How to Choose Insulation for Exterior vs Interior Walls
Although insulation is often underestimated, it actually plays a massive role in comfort, energy efficiency, and cost savings. Without being said, both interior and exterior walls should be insulated to reap maximum benefits. Spray foam insulation in Mississauga is widely regarded as one of the most effective insulations on the market; however, different varieties may be necessary for interior walls vs. exterior walls. If you have been struggling with drafts, high energy bills, and inconsistent temperatures in your property, then you may find spray foam insulation costs to be a worthwhile investment.

Understanding the Role of Wall Insulation

The purpose of wall insulation is to limit heat transfer. Spray foam insulation is applied to the inside of your walls in order to prevent heat from leaving your home in the winter and heat from entering your home in the summer. This helps contribute to stable temperatures, greater comfort and lower energy costs. Since spray foam insulation is water-resistant, it also has the potential to limit moisture and humidity infiltration.
Insulation for Exterior Walls
Exterior walls need protection against outdoor temperatures. Given the extreme temperature changes that occur in the GTA, it is vital that your insulation is waterproof and airtight for optimal performance. Investing in a more durable exterior insulation will also ensure it lasts longer.
When it comes to exterior wall insulation, closed-cell spray foam insulation is always highly recommended. Closed-cell insulation has a higher R-value per square inch than open-cell insulation. The high R-value of 7 effectively prevents air, water and heat from penetrating your home from the outdoors. This allows it to perform extremely well regardless of the weather outside. Closed-cell insulation does not require a vapour barrier and can add structural strength to your home. It is important to note that closed-cell insulation is more expensive than open-cell; however, the energy-saving benefits make the spray foam insulation costs well worth it.
Insulation for Interior Walls
While temperature regulation is still necessary for interior walls, indoor walls do not require as high of an R-value since they are not exposed to extreme temperatures and conditions. In this case, open-cell insulation is sufficient. It has an R-value of about 4, still offering better performance than most other insulation varieties like fibreglass and batt insulation. The waterproof capabilities of closed-cell insulation are not entirely necessary for interior walls since leaks often originate from outside the home.
Open-cell insulation also offers better “soundproofing” capabilities compared to closed-cell, making it great for interior applications where you want to minimize sound transmission between rooms.
Choose the Right Spray Foam Insulation for Your Walls
Ultimately, choosing the right insulation for both interior and exterior walls can make a noticeable difference in how comfortable and energy-efficient your home feels year-round.
