Fire-Rated Board Systems

Technical scope

Dry-construction fire encasement for structural frames, service shafts, and ducts.

Fire-rated board systems provide dry, clean, and dimensionally accurate fire separation and structural encasement without introducing water, spray equipment, or overspray contamination into the building environment.

Fabricated from non-combustible calcium silicate, vermiculite, or gypsum composite cores, board systems are particularly advantageous for clean-room installations, operational commercial buildings, electrical substation enclosures, and vertical service shafts where wet spray trades are prohibited.

Vortexen coordinates complete tested assemblies including board thickness selection, steel stud framing, corner reinforcing beads, edge screw spacing, fire-rated joint mastic, and access panel integration, ensuring full compliance with approved laboratory test assemblies.
