Ratings and dimensions below are the manufacturer's published figures; the build-up for a specific opening is confirmed in writing with the quote. ### WH-EXPO — Frameless Glass Partitions & Folding Doors URL: https://weldholm.co.uk/glazing-partitions/wh-expo Glass partitioning that separates and soundproofs a space without closing it off. Structural tempered glass, invisible gaskets, up to 4m — installation quoted separately. WH-EXPO is a glass partition walling system built for internal walls with all-glass doors — dividing and soundproofing a space while keeping sightlines open, unlike a solid wall. WH-EXPO MOBILE extends the same system with high-quality segment doors — accordion and folding configurations — for openings that need to disappear entirely when not in use. Its ability to handle ceiling heights of around 4 m makes it suited to shops, shopping centres, exhibition spaces, and offices that need a genuinely wide, openable divide. Panes are a structural part of both systems, not just infill — and the glazing gaskets stay invisible from either side. Both are available in a range of finishes, and the profile design keeps fabrication and installation straightforward. Specifications: - Tempered glass: 8, 10, or 12 mm - Two profile height options: low (36 mm) and high (100 mm) - Structures up to 4 m high - Invisible glazing gaskets, both sides - Panes are structural, not decorative infill - Compatible with standard architectural door hardware (locks, hinges, suspension brackets, parking systems) - Available in a range of finishes Typical use: Shopfronts, showrooms, exhibition stands, high-ceiling office partitions with wide openable divides. ### WH-80 OFFICE — Acoustic Office Partitions URL: https://weldholm.co.uk/glazing-partitions/wh-80-office Built for offices where sound insulation isn't optional. Up to 50dB noise reduction, built-in cable routing, reconfigurable without a full rebuild. WH-80 OFFICE is a double-glazed internal walling system designed for offices and other public facilities that need genuinely effective sound insulation between spaces. It takes transparent or obscure infill, can incorporate internal louvers, and has room inside the wall for electrical runs and standard power sockets — so a partition doesn't mean giving up outlets or blinds. The system's real strength is versatility: the same construction adapts to reconfigured office layouts without a full rebuild, and on-site execution stays simple even as the floor plan changes around it. Specifications: - Noise reduction up to 50 dB, depending on infill - Infill options: glass panes (4–14 mm), furniture board (16–18 mm), or gypsum plasterboard - Can combine with standard 75 mm gypsum plasterboard - Two wall depth options: 80 mm or 92 mm - Custom space division, angle range 90°–180° - Cables routed inside the wall; standard power socket installation supported - Direct on-site pre-fabrication available - Pairs with WH-45 (centrally-installed or flush) or WH-45 OFFICE doors (centrally-installed leaf, flush-mounted, non-protruding hinges) - Maximum development height: 5.5 m Typical use: Private offices and meeting rooms needing real acoustic separation, reconfigurable open-plan layouts. ### WH-45 / WH-45 OFFICE — Lightweight Glazing & Doors URL: https://weldholm.co.uk/glazing-partitions/wh-45-office A light, solid partition system for spaces that need a clearly marked door. Structural glass leaves, smoke-resistant option, installation quoted separately. WH-45 and WH-45 OFFICE are built for lightweight partition walls that still read as solid — conference rooms and office spaces where the door needs to be unmistakable, not blended into a glass wall. WH-45 OFFICE's tempered glass pane is a structural element of the door itself, not just glazing inside a frame, and the system fabricates both fixed partition walls and all-glass leaves for hinged or swing-type doors. WH-45 on its own extends further — partition walls, windows, manual and automatic sliding doors, swing doors, and vestibules all come from the same profile family. Where smoke control matters, the system has a dedicated smoke-resistant configuration. Specifications: - Design depth: 45 mm - Infill range: 2–25 mm, with dedicated 8, 10, and 12 mm tempered glass options - Continuously mounted glazing gaskets — no corner cutting required - All-glass door leaves for hinged and swing-type doors - Smoke-resistant configuration available (WH-45D, classes Sm and Sa) - Compatible with standard architectural hardware - Applications: partition walls, windows, doors (manual & automatic sliding, swing, vestibules) Typical use: Conference rooms, private offices with a clearly defined entrance, smoke-control zones. ### WH-78EI — Fire-Rated Glazed Walls URL: https://weldholm.co.uk/glazing-partitions/wh-78ei Full fire resistance, without the visible frame between panes. EI30/EI60-rated, 4mm silicone joints, no limit on overall wall length, installation quoted separately. WH-78EI is a silicone-joined glazed wall system built to remove the visible vertical profiles that normally separate glass modules in a partition — while preserving full fire resistance. The joint between panes is just 4 mm, filled with firestop intumescent material and non-flammable silicone, available in black, grey, or white to match the fit-out. Because the wall reads as continuous glass rather than a series of framed panels, spaces fabricated with WH-78EI feel optically larger — while still doing the job a fire-rated partition needs to do: holding a fire zone and keeping evacuation routes viable. Specifications: - Fire resistance classes: EI30 and EI60 - Joint width between modules: 4 mm - Maximum module width: 1.5 m (height up to 3.6 m) or 1.8 m (height up to 3.0 m) - No limit on overall wall length (tested under a "free-edge" model) - Concealed wall mounting - Silicone joint colour options: black, grey, white Typical use: Fire-zone separation in office buildings where an uninterrupted glass sightline matters — reception areas, corridors, open-plan floors needing compartmentation without feeling closed-in. ## Windows, folding & sliding doors, facades URL: https://weldholm.co.uk/windows-doors ### Aluminium Windows (WINDOWS) Thermally broken aluminium window units, fabricated and finished in the same workshop as the partition systems. The same profile discipline that goes into the partition systems applies to window units: structural glazing, concealed gaskets, and hardware that suits the opening rather than whatever the catalogue defaults to. Units are specified per opening, so a fixed light, a top-hung vent, and a tilt-and-turn leaf can sit in the same run without a change of supplier. Finishes follow the same range as the glazing systems, so window frames, partition profiles, and fabricated fit-out elements can all be matched across one project. Exact glazing build-up, thermal figures, and hardware selection are confirmed in writing with your quote — we don't publish a spec that hasn't been set for your opening. Capabilities: - Fixed lights, top-hung vents, tilt-and-turn leaves - Thermally broken profiles - Concealed glazing gaskets - Matched finishes across windows, partitions and fit-out - Hardware specified per opening ### Folding Doors (FOLDING) Multi-leaf folding door runs for openings that need to disappear entirely when they're not in use. Folding runs extend the same logic as WH-EXPO MOBILE: an opening that reads as a wall when closed and vanishes when stacked. Leaves run on a top track, park to one or both sides, and are specified around the opening width, the stack space available, and how often the run gets moved. Hospitality is where these earn their keep — a terrace that opens fully in summer and closes tight in winter — but the same runs suit garden elevations, showroom fronts, and any divide that has to change through the day. Track type, leaf count, and threshold detail are set per opening and confirmed with your quote. Capabilities: - Multi-leaf folding configurations - Top-track running, single- or two-side stacking - Threshold detail specified per opening - Suited to terraces, garden elevations and showroom fronts - Same finish range as the glazing systems ### Sliding Doors (SLIDING) Large-pane sliding runs that park behind a fixed light instead of stacking, for openings where the sightline matters more than a full clear span. Where a folding run trades sightline for a fully clear opening, a sliding run does the opposite: the leaves stay in plane and slide behind the fixed panes, so the closed elevation reads as a near-uninterrupted sheet of glass with one slim meeting stile. Nothing swings into the room and nothing needs stack space at the jamb, which suits living spaces and garden elevations where the opening sits tight against a wall or a corner. Leaf count, which panes move, and the direction they run are set from the opening; the threshold gets detailed around the floor build-up either side, so a flush interior finish and an external drainage channel can be resolved in the same profile. Glazing build-up, running gear and hardware are confirmed in writing with your quote. Capabilities: - Large-pane sliding runs, leaves parking behind fixed lights - Slim meeting stile, in-plane closed elevation - No stack space needed at the jamb - Threshold detailed around the floor build-up either side - Flush pull handles and concealed running gear ### Facades & curtain walling The same profile family scales up to external elevations: curtain walling, shopfront glazing, and glazed entrance bays, fabricated and finished through our production partner and installed by our own team. Send the elevation drawings and we'll tell you plainly what we fabricate in-house, what needs a specialist sub-package, and what it costs — confirmed in writing before anything is ordered. ## Applications by sector URL: https://weldholm.co.uk/applications ### Offices Reconfigurable, acoustically genuine office partitioning. All four glazing systems are specified for office environments, from IT, fintech, and professional-services floors to coworking spaces, covering everything from wide, openable divides to fully fire-rated corridor walls. A typical office run mixes them: single-glazed screens to define open-plan space, acoustic build-ups around meeting rooms and quiet booths, and rated screens where the layout crosses a fire compartment line. Systems specified for this sector: WH-80 OFFICE (https://weldholm.co.uk/glazing-partitions/wh-80-office), WH-45 / WH-45 OFFICE (https://weldholm.co.uk/glazing-partitions/wh-45-office), WH-78EI (https://weldholm.co.uk/glazing-partitions/wh-78ei), WH-EXPO (https://weldholm.co.uk/glazing-partitions/wh-expo). ### Government & Public Sector The same specifier-grade systems, built for public-sector fit-outs. WH-78EI's fire-rated compartmentation and WH-80 OFFICE's acoustic separation suit municipal offices, civic buildings, and other public-sector fit-outs where certification and documentation matter as much as the finish. Get in touch to discuss accreditation and compliance requirements for your specific procurement route, and we'll confirm the documentation that comes with each system in writing. Systems specified for this sector: WH-78EI (https://weldholm.co.uk/glazing-partitions/wh-78ei), WH-80 OFFICE (https://weldholm.co.uk/glazing-partitions/wh-80-office). ### Healthcare & Education Acoustic and fire-rated separation for schools, clinics, and campuses. WH-80 OFFICE's acoustic ratings suit classrooms, consulting rooms, and study spaces; WH-78EI's fire rating suits compartmentation in schools and healthcare buildings. Same systems, same certification, specified for environments where sound and fire performance are non-negotiable. Systems specified for this sector: WH-80 OFFICE (https://weldholm.co.uk/glazing-partitions/wh-80-office), WH-78EI (https://weldholm.co.uk/glazing-partitions/wh-78ei). ### Shopping Centres & Retail Wide, openable divides for portfolio-scale retail fit-outs. WH-EXPO's spec is built directly for shops and shopping centres: a genuinely wide, openable divide suited to a recurring portfolio refit cycle. Paired with retail fit-out fittings from our fabrication workshop for a single-supplier fit-out. Systems specified for this sector: WH-EXPO (https://weldholm.co.uk/glazing-partitions/wh-expo). Bespoke fabrication also applies here: https://weldholm.co.uk/bespoke-fabrication ### Hospitality Sightlines for private dining, acoustics for the back of house. WH-EXPO suits VIP and private dining sightlines; WH-80 OFFICE handles back-of-house acoustic separation. Paired with bespoke furniture and fittings from our fabrication workshop, so the glazing and the pieces around it come from one supplier on one timeline. Systems specified for this sector: WH-EXPO (https://weldholm.co.uk/glazing-partitions/wh-expo), WH-80 OFFICE (https://weldholm.co.uk/glazing-partitions/wh-80-office). Bespoke fabrication also applies here: https://weldholm.co.uk/bespoke-fabrication ### Retail & Shopfronts Shopfronts and showrooms, specified in the system itself. WH-EXPO names shopfronts and showrooms directly in its spec, fitting rooms and stockroom separation included. Combine with retail fit-out fittings from the same workshop. Systems specified for this sector: WH-EXPO (https://weldholm.co.uk/glazing-partitions/wh-expo). Bespoke fabrication also applies here: https://weldholm.co.uk/bespoke-fabrication ### Exhibition Spaces Stands that fold away entirely when the show ends. WH-EXPO MOBILE's accordion and folding configuration is built for exhibition stands: an opening that needs to disappear entirely when not in use, not just a door that closes. Systems specified for this sector: WH-EXPO / WH-EXPO MOBILE (https://weldholm.co.uk/glazing-partitions/wh-expo). ### Private Homes The same systems, specified for residential use. WH-45/OFFICE, WH-80 OFFICE, and WH-EXPO extend to private residential specification on the same commercial terms as everything else on this site: a request for consultation, not an instant quote or a separate residential offer. Systems specified for this sector: WH-45 / WH-45 OFFICE (https://weldholm.co.uk/glazing-partitions/wh-45-office), WH-80 OFFICE (https://weldholm.co.uk/glazing-partitions/wh-80-office), WH-EXPO (https://weldholm.co.uk/glazing-partitions/wh-expo). ## Bespoke fabrication URL: https://weldholm.co.uk/bespoke-fabrication Metal and wood fabrication built in our own workshop in Latvia and installed on site: hospitality furniture, architect-specified one-off pieces, and retail fit-out fittings. Fabrication is quoted alongside glazing so one team is responsible for the whole element. ## How buying works Send drawings, an opening schedule, or simply the sizes and the sound or fire performance you need. You get a written quote that names the system, the glass build-up, the finish and the hardware, with installation priced separately. There is no distributor markup and no gatekeeping on price. Manufacturer warranty duration is not published on the site; exact terms are confirmed in writing with the quote. ## Systems gallery URL: https://weldholm.co.uk/systems-gallery Photographs of installed work, grouped into glass partitions, windows, and doors. Captions describe framing, finish, glazing and opening type only — client names and project attributions are deliberately not published. ## FAQ URL: https://weldholm.co.uk/faq ### What does an EI30 or EI60 fire rating actually mean? EI ratings describe how long a glazed element holds back fire in a real test. E is integrity — the glass and frame stay intact and stop flame and smoke passing through. I is insulation — the unexposed side stays below a temperature that would ignite anything nearby. The number is minutes: EI30 holds for 30 minutes, EI60 for 60. Our WH-78EI system is built for both classes, with a 4 mm silicone joint between panes instead of a visible frame, so the fire-rated wall reads as continuous glass rather than a series of framed panels. ### What's a good acoustic rating for an office partition? Sound reduction is measured in decibels (dB): the higher the number, the more noise is blocked between spaces. A standard internal partition might block 30-35 dB, enough to reduce a conversation to a murmur. For a meeting room or private office where confidentiality actually matters, you want closer to 45-50 dB, which stops speech from being intelligible next door. Our WH-80 OFFICE system reaches up to 50 dB, depending on the infill chosen, and is built specifically for offices and public buildings where sound insulation isn't optional. ### Does a UK glass office partition need CE marking? CE marking confirms a construction product has been tested and declared against the relevant EU/UK standard for its intended use — for glazed partitions, that covers structural performance and, where applicable, fire and acoustic classification. It's not a legal requirement for every internal fit-out, but a specifier who asks for it is checking that what's fitted matches what's on the spec sheet. Every Weldholm system carries CE marking. ### What's the difference between WH-45 and WH-45 OFFICE? WH-45 is the broader profile family: partition walls, windows, manual and automatic sliding doors, swing doors, and vestibules, all from the same 45 mm-depth system. WH-45 OFFICE is the specific configuration built for fixed partition walls and all-glass hinged or swing doors, where the tempered glass pane is a structural part of the door itself rather than just glazing inside a frame. If you need a door that reads as solid glass rather than a framed panel, that's WH-45 OFFICE; if you need the wider range (windows, sliding doors, vestibules), that's WH-45. ### How is Weldholm's £/m² price built — what's included? Every published rate covers the aluminium-framed or fire/acoustic-rated glazing system itself, CE-marked — materials and fabrication only. Installation is quoted separately once we've seen your floor plan and site access, and confirmed in the same written quote. There are two bands because there are two build-ups: Signature for standard aluminium-framed glazed partitions, and Acoustic Premium for the acoustic-rated build-up behind up to 50 dB sound reduction. A floor plan that mixes systems, or a run with non-standard sizes, doors or finishes, gets a full written quote once we've seen the brief. The price we quote is the price you pay: no hidden extras added once the brief is agreed. ### Does Weldholm only supply glazing systems, or also bespoke fit-out furniture? Both, from the same workshop. Alongside the glazing systems on this site, we build the bespoke metal and wood fabrication that goes around them: hospitality furniture, architecture and design collaborations, and retail fit-out fittings, using the same metalworking, laser cutting, CNC milling, powder coating, and carpentry capability. One workshop, one relationship, rather than a separate supplier for the glazing and the fit-out around it. ### What kind of custom metalwork does the fabrication workshop handle? Metalworking, sheet metal and tube laser cutting, metal bending, CNC milling, and powder coating — the same capability set behind our glazing systems, applied to bespoke pieces. Carpentry and woodworking run alongside it for combined metal-and-wood work. ### Can you build bespoke hospitality furniture for a bar, café, or restaurant fit-out? Yes. Bar, café, and restaurant furniture built to the same brief as the space around it — aesthetic, functional, and practical in equal measure, from the same workshop that fabricates the glazing. ### Do you fabricate from an architect's or designer's own drawings? Yes. We build to an architect's or designer's specification directly, adapting materials and construction project by project rather than working from a fixed catalogue. ### Can you handle full retail fit-out fittings, not just furniture? Yes — full-cycle production from drawing to finished shop furniture, fittings, and interior elements, not just standalone pieces. ### Can Weldholm combine a glazing system with matching custom metal fittings in the same project? Yes, and that's the point of having both under one roof — one brief, one point of contact, for the glazed partitions and any custom metal or wood elements the same space needs, instead of coordinating two separate suppliers. ### What materials can the fabrication workshop actually work with? Metal and wood, separately or combined in the same piece — from structural aluminium framing to bar counters, retail fittings, and architect-specified furniture. ## Contact URL: https://weldholm.co.uk/contact Two routes: a consultation request for a full brief, or a quick question.
