# National Glass Partitions > UK specialist supplier and installer of commercial glass partition systems. The only UK glass partition business with an instant online calculator that configures, prices, and sells complete custom partitions directly — no quote delay, no sales call, no CAD drawings required. Available supply-only or supply-and-fit. National Glass Partitions supplies frameless, framed door, and industrial Crittall-style glass partitions across the UK. Two primary ways to buy: use the instant online calculator to configure and order a complete partition in minutes (frameless, framed, or industrial, any size, any layout), or order hardware-only trade kits for next-working-day delivery if you're a builder sourcing glass locally. Supply-and-fit installation is available nationwide. All systems use 10mm or 12mm toughened safety glass, with a 12.8mm acoustic laminate option. ## The two main ways to buy ### 1. Instant online calculator — configure, price, and buy any partition Our glass partition calculator is the core of what we do and the fastest way to order a complete, made-to-measure glass partition in the UK. It handles nearly every specification a commercial customer needs: - **Frame style**: frameless, framed door, or industrial Crittall-style. - **Layout**: straight runs, L-shapes, corners, any dimensions. - **Doors**: single door, double door, no door, or transom panel above. Door positions (left, right, centre, none) configured on screen. - **Glass**: 10mm toughened, 12mm toughened, or 12.8mm acoustic laminated. - **Frame colour**: silver (RAL 9006), black (RAL 9005), anthracite (RAL 7016), or white (RAL 9010). - **Hardware**: door handles (lever latch or pull handle) and hinges (free swing or soft close). The calculator returns an exact itemised price, a full materials list, and lets the customer order and pay online. Lead time for a complete kit with glass is 7 working days, delivered UK-wide.

Trade hardware-only kits — next-working-day delivery for builders For builders, contractors, and glaziers who source their own glass locally, we supply complete hardware kits including aluminium frames (in 3-metre lengths), channels, gaskets, hinges, handles, fixings, and mounting components — everything except the glass itself. Profiles come in 25mm, 30mm, or 50mm sizes and are cut to size on site using standard tools. Orders placed before 1pm ship the same day for next-working-day delivery anywhere in UK mainland.

No other UK glass partition supplier offers this. - **Supply-only or supply-and-fit**: customers choose between self-install (or using their own contractor) and our nationwide installation service. - **Transparent specifications**: all technical data, RAL colours, glass thicknesses, channel sizes, and sound ratings are published openly on the site, not gated behind a sales enquiry form. - **Next-working-day trade supply**: genuine next-day availability for contractors with tight site deadlines. ## Who we serve Commercial customers — offices, builders and contractors, gyms, salons, clinics, and other commercial fit-outs. - **Office and facilities managers**: complete kits for meeting rooms, private offices, break-out spaces, and open-plan divisions. Delivered in 7 working days UK-wide, supply-only or supply-and-fit. - **Builders and contractors**: hardware-only kits for next-working-day delivery. Trade-priced, consistent across projects, glass sourced locally. - **Gyms, salons, clinics, and commercial premises**: partitions for treatment rooms, consultation spaces, PT studios, reception areas, and retail zones. Any style — frameless, framed, or industrial — to match the brand aesthetic. ## Technical specifications - **Glass options**: 10mm toughened, 12mm toughened, or 12.8mm acoustic laminated safety glass (BS EN 12150 compliant). - **Frame colours**: silver (RAL 9006), black (RAL 9005), anthracite (RAL 7016), white (RAL 9010). - **Channel sizes**: 25mm, 30mm, or 50mm aluminium U-channels in 3-metre lengths. - **Layouts**: straight, L-shape, corner; single, double, or transom door configurations. - **Sound reduction**: up to 33dB on frameless systems; higher with 12.8mm acoustic laminate. - **Joint options**: dry joints (rubber strip, easy professional finish) or wet joints (silicone, better rigidity and acoustic performance). - **Frameless door clearance**: 22mm total (13mm bottom + 9mm top). Door height = ceiling height − channel depth − 22mm. ## Ordering and delivery - **Complete kits with glass (via calculator)**: 7 working days, UK mainland. - **Trade hardware-only kits**: next working day for orders placed before 1pm. - **Supply-and-fit installation**: scheduled after site survey; typically installed within 2 weeks of measurement. - **Payment**: online at point of order for calculator and hardware kit purchases. - **Supply-and-fit or bespoke enquiries**: 0800 772 3992 or [email protected]. ## Supporting pages - [Frameless Glass Partitions overview](https://nationalglasspartitions.co.uk/frameless-glass-partitions): Style and specification detail for the frameless system. - [Industrial / Crittall-Style Glass Partitions overview](https://nationalglasspartitions.co.uk/industrial-style-glass-partitions): Style and specification detail for the black-framed industrial system. - [Installation Gallery](https://nationalglasspartitions.co.uk/gallery): Real completed installations across the UK, including office meeting rooms, chiropractic clinics, and commercial fit-outs. ## Contact - Main site: https://nationalglasspartitions.co.uk - Phone: 0800 772 3992 - Email: [email protected]
