Cleanroom Doors, Windows and Interlock Systems
Fire-Rated Cleanroom Door
A complete hygienic steel doorset built around a dense mineral-wool core, reinforced frame and intumescent edge system for cleanroom boundaries that also require fire compartmentation.
- Mineral-Wool Insulated Leaf
- Intumescent Perimeter Protection
- Hygienic Powder-Coated Faces
- Reinforced Complete Doorset
Product Introduction
The Fire-Rated Cleanroom Door combines the smooth surfaces expected in a controlled room with the heavier leaf, frame reinforcement and heat-reactive seals used in a fire-resisting doorset. Dense mineral wool fills the steel leaf, while intumescent strips are protected within the perimeter detail. Hinges, latch, closer, glazing and frame anchors are selected as parts of one compatible assembly rather than added independently after manufacture.
Key Features
Protected intumescent strips expand under heat without creating everyday cleaning ledges.
Reinforced hinge and closer zones control the greater mass of a fire-resisting leaf.
Powder-coated galvanized faces remain smooth for routine cleanroom housekeeping.
Optional fire-resisting glazing preserves observation in compatible door configurations.
Customer Product Concerns
A fire-rated cleanroom opening must retain hygienic surfaces without weakening the complete door assembly through unsuitable seals, hardware or site modifications.
A standard lightweight cleanroom leaf does not provide the mass or edge protection needed at a fire boundary.Mineral wool, reinforced steel skins and protected intumescent seals form a purpose-built heavy-duty leaf.
Projecting fire seals create additional dirt traps around the opening.Intumescent material is recessed within a smooth perimeter carrier and protected in normal service.
Heavy leaves sag when ordinary cleanroom hinges are retained.Load-rated hinges and reinforced fixing plates spread the increased door mass into the frame.
Unplanned glazing or access hardware interrupts the intended barrier.Compatible vision panels, closers and latching preparations are incorporated during doorset manufacture.
Typical Applications
Pharmaceutical fire compartmentsBattery manufacturing clean areasLaboratory escape routesHealthcare cleanroom boundariesControlled technical plant access
