Spray Foam Insulation in Spring Township, PA

Spray Foam Insulation in Spring Township mostly involves suburban homes built since 1980. The township grew from 17,193 residents in 1980 to 27,119 in 2010, including a 24.4% jump between 2000 and 2010, and the 2020 census counted 28,396, making it the second most populous municipality in Berks County after Reading.

Newer homes

Colonials and two-stories from the 1980s through the 2000s usually have some attic insulation, plus bare rim joists, leaky hatches and bonus rooms over garages. Attic sealing and top-up, rim foam and bonus room work are the usual plan.

Large footprint

The township covers about 18.5 square miles from the Schuylkill River area to the Lancaster County line, and was formed from Cumru Township in 1850. Older farmhouses and houses along the old roads need the full old-house treatment.

Retail and parks

Spring Township shares Reading's western suburban retail district with Wyomissing, from the Berkshire Mall to the Spring Ridge Drive exit off U.S. 222.

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 Spring Township job

For a 1990s two-story, a common plan is: seal and top up the attic, foam the rim joist, and fix the bonus room with floor foam and kneewall sealing. For an older farmhouse, add wall dense-pack and sill foam.
