Why Choose Batt Insulation?

Batt insulation is a reliable and cost-effective option for improving thermal performance in walls, ceilings, and other framed areas. It is commonly used in both new construction and renovation projects because it fits standard stud and joist spaces well and provides consistent insulation coverage throughout the building.

It is a popular choice for homeowners and builders looking for an efficient insulation solution that supports indoor comfort and helps reduce heat loss. When properly installed, batt insulation can contribute to better energy performance and a more comfortable living environment year-round.

Where Does Batt Insulation Work Best?

Batt insulation works best in framed wall cavities, ceilings, floors, and other open spaces where standard-sized insulation can be installed efficiently. It is especially well suited for new builds, basement finishing, additions, and renovation projects where accessible framing allows for clean and effective installation.

Because it is designed for structured spaces, batt insulation is a strong option when the goal is dependable thermal performance, affordability, and straightforward installation. It is often used as part of a complete insulation system to improve comfort and overall energy efficiency throughout the home or building.

Attic

Blown-in insulation tops up existing attic insulation without major disruption, settling around framing, corners and uneven areas. Batt insulation fits standard joist spaces in ceilings.

How we fix it

Exterior walls

Spray foam expands as it’s applied, sealing gaps and cracks to help reduce drafts and air leakage. In framed walls, batt insulation fits standard stud spaces for dependable thermal performance.

How we fix it

Rim joists

Rim joists are among the areas where air leakage and heat loss are most likely to occur. Spray foam combines insulation and air sealing in one application.

How we fix it

Basement walls

Basements can account for about 25% of a home’s total heat loss. Spray foam is a strong choice for basements, combining insulation and air sealing in one application.

How we fix it

Crawl space

Spray foam is especially effective in hard-to-insulate spaces like crawl spaces, where thermal performance and air sealing both matter. It expands to seal gaps and cracks, helping reduce air leakage.

How we fix it

Old insulation

Over time, insulation can become compacted, damaged or contaminated, and its performance can decrease. We remove it with industrial vacuum systems so the space can be inspected and prepared before re-insulating.

Older materials such as vermiculite may require testing or a specialized assessment before removal, due to the potential presence of asbestos.
