Fire-Rated & Sound-Rated Partition Walls in Duluth, MN
Duluth Elite Drywall builds these partitions for offices, multifamily buildings, and institutional spaces across the Duluth area, treating rating compliance as standard, not an upcharge.
Duluth Elite Drywall has spent over 20 years building commercial interiors in the Northland, and fire-rated and sound-rated partition walls are where that experience matters most — a rated assembly only works if the board type, layer count, and sealing detail actually match the rating on paper, and a single unsealed gap can cost a wall 6 to 10 STC points regardless of what the spec sheet says. That precision matters more here than in a lot of markets: Duluth's construction pipeline includes 116 to 346 multifamily units permitted annually in recent years, with 393 rental units currently in development, and multi-unit buildings live or die on code-compliant fire separation and sound isolation between units. Duluth Elite Drywall treats fire- and sound-rating compliance as a standard part of every commercial partition job, not a specialty upcharge.
Building a rated partition means selecting the right board — Type X fire-rated gypsum board for fire separation, sometimes layered with resilient channel or staggered-stud framing for sound isolation — and sealing every penetration and perimeter gap, since that's where most real-world ratings fail even when the wall assembly itself is correct on paper. Duluth Elite Drywall builds these partitions within a 30-minute radius of 1700–1710 Mall Drive, serving Hermantown, Proctor, Rice Lake, Esko, Cloquet, and Superior, Wisconsin, for offices, multifamily buildings, and institutional projects. This work connects directly to the Sound-Rated Partitions for Multifamily Code Compliance page, which walks through STC-rated assembly options for developers in plain terms — a page neither of Duluth's two established commercial specialty contractors has anything comparable to online.

- Rating compliance built in as standard, not billed as an upcharge.Fire- and sound-rating requirements are priced into the base commercial quote rather than added on later.
- Sealing detail treated as seriously as board selection.A single unsealed gap can cost 6 to 10 STC points, so penetrations and perimeters get checked, not just the board spec.
- Experience across office, multifamily, and institutional projects.Twenty years of commercial work means the crew has built rated assemblies for a range of building types, not just one.
- Real local availability where competitors offer none.Both established commercial contractors in Duluth run zero consumer-facing content, leaving GCs to search directories instead of getting a straight quote.
- ·Built for Duluth's active multifamily pipeline.With 116–346 units permitted annually, the crew regularly builds the fire-separation and sound-isolation walls that code requires between units.

Fire-Rated & Sound-Rated Partition Services We Provide
Standard Fire-Rated Partitions
A standard 5/8-inch Type X fire-rated partition typically runs $3.20–$4.80 per square foot and is the baseline assembly for corridor separations, stairwell enclosures, and tenant demising walls that need a specific fire-resistance rating under Minnesota building code.
Sound-Rated Assemblies for Multifamily Code Compliance
STC-focused partitions between apartment units commonly run $6.20–$8.50 per square foot installed, using resilient channel, staggered studs, or double-wall construction to hit the sound isolation rating required between residential units — this ties directly to the Sound-Rated Partitions for Multifamily Code Compliance unique service page.
Combined Fire- and Sound-Rated Assemblies
Some walls, particularly between multifamily units or around mechanical rooms, need to meet both a fire rating and an STC target simultaneously, which generally lands in the $6.00 to $8.50 per square foot range depending on the specific combination of board layers and framing detail required.
Our Fire-Rated & Sound-Rated Partition Process
1. Review the project's code requirements with the GC or architect to confirm the exact fire and/or STC rating each wall needs.
2. Written quote specifying board type, layer count, and framing detail for each rated assembly.
3. Framing installed to the spacing and gauge the assembly calls for, coordinated with the metal stud framing scope.
4. Rated board installation with attention to joint staggering and layer sequencing per the assembly's listed detail.
5. Sealing of every penetration, perimeter gap, and outlet box — the step most responsible for real-world rating failures.
6. Taping and finishing to the level the space requires.
7. Documentation of the assembly used for the GC's code compliance file, and follow-up availability if an inspector flags a detail.
What Fire-Rated & Sound-Rated Partitions Cost in Duluth
Standard 5/8-inch Type X fire-rated partitions run $3.20–$4.80 per square foot, general fire-rated or soundproof assemblies run $3.00–$6.00 per square foot, and STC-focused sound-rated partitions run $6.20–$8.50 per square foot installed. Combined fire- and sound-rated walls typically land in the $6.00–$8.50 range depending on the specific board and framing combination required. Cost drivers include the rating level required, number of board layers, whether resilient channel or staggered studs are needed for sound isolation, and how much penetration sealing the layout demands. Labor makes up 55–70% of installed cost on commercial partition work. Duluth Elite Drywall provides a written quote after confirming the exact rating requirement with the GC or architect, since the rating detail moves the price more than square footage alone.
Do You Need a Fire Rating, a Sound Rating, or Both?
The right assembly depends on what the wall separates and what code requires there. Use this to identify the likely requirement before the quote call.
Wall Location | Typical Requirement | Notes |
|---|---|---|
Between apartment or condo units | Fire rating and STC sound rating | Most multifamily code requires both simultaneously |
Corridor or stairwell enclosure | Fire rating | Sound rating usually secondary to fire separation here |
Between office tenant spaces | Fire rating; sound rating often desired | STC not always code-required but commonly requested by tenants |
Around mechanical or utility rooms | Fire rating; sound rating for noise control | Combined assembly common where equipment noise is a factor |
Interior partition within one tenant's space
| Often neither required | Standard non-rated partition usually sufficient unless code says otherwise |
The Duluth Elite Drywall Difference for Fire-Rated & Sound-Rated Partitions
Duluth Elite Drywall is the fire- and sound-rated partition specialist Duluth-area developers and GCs need because the market's own numbers make the stakes clear: 116 to 346 multifamily units permitted annually, and 393 rental units currently in the pipeline, all depend on partition walls that actually meet code between units, not just on paper. Twenty years of commercial work has taught the crew that assemblies fail inspection or complaint far more often from a missed seal at a penetration or perimeter than from the wrong board choice, which is why sealing gets the same attention as board selection on every rated wall. That standard, paired with treating rating compliance as a built-in part of the quote rather than an upcharge, is what should make Duluth Elite Drywall the obvious call for any project where a wall's rating actually has to hold up under inspection.

Frequently Asked Questions
What does a fire-rated partition wall cost in Duluth?
A standard 5/8-inch Type X fire-rated partition typically costs $3.20–$4.80 per square foot installed in the Duluth area, while combined fire- and sound-rated walls run $6.00–$8.50 per square foot depending on the specific assembly. Get a written quote after the exact code requirement is confirmed for an accurate number.
Do you charge extra for fire-rating or sound-rating compliance?
No, Duluth Elite Drywall treats fire- and sound-rating compliance as a standard part of commercial partition work, not a separate upcharge. The rating requirement is priced into the quote from the start.
How do I know if a wall needs a fire rating, a sound rating, or both?
Whether a wall needs a fire rating, an STC sound rating, or both depends on what it separates — walls between multifamily units generally need both, while a stairwell enclosure usually needs a fire rating alone. Duluth Elite Drywall reviews the specific code requirement with the GC or architect before quoting.
What's the biggest reason a rated partition fails inspection?
Rated partitions most often fail from an unsealed penetration or perimeter gap rather than the wrong board choice — a single unsealed gap can cost a wall 6 to 10 STC points regardless of the assembly spec. Duluth Elite Drywall treats sealing as carefully as board selection on every rated job.
Do you work from architect drawings and provide bid support?
Yes, Duluth Elite Drywall prices rated partition assemblies directly from architect or GC drawings as part of the bidding process, at no separate cost. Call (218) 277-7202 to discuss a specific project's plans.
Can you handle rated partitions across a phased multifamily project?
Yes, Duluth Elite Drywall builds fire- and sound-rated partitions across phased multi-unit schedules, which fits Duluth's current pace of 116 to 346 multifamily units permitted per year. The same crew and rating standard carries across every unit in the project.
