Insulation in Irvington, NJ

Insulating homes and buildings in Irvington

Irvington's housing stock is dominated by densely spaced two- and three-family homes, many of them a century old. In buildings like these, stack effect is the dominant force: warm air rises through open wall cavities, stairwells and chases, escapes through the attic, and pulls cold air in at the basement to replace it. Adding attic insulation without first sealing that path gives disappointing results, which is why so many owners here have insulated once already and seen little change.

We work the sequence in the right order — seal the top plates, chases, plumbing stacks and attic hatch first, then insulate. On the buildings we treat this way, owners consistently report that the top floor stops overheating in summer, which is usually the complaint that prompted the call.

For landlords and property managers, the second benefit is sound. Open cell foam in the floor cavities between units meaningfully reduces noise complaints between tenants, and it can be done unit by unit as apartments turn over rather than all at once.
