Attic Insulation

Attic insulation plays a critical role in keeping your home cooled and heated appropriately. Conduction and convection are two important terms you need to know to understand how insulation works. Conduction is how heat moves through materials, while convection is how heat circulates through the air.

Insulation works by reducing the conductive flow of the heat and minimizing convection. The insulation in your attic, exterior walls, garage, basement, and other areas of your home keep the desired air from escaping and unwanted air out. At the core, attic insulation helps you save money on your energy bills.

How Long Does Attic Insulation Last?

Your attic insulation’s lifespan varies on many different factors, but most last up to 80 years. Other types of insulation can last up to 100 years. Of course, this is all dependent on the effects time has on your insulation. For example, water can increase the rate of degradation in insulation. The presence of moisture allows mold spores to thrive. Mold and mildew not only reduce the effectiveness of insulation but reduces indoor air quality.

 

Types of Attic Insulation

The type of insulation you have in your home will be dependent on the lifespan. All types of insulation have their advantages and disadvantages. Fiberglass, spray foam insulation, and cellulose insulation are the most common options.

Fiberglass Insulation: As the most common type of attic insulation, fiberglass is inexpensive and is easily installed for attics. Installed correctly, fiberglass insulation will last homeowners for years to come. It is best suited for humid environments.

Spray Foam Insulation: Better at sealing in air and preventing water exposure, spray foam insulation is more expensive than fiberglass. Since it helps prevent water exposure to your home, it fights against mold growth too.

Cellulose Insulation: Manufactured from recycled paper, cellulose insulation is the greenest option for insulation options. It is best used for floorboards or closed spaces like walls or attics. More importantly, cellulose insulation is fire retardant.
