Blown-in Insulation

Blown-in insulation, commonly made from fibreglass or cellulose, is a favourite for its ease of installation and effective thermal resistance. Typically, this type of insulation can last up to 20–30 years.

Fibreglass Insulation

Fibreglass insulation, known for its longevity and fire resistance, can last over 30 years.

Cellulose Insulation

Cellulose insulation, often made from recycled materials, offers excellent thermal properties and can last for about 15–30 years.

Spray Foam Insulation

Spray foam insulation is highly efficient and durable, potentially lasting the lifetime of your home when properly installed. Its ability to create an air seal makes it an increasingly popular choice among homeowners.

Factors Affecting Insulation Longevity

Several factors impact the lifespan of your attic insulation. These include environmental conditions like humidity and temperature fluctuations, pest infestations, and improper installation. Regular inspections can help identify issues early and prolong the insulation’s effectiveness.

Recognizing Signs of Insulation Degradation

Keep an eye out for uneven temperatures in your home, increased energy bills, and visible damage to the insulation. These signs indicate it might be time to evaluate your attic insulation.
