How Long Does Blown in Insulation Last: Unveiled Lifespan
Blown-in insulation typically lasts for about 20 to 30 years. Proper installation and conditions can extend its longevity.
Choosing the right insulation for your home is crucial for energy efficiency and comfort. Blown-in insulation, a popular choice among homeowners, offers effective thermal performance and can be installed in various spaces within a home, including attics and walls. It consists of small particles of fiber, foam, or other materials, which are blown into building cavities to prevent heat loss.
The performance of blown-in insulation depends on factors such as material type, moisture exposure, and installation quality. Ensuring it is undisturbed and kept dry helps maintain its effectiveness over time, contributing to a cozy and energy-smart living environment.
Introduction To Blown in Insulation
Blown in insulation is a modern solution for keeping homes warm in winter and cool in summer. It is quick to install and fits easily into odd spaces, small gaps, and hard-to-reach areas. This method provides a seamless thermal blanket that enhances energy efficiency. Homeowners often choose blown-in insulation for both new construction and upgrading existing insulation.
Understanding Blown-in Insulation
Blown-in insulation involves using a machine to blow insulating material into required spaces. Professionals typically perform this task. It is suitable for attics, walls, and crawl spaces. The density of the installation can vary, making it adaptable for different needs and achieving desired R-values, a measure of thermal resistance.
Common Types Of Blown-in Insulation Materials
Fiberglass: Made from recycled glass material and sand.
Cellulose: Consists mostly of recycled newspaper with fire retardant.
Mineral Wool: Made from rock or steel slag, offering both insulation and fire resistance.
Factors Affecting The Lifespan Of Blown-in Insulation
How long will your blown-in insulation last? The answer isn't just a number. It's a mix of things like what the insulation is made of, where you live, and who puts it in. Let's dig into these factors.
Material Quality And Durability
The type of material makes a big difference. There are mainly two kinds:
Fiberglass – It's made of tiny glass fibers. It can last up to 100 years if kept dry.
Cellulose – This comes from recycled paper. It has a shorter life, about 20-30 years.
But, the quality isn't just about type. It's also about how it’s made. Higher quality usually means longer-lasting insulation.
Environmental Influences
The place where you live plays a part too. Think of:
Moisture – Water can break down insulation faster. Keeping things dry is key.
Temperature – Big temperature swings can make insulation “settle”. That means it gets less fluffy over time.
Pests – Bugs and critters can hurt your insulation. Sealing gaps helps keep them out.
Installation Quality
Finally, who puts in your insulation matters a lot. A pro knows how to:
Distribute evenly – No gaps mean better coverage.
Avoid compression – Keeping the air in keeps the warmth in too.
Seal it up – Proper sealing stops moisture and bugs.
