Commercial Fire-Resistant Drywall Installation

We install code-approved fire-rated drywall for commercial safety.

Commercial Fire-Resistant Drywall Installation for Safer Interiors

 

Commercial fire-resistant drywall installation plays a vital role in meeting today’s building code requirements. Whether you’re constructing demising walls between retail spaces or enclosing stairwells and elevator shafts, fire-rated assemblies are often a legal necessity.

At Express Drywall Services, we install UL- and GA-approved assemblies using Type X and Type C boards. These systems help slow fire spread, protect structural elements and create safe egress paths. We follow specific fastening, layering and joint treatment guidelines to preserve the rated performance.

Our team is experienced in working around plumbing, HVAC and electrical trades to ensure seamless coordination. If your project also includes moisture-prone areas, we can combine fire-rated drywall with moisture-resistant drywall and tile backer solutions. We also offer sound separation systems for multi-tenant buildings to meet both acoustic and fire safety needs. Each installation is inspected internally before sign-off to reduce risk of inspection delays.

Fire Code Upgrades

Commercial fire-resistant drywall installation is essential in spaces where safety and code compliance are non-negotiable. It’s required for stairwells, elevator shafts, demising walls and fire-rated corridors – anywhere that a proper fire separation is mandated. It’s also used between tenant units, storage rooms and mechanical enclosures.

This material helps contain fire, slow its spread and provide safe egress during emergencies. If you’re working on a multi-unit residential complex, retail center or institutional building, fire-rated assemblies may be mandatory. Choosing the right assemblies and certified installers is key to passing inspections and keeping occupants protected.

Fire-Rated Systems That Integrate With Framing, Insulation & Finish Work

For developers and builders working on multi-unit residential or mixed-use complexes, commercial fire-resistant drywall installation is more than a safety feature – it’s a requirement. We specialize in installing fire-rated assemblies between dwelling units, service corridors, mechanical rooms and storage spaces.

Our crews ensure that the framing is prepped and backed properly before fire-rated boards go up and we coordinate closely with framing teams to avoid rework or missed inspections. When the project includes acoustic requirements, we incorporate resilient channel systems or sound-rated insulation to meet STC targets alongside fire ratings.

We also handle insulation installation where thermal or fire barriers are needed behind drywall layers. After boarding, our finishers apply fire-compatible compounds and complete commercial taping and mudding to level-appropriate standards. We’re used to working under pressure and can adapt to tight schedules common in high-density builds.

Our team maintains clean, organized work zones and leaves every space finish-ready for painters or ceiling trades. If you’re also updating T-bar ceilings or drop ceilings, we’ll ensure transitions are smooth and compliant.

From Code Requirements to Clean Finish

Our Commercial Fire-Resistant Drywall Installation Process for Projects

We begin with a detailed walkthrough to review plans, rated assemblies and project specifications. Our team identifies where fire-rated assemblies are required based on local code and UL guidelines. We assess site conditions, access points and staging needs. This ensures all fire-rated walls and ceilings are properly scoped and documented before materials arrive.
We coordinate delivery of Type X or Type C drywall, specialty fasteners, mineral wool insulation and fire caulking as required. All materials are matched to UL assembly numbers and stored for efficient access. We schedule deliveries around other trades to avoid congestion and delays. Every item is checked for compliance before it hits the wall.
Framing is verified or adjusted to meet fire-rated requirements, including stud spacing, height limits and approved backing. Blocking for fixture penetrations or multi-layer assemblies is installed at this stage. We ensure penetrations are accounted for with proper firestopping solutions. Coordination with mechanical and electrical subs happens here to prevent rework.
Fire-rated boards are installed to match the specified UL or GA assemblies. This includes correct orientation, offset seams, screw spacing and layering sequence. We follow strict fastening and jointing requirements to maintain full fire-resistance performance. Our crews document installations as needed for future inspection or recordkeeping.
Our finishers apply multi-stage taping systems suited to fire-rated joints, followed by proper sanding and feathering. We use fire-resistant compounds where required. All finish work is done to level-appropriate smoothness, based on the project’s visual or functional requirements. The end result is a compliant, clean surface ready for painting or further treatment.
We conduct a final inspection to confirm all fire-rated elements are installed per code and assembly specs. Any penetrations or variances are sealed or flagged for fire caulking. Cleanup includes removal of dust, debris and excess materials, leaving the space ready for follow-up trades. We assist in preparing documents or walkthroughs for city or third-party inspection teams.

Fire Separation Done Right in Offices, Retail & Institutional Spaces

Fire-rated drywall installation plays a key role in commercial tenant improvements, offices, educational spaces and retail fit-outs. Whether you’re dividing lease areas or upgrading existing walls to meet fire code, our team can deliver clean, code-compliant results. We begin by reviewing plans and confirming UL assembly numbers for each wall type, from one-hour separations to two-hour shaft walls.

Our scope often includes steel stud framing, commercial drywall installation and fire caulking in areas with pipe or duct penetrations. If your site includes wet zones like washrooms or kitchens, we can transition to moisture-resistant drywall and include tile backer board installation where needed.

We also help update older assemblies to meet new fire code or lease compliance requirements. For corridors and common areas, we maintain seamless finishes that are ready for priming and painting without touchups. We adapt to off-hours or staged work zones to avoid disruption in operating facilities.

If acoustic privacy is a concern, we can include sound-rated wall systems alongside your fire assemblies.  With Express Drywall Services, you get more than a compliant wall – you get a partner in building safe, functional spaces that last.
