Portucana Construction Services - Agricola Project, Halifax — Soundproofing Multi-Unit Residential Building on a Busy Street

To control impact noise, SONOpro Soundproofing Membrane, a thin, flexible layer designed specifically for floors, was applied to the second and third floors. This membrane absorbs and diffuses vibrations from footsteps and movement before they travel into lower levels. For airborne sound control, SONOpan Soundproofing Panels, 3/4-inch thick recycled wood fiber sheets with textured impressions for broad-frequency absorption (STC 27 standalone), were installed within shared and demising walls, effectively disrupting sound waves and minimizing transmission between rooms. Additional measures included high-density batt insulation for resonance reduction, double 5/8” drywall layers to increase mass and improve ratings, and resilient channels to decouple drywall from framing. Together, these materials created a durable, high-performance sound barrier across both walls and floors.
