Suburbs and Rural Lots South of Town
Spray Foam Insulation in Blair Township covers suburban homes around Grawn and Chums Corner and rural houses and outbuildings farther south. Blair was formed in 1867 from part of Traverse Township and named for Austin Blair, Michigan's Civil War governor. It had 8,994 residents at the 2020 census, up from 8,209 in 2010.
Places in the township
Chums Corner is where US 31 meets M-37, and Grawn is a census-designated place where US 31 meets Silver Lake Road. Silver Lake, shared with Garfield Township, is the township's largest lake, and the Boardman River briefly crosses its northeast corner. Turtle Creek Stadium, home of the Traverse City Pit Spitters, is in the township.
Homes
Much of the housing is newer, built as Traverse City grew south. Those homes usually need rim joist foam, attic sealing and bonus-room floors. Older rural homes need attic depth, rim foam and sometimes wall filling.
Outbuildings
Rural lots often have pole barns and detached garages. Closed-cell foam on steel stops condensation and lets owners heat a shop.
Zone 6
Grand Traverse County is in Climate Zone 6A, with an attic target of R-60.
Silver Lake homes
Houses around Silver Lake, shared with Garfield Township, include older cottages and newer year-round homes. Cottages there usually need the crawl space or floor and rim sealed first; newer homes need their rims and garage ceilings done. Damp air off the lake makes closed-cell foam the better choice on any cold foundation surface.
Basements in new homes
Many newer Blair Township homes have full basements that owners finish later. Foaming the rim and walls before framing is the cheapest time to do it.
