Spray Foam Insulation in East Hempfield, PA

Spray Foam Insulation in East Hempfield Township spans a growing suburb west of Lancaster. The township covers 21.1 square miles and includes Mechanicsville, Landisville, Bamford, Centerville, Chestnut Ridge, Rohrerstown, Donerville, Chestnut View, Wheatland and part of Salunga. Its population reached 26,350 at the 2020 census, up from 21,399 in 2000, when 8,761 housing units were counted.

Old and new side by side

Growth means new subdivisions next to older farmhouses. The Amos Herr farmhouse in the township park dates to 1852. Older farmhouses need attic sealing, rim work and careful handling of stone foundations; newer houses need rooms over garages, cathedral ceilings and basements handled.

Newer construction

Even new houses leak at predictable spots: attic hatches, recessed lights, rim joists covered only with batts, and the floors of bonus rooms. Foam on the rim and under bonus room floors, plus attic sealing, usually fixes the comfort complaints.

Zone 5

Lancaster County is in Pennsylvania's central Zone 5 group. ENERGY STAR recommends adding R-49 over three to four inches of existing attic insulation in zone 5.

Outbuildings

East Hempfield still has farm properties and large lots with detached garages and shops. If you plan to heat one, closed-cell foam on the walls and roof is the usual approach; it insulates and stops condensation on steel or wood.

Order of work

If you are planning several projects, the order matters. Air sealing and attic work before a new HVAC system lets the contractor size the equipment to a tighter house.
