Here at GNI we are always looking for the next best insulation breakthrough. Whether that involves a new type of insulation or a state-of-the-art installation method, we are continually trialing new products and techniques to provide our customers with cutting edge insulation installs that are right for their home. Balancing cost-effectiveness and comfort is always our target, which means that you will always get the best insulation possible for your home and for your budget.

We’re Always Looking for the Best Insulation

When it comes down to keeping a home comfortably and affordably insulated, it is important for us to always be on top of cutting-edge insulation materials. This means that we always have our eyes out for the next best thing; ensuring that our customers have access to the finest spray foam, fibreglass batts, and blown-in cellulose products. In other words, when you work with GNI, you can be sure that your upgrades will not only use the best insulation products on the market, but also that you are upgrading in the most cost-effective manner possible. This helps you to save energy, money and improve your home all at once. 

Save Energy and Upgrade with Ease

When you take advantage of our cutting edge insulation products, you are able to save energy and make upgrades without causing a headache for yourself. Our expert installers are able to assist you with any questions you may have about your improvements or renovations, and are happy to perform a free in-home assessment to help you get started. So, if you are wondering what the best insulation choice would be for your needs, GNI has your answer. We can help you target the areas of your home that need the most attention first, and provide you with a plan of attack for making the most cost-effective upgrades possible. Our goal is to help you save energy, money, and improve your home comfort. 

Spray Foam, Fibreglass Batts, or Blown-in Cellulose?

Quite often we are asked what the insulating material on the market is, and our answer is always the same: it depends on a number of different factors. Factors such as: the size of the home, the area of the home that needs improvement, the budget, and if there are any other upgrades or renovations planned for the near future. While spray foam, fibreglass batts and blown-in cellulose each offer distinct advantages, the best insulation choice may be difficult to determine without professional help. 

GNI is able to schedule an energy assessment for your home, which provides you with an in depth look at your current energy performance, along with suggestions for the most cost-effective upgrades you could make. This will not only make it even easier for you to choose the best insulation for your needs, but it also makes it easier to make upgrades that will help you save energy and improve home comfort. Additionally, a home energy assessment is an important part of the application process for the Home Efficiency Rebate program in Ontario.

Why Use Cutting Edge Insulation & Installation Techniques?

When you hear that GNI uses cutting edge insulation material and installation techniques, you may draw the conclusion that it must be expensive. In fact, the opposite is closer to the truth – lesser quality products installed unprofessionally can lead to problems that can actually cause you to pay more out of pocket. The better the performance of your home’s insulation, in terms of quality of both material and installation, the bigger the energy savings and home comfort improvements. As the R-Value of different products continue to improve per inch of application, and as new installation techniques are discovered and mastered, the most cutting edge insulation products will continue to provide cost-effective improvements for homeowners. 

For example, by making upgrades with the market’s most cutting edge insulation products and installation, you can see improvements such as:

  • Higher levels of home comfort
  • Fewer drafts
  • Lower utility costs
  • Better interior air quality
  • More consistent temperatures on different floors and in different rooms
  • A higher market value when it comes time to sell

Take Advantage of the Rebates Available Now in Ontario

As mentioned earlier, a home energy assessment is an important part of securing rebates through the Home Efficiency Rebate program. With up to $5,000 of home reno rebates available, GNI can help you determine which rebates would be the best for you to aim towards. The goal of the program is to help Ontario homeowners save energy and improve their homes, and with the help of GNI, you can accomplish that for the lowest upfront cost possible. 

For example, we may recommend that you use spray foam in your rim joists to help you reach the requirements of the $2000 rebate for upgrading wall insulation; or use blown-in cellulose to help you insulate your wall cavities without having to tear down your drywall. Overall, there is no single type of insulating material that is the best for every purpose. Instead, it is best to have a professional assess your home and help you choose which of the market’s most cutting edge insulation products are the right fit for your needs and budget.
