What Types of Attic Insulation Are Best?

A well-insulated attic reduces heating and cooling costs significantly. It traps the heat inside during winter and keeps it out in summer, stabilizing indoor temperatures throughout the year. It also prevents energy waste by reducing the strain on HVAC systems and prolonging their lifespan.

The best insulation for your attic depends on your specific climate zone and needs. Professionals can recommend the right insulation material for your home. They’ll ensure even coverage and proper sealing of gaps, optimizing your investment.

How TCS Insulation & Coatings Delivers Energy Savings with Attic Insulation

Fiberglass batt insulation looks a bit like cotton candy or clouds and is the most popular attic insulation option. It’s quick and easy to install, inexpensive, and comes in various thicknesses and widths with or without a paper facing. It’s best for attics with standard joist spacing, few obstacles to work around, and sufficient headroom for maneuvering during installation.

Mineral wool insulation, also called rock mineral wool, is composed of rock mineral materials and offers better thermal resistance than fiberglass. It’s also resistant to moisture and can reduce outside noises. However, it doesn’t mix well with water and may require special care if it gets wet.

Spray foam insulation is made of closed-cell or open-cell foam that expands and creates a vaulted ceiling seal. It offers superior insulation and air sealing and is often recommended by professionals, together with a new roof. It’s hard to remove once it hardens, so it’s typically used in attics with a long-term plan for its use.
