When was the last time you thought about the insulation in your home? For many homeowners, insulation is often overlooked, yet it’s a critical component that plays an important role in energy efficiency, comfort and the safety of your living space. How long does insulation last, and when should it be replaced?
The lifespan of insulation can vary depending on the type used, your home’s environmental conditions and how well it was installed. In this blog post, we’ll discuss the different types of insulation and their expected lifespans.
Types of Insulation and Their Lifespans
Spray Foam Insulation
Lifespan: 80+ years
Where it’s used: Spray foam insulation is one of the most durable and long-lasting insulation options available. It can last for decades without needing to be replaced, and its adhesive properties help it form an airtight barrier that’s excellent for controlling moisture and sealing air leaks. It’s ideal for hard-to-reach areas like crawl spaces, attics and walls in climates that experience a wide range of temperatures. Spray foam works well in regions with high humidity or frequent weather changes, as it helps prevent moisture buildup.
Fiberglass Insulation
Lifespan: 20 to 30 years
Where it’s used: Fiberglass insulation is a popular and cost-effective option used in walls, attics and floors. It’s made from fine glass fibers and is effective at trapping air to regulate temperature. This type of insulation is often used in areas where you need thermal and sound insulation, making it a good choice for homes in moderate climates. However, fiberglass can degrade faster if exposed to moisture or pests.
Cellulose Insulation
Lifespan: 20 to 30 years
Where it’s used: Cellulose is made from recycled paper and treated for fire resistance. While it offers strong thermal resistance, it tends to absorb moisture, which can reduce its effectiveness over time. It’s typically blown into attics and walls, but because it’s prone to moisture absorption, it’s more suitable for dry climates. If you live in an area with high rainfall or humidity, it may require more frequent replacements.
Batt Insulation
Lifespan: 20 to 30 years
Where it’s used: Batt insulation is made from fiberglass or mineral wool and comes in pre-cut panels, making it easy to install in wall cavities, floors and ceilings. It’s widely used in new home construction and renovations. Batt insulation is suitable for homes in mild to moderate climates, though it should be inspected regularly for wear and tear.
Blown-In Insulation
Lifespan: 20 to 30 years
Where it’s used: Blown-in insulation is applied using specialized equipment and is commonly made of cellulose or fiberglass. It provides excellent coverage for irregularly shaped spaces like attics. This type of insulation is great for colder climates where extra coverage is necessary to maintain a stable indoor temperature.
Radiant Barrier Insulation
Lifespan: 10 to 20 years
Where it’s used: Radiant barriers work by reflecting heat away from the home. They’re often installed in attics to reduce heat transfer during hot months. This is especially beneficial in hot climates where keeping cool air inside is a priority. However, they have a shorter lifespan compared to other types.
Signs It’s Time to Replace Your Insulation
Even though insulation is designed to last a long time, it won’t last forever. Here are some signs that it might be time to consider replacing your insulation:
- Higher energy bills
- Uneven temperatures between rooms
- Drafts near doors or windows
- Water damage or mold growth
- Visible damage
- Pest infestations
Health Risks of Poor Insulation
Poor or degraded insulation can affect your health. When insulation is compromised, your home may experience moisture issues or mold growth, which can trigger allergies, asthma, or other respiratory problems. Mold growth, in particular, can be hazardous and may lead to serious health conditions if not addressed.
