How Long Does Insulation Last? A Lifespan Guide

When it comes to home insulation, one of the most common questions homeowners ask is, “How long does insulation last?” The answer varies depending on the type of insulation used, how well it was installed, and the environmental conditions it’s exposed to. At Brisbane Insulation, we believe it’s crucial to understand the lifespan of different insulation materials to ensure your home remains energy-efficient, comfortable, and cost-effective.


Here’s a comprehensive guide to help you understand the lifespan of insulation and when it might be time to upgrade.

 

Even the best insulation won’t last forever. Look out for these tell-tale signs that your insulation might be due for an upgrade:

Fluctuating indoor temperatures despite consistent HVAC use.

Increased energy bills, indicating reduced thermal efficiency.

Visible damage or deterioration such as mould, moisture, or pest infestation.

Unusual drafts or cold spots in your home.

Ageing insulation that’s nearing or past its expected lifespan.


If your insulation is more than 20 years old, especially fibreglass or cellulose, it’s a good idea to have it professionally replaced to ensure your home is properly insulated.


 

The Lifespan of Different Types of Insulation


Other Insulation – 15 to 20 Years


Cellulose insulation, made from recycled paper treated with fire retardants and fibreglass insulation are cost-effective and eco-conscious choices. However, the older products have a shorter lifespan of 15 to 20 years. This material can settle significantly over time, leading to reduced performance.


Moisture and pests can further compromise its durability, making it less suitable for regions with high humidity or risk of termite infestations.



With Brisbane Insulation Earthwool batts are an exceptional choice for modern insulation needs. Known for their sustainability and high thermal performance, Earthwool batts come with a 50-year warranty, giving homeowners peace of mind for decades. Made from recycled glass bottles and natural sand, Earthwool batts are durable, eco-friendly, and resistant to degradation under normal conditions.


While the warranty covers 50 years, their performance will extend beyond that with proper installation and maintenance. If you’re considering insulation that stands the test of time, Earthwool batts are a stellar option.

 

Why Upgrading Insulation is a Smart Investment


Replacing old insulation not only enhances comfort but also significantly reduces energy costs. Modern materials like Earthwool batts offer superior performance, longer lifespans, and are more environmentally friendly than older insulation types.


Additionally, Brisbane’s climate can be demanding on insulation. Investing in high-quality, long-lasting materials ensures your home remains efficient, regardless of weather extremes.


 

Insulation is a critical component of any home, but its effectiveness diminishes over time. While Earthwool batts can last 50 years with their impressive warranty, other types like fibreglass or cellulose may only perform optimally for 20 years. Regular inspections and timely upgrades are essential for maintaining a comfortable and energy-efficient home.


If you’re uncertain about your home’s insulation or suspect it’s time for a replacement, Brisbane Insulation is here to help. Contact us today for expert advice, a free inspection, or a quote to upgrade your insulation with the best materials available.
