Lab and Cleanroom Drywall Buildout in New Haven’s Life-Science Corridor
New Haven has quietly become one of the Northeast’s faster-growing biotech hubs. 101 College Street and 100 College Street, the Alexandria and Winstanley life-science towers, plus the older Science Park corridor have pulled a wave of lab tenants into the city, and every one of them needs a shell turned into working lab space on a hard timeline. Lab drywall is not office drywall with a different paint color. The tolerances are tighter, the board has to take abuse and wash down, the schedule is dictated by equipment that has already been ordered, and the wall has to coordinate with more mechanical systems than almost any other interior build.
Lab and cleanroom drywall buildout is commercial interior framing and board work executed to the heightened tolerance, durability, and cleanability standards lab space demands. It runs from metal stud framing with backing for benches, hoods, and equipment, through impact- and abuse-resistant or moisture-tolerant board where the environment calls for it, to high-flatness finishing and, for controlled environments, monolithic, gasketed, washable wall assemblies rather than conventional taped gypsum. The work is sequenced tightly with lab MEP, casework, and equipment delivery so the space is ready for fit-out on the tenant’s schedule.
Tolerances, durability, and cleanability
A bench lab runs carts, rolls equipment, and gets scrubbed. Equipment corridors and high-traffic walls get impact- and abuse-resistant board rated to ASTM C1629 (National Gypsum Hi-Impact, CertainTeed Extreme) so a cart corner does not punch the wall in month two. Wet labs and wash-down areas get moisture-tolerant board (USG Mold Tough, Fiberock). Where the finish schedule calls for an epoxy or high-sheen coating, common in tissue culture and instrument rooms, the wall gets finished to Level 5 flatness so the coating does not telegraph every seam and fastener under flat lab lighting. Reading the wall-type schedule and putting the right assembly in each room, rather than hanging standard gypsum everywhere, is the difference between a lab that holds up and one that is getting patched within a year.
Controlled-environment and cleanroom-adjacent walls
When a project includes controlled-environment or cleanroom-adjacent space, ordinary taped-and-painted gypsum does not qualify. Those rooms need monolithic, gasketed, washable wall assemblies with sealed transitions and no particle-shedding details. Those systems are installed to the manufacturer’s cleanroom detail and the lab planner’s drawings. The full cleanroom (HVAC, filtration, particle-count validation against ISO 14644) is the integrator’s scope; what the drywall sub delivers is the wall system that environment is built on, detailed correctly so it passes.
Coordination is most of the job
Labs are the most MEP-dense interiors there are: lab gas, deionized water, exhaust and fume-hood ducts, heavy power, and data, all converging in the walls and ceiling. Framing sequences around that rough-in, in-wall backing is set for fume hoods, wall-hung benches, monitors, and shelving before anything is closed, and chemical-occupancy and shaft separations are built to the listed UL fire-rated detail. Framing, fire-stopping, and cover inspections are scheduled with the GC and the New Haven Building Department so cover-up never gets ahead of sign-off, because the one thing a venture-funded tenant cannot absorb is a wall that has to come back open after the equipment has shipped. What the GC or tenant is buying is a wall package that hits spec, holds tolerance, coordinates cleanly with the lab systems, and is ready for the finish trade on the date the schedule needs it.

Frequently asked questions
Have you done life-science fit-outs in New Haven's lab corridor? +
Lab and controlled-environment fit-out is a core commercial scope for us, and New Haven's life-science buildings (101 and 100 College Street, the Science Park corridor) are exactly the kind of work this page is built for. We understand the tolerance, durability, and cleanability demands lab space puts on the wall assemblies, and we sequence around the heavy MEP that comes with it.
Can you hold the flatness and finish a coated lab wall needs? +
Yes. Where the spec calls for high-sheen or coated finishes, we finish to Level 5 / high flatness so the surface reads flat under lab lighting and accepts epoxy or coating without telegraphing seams. We confirm the required level from the finish schedule before we start.
Do you build cleanroom or controlled-environment walls? +
We install the monolithic, gasketed, washable wall assemblies controlled environments require, per the manufacturer's cleanroom detail and the lab planner's drawings. Full cleanroom certification and validation (HVAC, filtration, particle counts) is the integrator's scope; we deliver the wall assemblies that system is built on.
Can you coordinate around our lab MEP and equipment schedule? +
Yes, that coordination is most of the job. We sequence framing around gas, DI water, exhaust, and electrical rough-in, set backing for hoods, benches, and wall-hung equipment before closing walls, and plan the schedule against fixed equipment-delivery and occupancy dates.
Do you put the right board in the right wall, or is it all standard gypsum? +
Per the wall-type schedule. Abuse- and impact-resistant board (ASTM C1629) goes on equipment corridors and high-traffic walls; moisture-tolerant board goes in wash-down and wet-lab areas; standard board where that is all that is specified. We do not substitute down to save material cost.
Are you set up to work as a sub for our GC? +
Yes. We are CT-registered, carry commercial GL with COI on request, bond where required, and are used to itemized sub bids and inspection sequencing that will not hold up the GC's schedule.
