One of the most common questions homeowners ask is, “How long does insulation last?” The answer depends on several factors, including the material type, environmental conditions, and overall maintenance. 

If you live in Selkirk, where temperature swings can be extreme, knowing when insulation needs replacing can make a world of difference in keeping your home efficient and comfortable.

Spray Foam Insulation: Built to Last

If you have spray foam insulation, you’re in luck—it’s one of the most durable options available. High-quality spray foam can last 80 to 100 years, providing a near-permanent solution for home insulation. 

It doesn’t settle or degrade like other materials, and its resistance to moisture and pests makes it a top choice for Manitoba’s climate. Unless damaged during renovations, spray foam rarely needs replacing.

Batt Insulation: Shorter Lifespan, More Maintenance

Fiberglass or batt insulation is another common choice, known for its affordability and accessibility. 

While it can last 70 to 90 years in ideal conditions, it often starts to degrade after 10–15 years, especially in humid or pest-prone areas. 

Signs that batt insulation needs replacement include:

• Visible sagging or settling
• Moisture damage or mold growth
• Increased energy bills due to declining efficiency

When to Upgrade Your Insulation

Even if your insulation isn’t visibly damaged, upgrading to a modern, high-efficiency option can improve energy savings and home comfort. If your insulation is more than a decade old or your home feels drafty in winter and overly hot in summer, it’s time for an inspection.
