Insulation Materials That Last Long

Spraytech Insulators is essential for maintaining energy efficiency over time. While many options exist, not all offer the same longevity or performance under varying environmental conditions. The most long-lasting insulation materials resist moisture, pests, and degradation while retaining their R-value for decades.

Fiberglass, spray foam, and cellulose remain popular, but each has unique advantages and lifespans depending on installation quality and maintenance.

Comparing Lifespan and Performance

Fiberglass insulation can last 80–100 years when kept dry and undisturbed. It’s non-combustible and resists mold growth, making it ideal for most attics. Spray foam insulation forms an airtight seal and can last 30–50 years while preventing air leaks and water infiltration.

Cellulose insulation, made from recycled paper treated with fire retardants, has a lifespan of 20–30 years and offers eco-friendly benefits. According to Building Insulation Research, the longevity of any material depends on ventilation, humidity control, and proper installation.

Regular inspections help detect settling, moisture, or pest issues early. Investing in long-lasting insulation materials ensures consistent energy performance, lower maintenance costs, and improved home comfort for decades.
