Should I Get Spray Foam Insulation?

February 10, 2018

If you’re thinking about installing spray foam insulation, and wondering if it’s right for the job, then understanding the product will help with decision making. Like anything, there are pros and cons, cost considerations, and long-term value. And like any purchase, being well informed as a consumer is an advantage when making decisions – particularly when an investment is involved.

The benefits of spray foam insulation

Industry professionals recognize spray foam insulation as the most versatile product on the market. When professionally installed, spray foam insulation provides better energy-efficiency, better airtightness, and better R-Value than any comparable product available today.

In many homes, spray foam insulation has proven to be effective in resolving a number of home energy issues – everything from high seasonal energy costs, to unbalanced heating and cooling patterns, to poor overall HVAC performance. The aim, naturally, is to resolve these issues.

The primary benefit of installing spray foam insulation is its superior capacity to seal a space. Attic or basement, spray foam seals completely, and forms a combination air and vapour barrier. Beyond insulating the space, the “envelope” prevents condensation and undesirable heat loss.

When it comes to insulating a home, spray foam provides higher R-Values than other products. As well, the installation is competitive with other installations like rigid foam, or a combination of more than one product. A good installation makes a home significantly more energy efficient.

  • superior energy-efficiency throughout
  • more effective sealing and airtightness
  • higher thermal R-Values when compared
  • added structural strength when installed
  • much reduced potential for mildew/mold

What are the related safety considerations?

As a chemical compound, spray foam requires special handling from preparation to installation. Anything less poses the potential for health and safety risks.

When installed according to the manufacturer’s guidelines and installation standards, spray foam is a safe and effective product offering. At the same time, a second-rate installation, without professional oversight can be problematic. Worse still, unraveling a bad spray foam install can be stressful and costly.

Spray foam requires the expertise of trained technicians – installers who understand the nuances of the product and the unique nature of the application process. Beyond that, highly experienced installers do everything to code, properly prepare the install space, and ensure complete safety.

One of the best returns-on-investment

Because it’s a multi-purpose installation, spray foam does everything in a single application. More than just insulation, the finished space is highly energy efficient. The superior performance is key to dramatically decreasing heating and cooling costs. The annual utility savings are substantial.

Long term, the energy savings with spray foam allow for a very reasonable "pay back" period on the initial investment. And while product and application are more costly than other options, the return-on-investment makes economic sense for most (including higher resale value on a home).

Choosing a good spray foam contractor

Like any professional contractor, it’s important for a homeowner to choose a spray foam expert that’s reliable, reputable, and highly experienced. For best results, a professional is preferred.

  • appropriate training with spray foam products
  • good industry reputation and client references
  • providing good advice on product/installation
  • step-by-step oversight throughout the process
  • assurance of proper health/safety precautions

Established contractors usually offer financing options to better manage the upfront investment. As well, there is always welcome advice on available government incentives and/or rebates.
