Multi-family buildings stack the usual envelope problem with a neighbour problem: every unit shares walls and floors, so thermal comfort, sound transfer and fire separation all matter at once. Spray foam contributes to each - whole-building air-sealing plus performance at the demising assemblies.
Two jobs in one building
- Whole-building envelope: air-sealing the exterior walls, roof and rim reduces the heating load and the drafts that generate tenant complaints across every unit.
- Between-unit assemblies: foam in demising walls and floors improves sound separation and contributes to the assembly performance the code requires (finished with the required thermal barrier).
Why it scales well
One continuous air-seal across a building is more effective and consistent than unit-by-unit patching, and it pays back across every suite at once. Works for condos, walk-ups, townhome rows and apartment blocks.
