Targeted Multi-Unit Expertise.
We deploy our specialized drywall and insulation crews across a precise spectrum of multi-residential developments. If you are building high-yield rental units or mid-rise complexes, we are your scalable solution.
MULTI UNIT RENTAL
Purpose-built rentals, duplex conversions, and missing middle housing. We understand the tight margins and aggressive timelines required for rental ROIs. Our crews deliver fast, durable finishes that stand up to tenant turnover while strictly adhering to inter-unit STC fire separation codes.
LOW RISE
Townhouse complexes, stacked layouts, and subdivision phases. We shine when managing repetitive floor plans at high velocity. Rozi Contractors guarantees a predictable rhythm of sprayfoam, boarding, and taping across multiple blocks simultaneously, eliminating typical sub-trade bottlenecks.
MID RISE
Four to ten-story wood-frame or light-gauge steel boutique builds. Mid-rise projects demand rigorous fire stopping, structural coatings, and complex corridor separations. Our fully insured commercial-grade crews handle the logistical scale and stringent building code requirements flawlessly.
BUILDING THE ENVELOPE.
We don't just do tasks; we execute phases. By combining material take-offs, insulation, and hanging into one master schedule, we eliminate the friction between trades.
Pre-Construction & Estimating
We start with a meticulous material take-off, value-engineering your prints to find efficiencies in STC assemblies and fire separations. During this phase our estimator will advise you on the most cost-effective options to meet OBC standards.
Batt Insulation
Precision-cut batt insulation installed in party walls, exterior envelopes, and ceilings with complete vapour barrier coverage. Rockwool Safe'n'Sound for party walls to exceed minimum STC ratings.
Sprayfoam Insulation
Rapid 2lb closed-cell sprayfoam application for exterior walls and headers, creating a perfect air and moisture seal. Our large crews insulate entire floors in a single pass for maximum schedule efficiency.
Acoustic Insulation
Resilient channels, acoustical sealants, and Sonapan/Rockwool Safe'n'Sound installed to achieve elite STC and IIC ratings between units. Critical for multi-residential code compliance and occupant comfort.
Drywall Hanging
Installation of heavy-duty Type-X/Fire-Rated drywall across all units. Our crews execute high-speed boarding with precision cutting and fastening to maintain tight schedules across multi-floor builds.
Taping/Smooth Finish
Level 4 standard taping and fire-taping to seal partitions efficiently. We also offer Level 5 skim coat for lobbies, hallways, and high-visibility common areas.
Fire Coating DC315
Code-compliant DC315 intumescent fire coating, red tube firestop sealants, and intumescent coatings applied to exposed sprayfoam, structural elements, basements, and mechanical rooms.
Delivery & Hand-off
Our in-house team performs a thorough quality check to ensure no areas are missed. We perform touch-ups of our work and a complete site clean-up. We hand over units precisely on schedule, ready for paint.
