Perry Homes and Farms
Spray Foam Insulation in Perry covers a railroad town on US-24 between Lawrence and Topeka. Perry got its start in 1865 when the railroad came through, incorporated in 1871 and is named for Kansas Pacific Railroad president John D. Perry. It lies on the Delaware River a few miles south of Perry Dam, whose reservoir first filled in January 1969.
An older population
Perry's median age rose from 37.1 in 2010 to 43.4 in 2020, and 23.0% of residents were 65 or older. Lower bills and steadier temperatures are common goals, and sealing plus attic depth deliver both.
Older homes
Town homes typically need rim joist foam, attic sealing and depth, and sometimes dense-pack walls.
Farms
Farmsteads and acreages around Perry have pole barns and machine sheds. Closed-cell foam makes them heatable and stops drip.
Code targets
Jefferson County is in climate zone 4A. ENERGY STAR recommends R-60 for an uninsulated attic and R-49 added over 3 to 4 inches.
Rebates
If Evergy is your electric provider, its Kansas chart lists rebates for air sealing, R-38 ceiling insulation and rim joist work.
Typical quote
A line for the rim, a line for attic sealing and depth, and one for any outbuilding, so you can choose what to do now.
Lake area
Perry Lake to the north is a Corps of Engineers flood control reservoir. Homes and cabins near it often have crawl spaces and vaulted ceilings that benefit from closed-cell foam.
Climate
Jefferson County winters bring cold snaps and occasional snow; Oskaloosa, just up the road, has a local record of -24F. A sealed rim and attic keep the furnace from running nonstop.
