Sealwise WCB is the waterproof, antibacterial sheet material for cleanroom wall panels, furniture, and pass-throughs. Won’t shed particles. Won’t absorb moisture. Won’t degrade under your cleaning protocol. Guaranteed for life.
The Problem
Cleanrooms exist to control contamination. Every surface, every joint, every panel is a potential source of particles, moisture ingress, or microbial harbourage. The two materials most commonly used — compact laminate and stainless steel — both get the job done. But neither is perfect.
Compact laminate is affordable but can’t be sealed at the joints. Stainless steel can be welded but it’s expensive and heavy. Until now, there wasn’t a material that’s lightweight, easy to fabricate, chemically sealed at every joint, and affordable.
The Choice
Three Demands. One Material.
The closed-cell PVC core doesn't shed fibres or particles. W14 chemical welding eliminates the silicone joints that degrade in compact laminate — creating truly sealed surfaces.
0% water absorption under BS EN 317. Wet wipe-downs, fumigation, and humidity won't affect the substrate. The board physically cannot absorb moisture.
Withstands IPA, hydrogen peroxide, sporicidal agents, chlorine-based cleaners, and fumigation chemicals. Your protocol won't degrade the material.
How It Works
We'll send WCB samples with full technical data within 24 hours. Test it against your cleaning protocol — IPA, sporicidal agents, fumigation exposure.
Give the samples to your cleanroom builder or furniture manufacturer. WCB machines with standard woodworking tools — no specialist equipment required.
W14 sealed panels and furniture perform continuously without degradation. Lifetime waterproof guarantee. No revalidation from material failure.
Why WCB Works
Sealwise WCB combined with the W14 chemical welding system delivers cleanroom panels and furniture with zero water absorption, integrated antibacterial protection, full chemical resistance, and permanently sealed joints.
WCB is a closed-cell polymer board. The core cannot absorb moisture from wipe-downs, fumigation, or humidity — protecting the substrate and the controlled environment it sits in.
Silver-based antibacterial protection is integrated into the board. Not a coating. Working continuously between cleaning cycles to reduce microbial contamination on surfaces.
Withstands IPA, hydrogen peroxide, sporicidal agents, and all standard cleanroom decontamination chemicals without surface degradation — cycle after cycle.
The W14 chemical welding system permanently fuses panels into homogenous surfaces — something compact laminate physically can't achieve. No silicone. No mechanical fixings.
Applications
The largest surface area in any cleanroom. WCB panels with W14 welded joints create continuous, sealed surfaces with no gaps for particles or moisture to penetrate.
Workbenches, storage cabinets, and shelving that face the same cleaning protocols as the room itself. WCB furniture won’t swell, shed, or harbour contamination.
Transfer stations between classified and non-classified zones are critical control points. WCB’s sealed construction maintains the barrier between environments.
Benches, lockers, and step-over barriers in gowning areas face constant contact and frequent cleaning. WCB provides durable, hygienic surfaces in the transition zone.
Total Cost of Ownership
When cleanroom surfaces degrade, you don’t just replace a panel. You revalidate the room. That means testing, documentation, potential production downtime, and the risk of non-compliance. WCB removes that cycle entirely.
Proof, Not Promises
"WCB gives cleanroom builders a substrate that handles the three things that matter most: it doesn't shed, it doesn't absorb, and it doesn't degrade under cleaning.
