Pick the Right Kind of Insulation for Your Garage

This is especially important, given that your garage is subject to the elements and outdoor weather changes. If you live in Toronto, the GTA, or any city with diverse weather conditions, you’ll want to select an insulation that is water-resistant, has a high R-value, and provides an airtight seal. Based on these criteria, there is no doubt that spray foam insulation is the best choice for garage applications.

Benefits of Spray Foam Insulation in Toronto

Has a high R-value between 3.5 and 7. This means that it effectively keeps heat out in the summer and heat in during winter.
Offers an airtight seal that prevents drafts of any kind. This is because the insulation is spray-applied, allowing it to make contact with every surface in your garage.
It is water-resistant, and even completely waterproof if you install a closed-cell variety. This can help prevent mold and deter rain from entering your garage.

Key Areas to Insulate in Your Garage

Once you have selected your insulation variety, you need to ensure that you insulate key areas in your garage to achieve the best results. The garage door is usually an overlooked surface when it comes to garage insulation. However, the garage door is usually the largest source of heat loss, since most are made of thin metal. Insulating it will help keep the temperature inside more stable. You’ll also want to ensure that exterior-facing walls are prioritized when insulating. This will prevent heat loss and promote stable temperatures.

Benefits of Garage Insulation

Improved Energy Efficiency: Insulating your garage reduces heat loss in winter and keeps it cooler in summer, lowering your overall energy bills.
Enhanced Comfort: A well-insulated garage maintains a more stable temperature, making it more usable as a workshop, gym, or storage space.
Protection for Stored Items: Insulation helps prevent moisture buildup and extreme temperature fluctuations, protecting tools, equipment, and belongings from damage.
