Wall Insulation for Rowhomes & Older Homes in York, PA

Wall insulation for rowhomes and older homes matters in York, where about half the city's houses predate 1940. Frame walls from that era were built hollow, and brick walls were built solid with no insulation at all. The front and back walls of a rowhome and the side wall of an end unit or twin are where most heat leaves.

Frame walls

In frame walls, we dense-pack cellulose through small holes from the outside or inside, then plug and patch. We check for knob-and-tube wiring, blocking and moisture first.

Brick walls

Solid masonry walls cannot be filled. Options are insulating from the inside during a remodel (foam or rigid board on furring with a new wall surface) or focusing on the roof, rim and windows instead. We explain what makes sense for your wall.

Open walls

During a remodel, open stud bays can be sprayed. Closed-cell reaches Pennsylvania's R-20 Zone 4 wall target in a 2x4 wall.

Re-siding is a good time

If you are replacing siding on a frame house, that is the easiest time to fill the walls. With the old siding off, cavities are filled through the sheathing and patched, and the plaster inside is never touched. Continuous foam board can also go on before the new siding.
