Fire Separation Requirements

Multi-unit buildings require fire-rated separations between dwelling units. Ontario Building Code mandates specific fire resistance ratings (typically 1-hour or 2-hour) for party walls, floor/ceiling assemblies, and certain structural elements. Many multiplexes use CFS (cold-formed steel) framing for fire-rated assemblies - we supply and install steel studs with our own in-house takeoffs, giving you competitive pricing and accurate material quantities. For enhanced fire protection, we also offer spray-applied fireproofing and firestop services.

Built-Up Beams & Complex Fire Details

One of our specialties is installing built-up beams (box beams) along the perimeter of subfloors for fire separation purposes. We assemble these beams by hand on-site to ensure precise fit and proper fire blocking. This critical detail prevents fire spread between units at floor assemblies - a requirement that many framers overlook or execute poorly. No matter how complex your fire separation details are, we can take care of it. From intricate party wall intersections to stepped floor assemblies and mechanical penetrations, our crews have the experience to frame it right the first time. Complex details don't intimidate us - they're where our expertise shines.

CFS Supply & Install

For multiplexes requiring cold-formed steel framing, we provide complete supply and install packages at the lowest market rates. Our team performs CFS takeoffs in-house - no third-party estimators or middleman markup on materials. We buy steel studs, track, and accessories at contractor pricing and pass those savings to you. Whether your multiplex uses CFS for load-bearing exterior walls, party walls, or both, you get competitive pricing with single-source accountability. We also install steel beams and moment frames for structural support.

Sound Control in Multi-Unit Buildings

Sound transmission between units is a major concern in multiplexes. Effective sound isolation starts with framing design - staggered stud walls, resilient channels, and proper detail at connections all contribute to acoustic performance. We frame party walls and floor assemblies to accept sound-reducing insulation and achieve the STC ratings your tenants expect. For complete acoustic solutions, explore our soundproofing services which pair perfectly with proper framing techniques.
