Spray Foam Insulation in Kenhorst, PA

Spray Foam Insulation in Kenhorst works on homes in a small, settled borough. Kenhorst was founded on August 25, 1931, and grew from 2,227 residents in 1940 to 3,482 in 1970 before settling at 3,001 in the 2020 census. It covers about 0.59 square miles of land with 1,248 housing units.

Homes from the 1930s to 1970s

Kenhorst filled in between the 1930s and 1970, and homes from that period usually have thin attics, bare rim joists and walls with little insulation. Attic sealing, cellulose to depth, rim foam and dense-pack walls are the usual plan.

Few empty homes

The 2020 census found 3.8% of housing units vacant, with a homeowner vacancy rate of 1.9%. Most homes are lived in and heated year-round.

Busy roads

PA 625 runs along New Holland Road through the center, U.S. 222 Business follows Lancaster Avenue, and PA 724 runs along Philadelphia Avenue on the south edge.

Code and zone

Pennsylvania's 2021 UCC took effect January 1, 2026. Berks County is in PHRC's Central zone and OpenEI's Zone 5A. DOE recommends R-60 for an uninsulated Zone 5 attic, or adding R-49 over 3 to 4 inches.

A typical Kenhorst job

For a 1950s single or twin, a common plan is: seal the attic floor, blow cellulose to depth, foam the rim joist and dense-pack empty walls.

Old-house cautions

We check for knob-and-tube wiring, vermiculite and chimney gaps before insulating older homes. Live old wiring should not be buried, and vermiculite should be tested first.
