Service penetrations leave unfinished gaps around pipes or cables.
Choose sleeves, boots or penetration sealing systems that match service dimensions, substrate thickness and the required separation.
Finish the details that connect the room
Cleanroom Installation Accessories
Bring panels, services and equipment together with installation accessories chosen for the connection. Explore sealants, gaskets, fasteners, penetration seals and finishing components that support cleanable joints and practical maintenance access. Match the accessory to the substrate, movement and operating conditions so small installation details do not become avoidable gaps, damaged edges or difficult-to-service interfaces later.
Connect compatible materialsChoose sealants, gaskets and fixings for the panel surfaces and services they must join.
Address openings and edgesUse appropriate penetration and finishing components where utilities or traffic interrupt the room envelope.
Keep maintenance practicalInclude service access, removable parts and replacement seals when detailing the installation.

Sealants & Repair Compounds
Close joints or repair compatible surfaces using compounds selected for their substrates and exposure. Compare curing, movement and cleaning compatibility; specialized firestop applications require the appropriate complete assembly.

Gaskets & Seals
Maintain suitable sealing contact at doors, windows and equipment joints. Select material, profile and compression according to the mating surfaces, cleaning chemicals and expected operating conditions.
Explore Products
Panel, Ceiling & Fastening Hardware
Secure panels and suspended components with hardware matched to the supporting construction. Confirm connection geometry, load requirements and access before choosing connectors, brackets, rods or anchors.

Penetration Sealing Systems
Detail cable and pipe openings with compatible sleeves, boots and sealing systems. Consider service dimensions, later changes and the separation requirements of the wall or ceiling assembly.

Duct, Fan & Pipe Installation Accessories
Connect and support mechanical services with appropriate gaskets, flexible links and hangers. Match dimensions, load and movement conditions while retaining access for inspection and future maintenance.

HEPA Filter Installation Accessories
Fit and test filter installations using compatible clamps, seals and access ports. Match the housing and filter interface carefully; extra clamping force does not correct an unsuitable seal.

Protection, Access & Finishing Accessories
Finish exposed edges, protect traffic contact points and retain access to services. Choose profiles, guards and panels that fit the room surfaces and remain practical to clean.
Explore ProductsGood cleanroom details continue beyond the main panels
An installed room contains many interfaces: panel joints, door seals, cable openings, pipe sleeves and filter seats. Accessories need to match those interfaces so the finished surfaces can be cleaned and the intended separation maintained.
Material compatibility matters at both installation and later cleaning. A sealant must adhere to the substrate and tolerate the operating environment; a gasket must fit its seating geometry; a fastener must suit the load and supporting construction. Similar-looking parts can have different responsibilities.
STjh offers connection, protection and finishing products for these everyday details. Send joint dimensions, substrate information and the relevant drawings so accessories can be selected as part of the assembly instead of substituted on site by appearance alone.
Solutions for Your Purchasing Challenges
Joint materials crack, detach or deteriorate during cleaning.
Compare movement capability, substrate adhesion and chemical compatibility before selecting sealants and gaskets.
Trolleys damage exposed corners and wall edges.
Add suitable guards, rails or finishing profiles at the actual contact points, with attachment details that remain cleanable.
Filters or ceiling parts are difficult to secure and service.
Select matching clamps, suspension components and access details for the installed system rather than improvised hardware.
Match Products to Your Working Environment
Panel and ceiling installation
Coordinate connectors, suspension hardware and finishing products around the room's supporting construction.
Utility penetrations
Detail pipes and cables where they pass through cleanroom walls, floors or ceilings.
Refurbishment and maintenance
Replace worn seals, protect damaged edges and retain access to installed room services.

Questions Before You Order
Can one silicone sealant be used for every cleanroom joint?
No. Substrate adhesion, movement, chemical exposure and curing conditions vary. Choose the sealant for the joint and verify compatibility with the surfaces and cleaning regime.
Does firestop sealant alone make a penetration fire-rated?
No. Fire performance applies to a suitable tested assembly, including substrate, opening, services and installed sealing details. Select the complete system for the required application.
What information helps identify a replacement gasket?
Provide the cross-section, dimensions, material where known and photographs of the seating arrangement. Compression, cleaning chemicals and temperature are also useful for identifying a compatible option.
