation.  In Thornhill, Great Northern Insulation has installers who are skilled and experienced.  Our people have years of project expertise and install with precision.  They obey building and construction codes; they follow recognized by-laws; and they install based on the manufacturer’s specifications.  At GNI, we stand behind everything we sell and install, and provide our customers with the manufacturer’s warranty.  We want to do it right the first time, whatever the size or scope of the project.

Spray foam insulation requires proficiency and expertise.  Our installers get an understanding of the project, and of the unique challenges that are posed.  We always recommend the product that best suits a customer’s needs.  And most of the time, we will encourage a customer NOT to make spray foam insulation a weekend, do-it-yourself project.  This is a job that is best left to the experts, in other words, to the professionals who understand the product, and the unique aspects of the installation process.

Spray foam insulation was developed in the 60s.  It was used in industrial applications, and was an excellent insulator for use in freezers, coolers, and cold rooms.  The product was improved over the years, and has become the superb insulation product we use today.  The professional installers agree that spray foam insulation is the best for sealer and insulator for large spaces like the attic and the roof.  At Great Northern Insulation, we recommend the product for use in new construction, retrofits, and renovations (residential and commercial).  

When it comes to installation, the importance of a proper install cannot be overstressed.  There is no product that will perform to potential if not properly applied.  At GNI, our installers are licensed and certified experts:  they know how to properly prepare the workspace; they follow the manufacturer’s guidelines; they use the proper safety gear and wear the protective attire; and they make sure to take precautions that will safeguard occupants.  It’s just another example of doing the job right the first time.

Recent industry statistics show exponential growth in the popularity of spray foam (it’s about 40% a year in the last decade).  The popularity has grown primarily because the product has proven itself in all applications.  And while it’s true that spray foam could be more costly than other insulation products, a simple “cost-benefit” assessment shows that the expense is worth it.  This is a premium product, and it delivers premium benefits:  it lasts a lifetime, without the need to replace; it doesn’t need to be replenished; and the “pay-back” is between 2 and 7 years.
