Where Your Home Loses Heat

Select an area on the drawing to see where heat escapes and how we fix it.

Section A–A · Two-storey home, basement and crawl space

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.
