Lifespan of Spray Foam Insulation

spray foam insulation torontoSpray foam insulation is the longest-lasting option available these days. There are two primary varieties of spray foam insulation you can choose between: open-cell and closed-cell. Both of these can last well over 50 years, with closed-cell spray foam insulation lasting anywhere from 80 to 100 years. For most homeowners, spray foam insulation will last a lifetime without the need for touchups, making it a worthwhile investment. Other insulation options such as:

  • Fibreglass Insulation: Can last anywhere from 15 to 30 years.
  • Cellulose Insulation: Will last from 20-30 years
  • Batt Insulation: Only lasts up to 15 years if maintained properly.

Factors That Contribute to Spray Foam Insulation Longevity

There are a few factors that contribute to the high life expectancy of spray foam insulation. 

Application Method

The way spray foam insulation is applied allows it to last decades without needing to be replaced. As the name suggests, this insulation is spray-applied to the surfaces of your home as a liquid before drying down into a foam material. This application method allows the insulation to make excellent contact with every nook and corner of your home, preventing it from becoming damaged easily. 

Water Resistance

Spray foam insulation is naturally resistant to moisture, and closed-cell varieties are entirely waterproof, allowing them to withstand plumbing leaks and/or extreme weather conditions. Other common insulation types, such as fibreglass and batt insulation, need to be replaced if they ever make any type of contact with water. Since spray foam doesn’t succumb to water, it rarely needs to be replaced.

How to Extend the Lifespan of Your Spray Foam Insulation

  • Utilize a reputable insulation contractor for installation
  • Protect any exposed areas from harsh UV rays with protective coatings on windows
  • If you opted for open-cell spray foam insulation, add a vapour barrier
  • Conduct regular inspections to ensure there is no physical damage or shrinkage
