Sealwise WCB is waterproof, antibacterial clinical furniture substrate. NHS laboratory tested against MRSA, E. coli, and K. pneumoniae. 0% water absorption. Specified in NHS Trusts nationwide.
The Problem
MDF and MR MDF absorb moisture. In clinical environments — where aggressive cleaning is constant and infection control is critical — this absorption leads to swelling, delamination, and structural failure. Worse, moisture creates harbourage points for bacteria between the substrate and laminate face.
Replacement cycles are expensive and disruptive. Ward closures during refurbishment cost NHS Trusts bed capacity. And every replacement is another procurement cycle, another installation disruption, another capital expenditure.
The Choice
NHS Laboratory Tested
WCB was tested by a leading NHS microbiology laboratory using BS EN 16615:2015 (the four-field test). The board was contaminated with organic soiling, inoculated with pathogenic bacteria, and cleaned with a single microfibre wipe and tap water.
The result: MRSA, E. coli, and K. pneumoniae were all reduced to below detection limits — regardless of soiling. The board’s integrated silver-based antibacterial protection continues working between cleaning cycles.

How It Works
We work with your procurement team to understand requirements. Specify Sealwise WCB as the substrate for clinical cabinetry, worktops, and furniture. Full technical data and test certificates provided.
Your furniture manufacturer processes WCB exactly like MDF. Same tools, same fixings, same techniques. W14 chemical welding creates sealed edges. No specialist training required.
Install once. The furniture performs continuously in wet clinical environments without swelling, delamination, or moisture damage. Lifetime waterproof guarantee included.
Why WCB Works
Sealwise WCB combined with the W14 chemical welding system creates clinical furniture with no water entry points, built-in antibacterial protection, and chemical resistance to hospital-grade disinfectants.
WCB is a closed-cell polymer board. There are no internal pathways for water to enter — not through the face, not through cut edges, not through fixings. It physically cannot absorb water at any depth or duration.
Silver-based antibacterial protection is integrated into the board itself. Not a coating. Won't wear off with cleaning. Works 24/7 between cleaning cycles to reduce bacterial populations.
Withstands hospital-grade disinfectants including chlorine-based solutions, hydrogen peroxide, and quaternary ammonium compounds — without surface degradation or loss of antibacterial properties.
The W14 chemical welding system permanently fuses panels together, creating homogenous edges with no gaps where bacteria can harbour. No silicone. No mechanical fixings failing over time.
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
WCB costs more per sheet than MDF. But clinical furniture built with WCB doesn’t need replacing. Over a 25-year building lifecycle, the savings compound significantly.

WCB isn’t just for healthcare — it’s the same closed-cell technology trusted in veterinary facilities, dental surgeries, cleanrooms, and flood-resilient kitchens across the UK. Paired with our W14 chemical welding system, it creates permanently sealed joints that are impossible to penetrate. Same product, same lifetime guarantee.
