Spray Foam Insulation in Westland, MI

Spray foam insulation in Westland often starts with homes that were built quickly. Wikipedia notes that Nankin Township, which became Westland, was mostly rural until World War II. The Norwayne subdivision, one of the oldest areas of the city, was built right after the war as temporary housing for returning soldiers who worked in nearby factories. By 1960 the township had about 70,000 people, making it the largest township in the state at the time.

Small houses, big leaks

Post-war houses built for speed tend to have thin walls, shallow attics and simple construction. That makes them easy to improve. A sealed attic floor with fresh blown insulation, closed-cell foam on the rim, and filled walls can change how a small house feels in January.

Later subdivisions

Westland kept growing through the 1960s and beyond. Later homes have more insulation but still leak at rim joists, attic hatches, bath fans and rooms over garages. We check those first.

Numbers

The 2020 census counted 39,633 housing units in Westland, 4.9% vacant. Westland is in Wayne County, listed in Climate Zone 5A in Michigan's energy code. DTE's rebate page lists amounts for attics, walls and rim joists for homes it heats.

Ductwork in unheated spaces

Some Westland homes, especially those built on slabs or crawl spaces, run heating ducts through the attic or a vented crawl. Ducts in unheated space lose heat before it reaches the rooms. Sealing duct joints and either insulating the ducts or bringing them inside the insulated shell, for example with foam on the roof deck or crawl space walls, can make the far rooms warmer. We note where ducts run during the visit.

Small attic access

Post-war homes often have tight attics with low headroom. That limits what can be done safely by hand, and it is one reason we blow loose fill into those spaces after sealing, rather than laying batts.
