Loft insulation is an essential component to any energy-efficient home. It adds a layer of protection to your home and helps to keep your space warm in the winter while keeping it cool during the summer. However, many homeowners ask us ‘how long does loft insulation last’ or when they should replace it.
‘How long does loft insulation last’ depends on the type of material that is installed. Here’s a breakdown of the most common types of insulation and their longevity:
Fiberglass insulation is a common type of insulation material. It is made from very thin fibers of glass woven into a blanket-like material. It is estimated that fiberglass can last up to 100 years when installed correctly. However, a typical lifespan for this type of insulation is around 20 to 30 years.
Cellulose is another common type of insulation material. It is made from recycled paper and is known for its sound-proofing qualities. Cellulose insulation can last up to 30 years, but some experts say that it may last even longer with proper installation.
Mineral Wool Insulation:
Mineral wool insulation is another popular material to insulate your loft. It is made from rock, slag, or glass and is known for its ability to absorb sound. The average lifespan of mineral wool insulation is around 100 years.
Spray Foam Insulation:
Spray foam insulation is a new type of insulation that is quickly becoming popular among homeowners. It is made by mixing two chemicals that react and expand rapidly once they are sprayed onto the surface. Spray foam insulation can last up to 80 years when correctly installed.
It’s essential to understand ‘how long does loft insulation last’ as the lifespan of your insulation can be shortened if it is not correctly installed or damaged. Proper installation is key to ensuring that your insulation will last as long as possible. It’s advised to use professional installers for the best results.
It is also recommended to have your insulation inspected every few years to ensure that it is still performing correctly. Any damages or wear and tear can be identified and repaired before it causes significant problems.
