Drywall & soundproofing
Metal studs, drywall partitions, suspended ceilings and sound insulation for offices and retail stores, under direct contract or as a subcontractor for general contractors.
Interior systems are the non-load-bearing part of the building: the partition framing, the drywall, the ceilings and the acoustic insulation. They give an office or a store its layout, its acoustic comfort and its finish.
I
We work for owners and property managers, and as a subcontractor for other general contractors.
Light galvanized metal studs that form the partition framing. Straight and stable, they suit adaptable offices, clinics and stores that will evolve. Layout according to the plans, tracks, studs, blocking for door frames, bulkheads and soffits.
Drywall on one or both sides, in one or more layers, depending on the assembly required: regular drywall, moisture-resistant for wet rooms, or type X for the fire separations shown on the plans. Cut-outs and coordination with the other trades.
A metal grid hung from the structure with removable tiles: the ceiling hides the ducts and wiring while keeping them accessible, and integrates the light fixtures and ventilation diffusers.
Sound insulation in the cavities of partitions and ceilings, matched to the stud depth (3 5/8 in. or 6 in.). Final performance depends on the complete assembly: layers of drywall, sealed joints, treatment of openings.
Tape, several coats of compound and sanding for a uniform surface, then primer and paint. It is the most visible step: we do it with care, protecting floors and existing surfaces.
From your plans, your schedule and your site instructions. Work not provided for in the contract is the subject of a separate written offer, prepared after a visit and a review of the plans, with the applicable administration fees. Quantities validated by the architect when needed.
II
What our clients most often trust us with in interior systems.
New partitions, a suspended ceiling, integrated lighting: we carry out the architect's plans and coordinate with electrical and ventilation.
Meeting rooms, clinics, dwellings: the acoustic assembly defined in the plans is installed with the insulation, drywall layers and sealed joints it calls for.
A general contractor receives an instruction during the contract: we visit, price it in writing and carry it out within their schedule, without delaying the job.
III
From the plans to acceptance, keeping to the job schedule.
IV
A subcontractor who knows a general contractor's constraints, because it is one.
The fire resistance and acoustic performance of a partition depend on the complete assembly shown on the plans, not on a single material.

Interior systems vocabulary, as it is used on Quebec job sites.
V
We build interior systems and do soundproofing work in Montreal, on the North Shore, including Laval, and on the South Shore.
VI
Yes. We do metal stud, drywall, suspended ceiling and soundproofing work for general contractors, from their plans and site instructions.
Each extra is the subject of a separate written offer, based on a visit and the plans. Quantities can be validated by the architect, and nothing is carried out before it is signed.
It reduces part of the noise, but performance depends on the whole assembly: layers of drywall, sealed joints, doors and openings. For a specific acoustic target, the assembly is defined in the plans by the project's professional.
Yes. We install dust partitions, protect the entrances and plan the noisy phases with you to limit the impact on your operations.
The National Building Code, applied in Quebec through the Construction Code, requires walls and floors separating two dwellings to reach a sound transmission class (STC) of at least 50, or an apparent STC (ASTC) of at least 47, which takes adjoining construction into account. The Code sets no requirement for impact noise, such as footsteps: an IIC of at least 55 is often recommended for occupant comfort.

Our prices are based on the current wage rates of the Commission de la construction du Québec (CCQ), set by the collective agreements for the sector concerned (residential, institutional and commercial, industrial), plus the materials and equipment specific to each job. Every quote is free, detailed and prepared after a site visit.
Metal studs are straight, light and non-combustible: they are the usual choice in offices, retail stores and institutional buildings. Wood remains common in residential work. For soundproofing, the framing matters less than the complete assembly: insulation, number of drywall layers, resilient channels and sealed joints.
