Types of Attic Insulation

A-1 Insulation is a smart home improvement that makes it easier for HVAC systems to maintain an appropriate indoor temperature. It also prevents unwanted heat loss during winter and excessive heat gain in summer, which saves on energy costs. Attic insulation also improves comfort and soundproofing.

Insulating the attic is one of the simplest and most cost-effective ways to make your home more energy efficient. However, it’s important to choose the right type of insulation and to hire a qualified professional for proper installation.

There are many different types of attic insulation, including fiberglass batts, blown-in cellulose, spray foam, and more. Each of these insulation options has its own unique set of benefits and drawbacks.

Fiberglass batt insulation is a common choice for homeowners. It consists of fine glass fibers that are rolled into big sheets. This type of insulation offers a quick and easy DIY installation, and it’s a good choice for older homes that have little or no existing attic insulation. It’s eco-friendly, non-irritating to handle, and fire-resistant. However, it may settle over time, reducing its effectiveness.

Reflective or radiant barrier insulation is another option. It uses a foil-faced reflective layer to limit radiant heat transfer and is effective in warmer climates. It can be combined with other insulation to boost its R-value, and it’s moisture-resistant. However, it can become less effective if it’s not kept clean from dust and dirt buildup.

Blown-in cellulose is another popular attic insulation option, particularly for new construction or retrofits. It’s made from recycled paper or plant-based materials and treated with fire retardants. It can be blown or sprayed into attics, and it provides an excellent R-value for a relatively low price. It’s also moisture-resistant and has good fire resistance.
