Commercial triple glazing — shopfront, office, hospitality & education spec
Triple-glazed sealed units built to commercial spec — oversized panels, trade lead times, and full BS-EN documentation pack on every order. Pane Relief supplies TG units to glaziers, shopfitters, M&E contractors, and main contractors working on offices, retail units, hospitality fit-outs, schools, healthcare estates, and listed-building consents that demand both thermal and acoustic performance. Stock-spec 44mm and 52mm triple-glazed configurations (4-12-4-12-4 argon or krypton, soft-coat low-E on two surfaces) hit U-values from 0.6 W/m²K — well inside Part L 2026 and Future Homes Standard for non-domestic.
Architects, M&E consultants, building control
U-values from 0.6 W/m²K, g-values from 0.30, Rw to 41dB on laminated triple builds. We issue Declaration of Performance (BS EN 1279), Performance Data Sheets, BIM-ready glass schedules, and CWCT shopfront test data on request.

Six common commercial TG scenarios. Pick the closest match — each links to the relevant flagship product or filtered range.
Shopfront / curtain wall
Toughened TG to BS EN 12150 + CWCT impact & weatherability standards. Oversized panels to 3200×1800mm stock.
Office partitions & facades
Acoustic-laminated TG up to Rw 41dB. Solar-control low-E for south-facing facade glare control (g-value 0.30-0.40).
Hospitality / restaurant
Toughened or laminated safety TG for bar fronts, conservatory restaurants, hotel curtain wall. Privacy or obscure options.
Schools / healthcare
Laminated TG meets impact-protection requirements. BB 100 fire compliance and Approved Doc K complied with via laminated PVB / SGP interlayers.
Fire-rated overlap
BS 476 Pt22 EI30 / EI60 builds available on enquiry. Pilkington Pyrostop / Pyrodur and Schott Pyran integrated in TG sandwich.
Bespoke / oversized
Anything >3200mm or non-rectangular — send drawing or DWG. 10–14 working day lead time on commercial triple spec.
Spec, source, and site-deliver — how we work with contractors
Commercial orders rarely fit a stock-spec dropdown. Here's how a typical contractor quote flows.
5-stage commercial workflow
- Send the glass schedule (PDF, Excel, or DWG) to sales@panerelief.co.uk — we'll quote within 24 hours with U-value, g-value, Rw, and Pa wind-load figures.
- Approve the spec, sign the trade account application, or pay pro-forma if preferred.
- We supply to your programme — typical lead time 10–14 working days for commercial triple spec.
- Pre-delivery photos and unit-by-unit kitemark / CE / UKCA stamp record sent before dispatch.
- Booked site delivery on stillage, hiab if required, with banksman support to ground level. POD signed on-site.
Pricing & documentation
Commercial pricing is quote-based, not list-priced — too many spec variables (interlayer, coating combination, krypton vs argon, edge-spacer type, kitemark, fire-rating). The "from" prices on product pages reflect our smallest stock-spec equivalent for benchmarking only.
Every order ships with: Declaration of Performance (BS EN 1279-5), UKCA / CE mark certificate, U-value & g-value test data, and on request: BIM-ready glass schedule, CWCT shopfront compliance, BS 476 fire-rating evidence.
Commercial triple glazing — FAQ for specifiers
Q: Do you supply to BS / CWCT shopfront standards?
Yes. Toughened triple-glazed shopfront units comply with BS EN 12150 (toughened safety glass), BS EN 1279 (sealed unit durability), and where used in CWCT-tested shopfront systems (e.g. Schueco FW50+, Reynaers CW86, Kawneer 1202) we supply matching unit spec and Performance Data Sheets. We can provide third-party CWCT TN66 / TN67 weatherability and impact-test evidence on request for the unit build (not the framing system).
Q: Can you do fire-rated triple glazing (BS 476 Pt 22)?
Yes — on enquiry. Fire-rated triple glazing is a hybrid build: the fire-protective pane (Pilkington Pyrostop, Pyrodur, Schott Pyran or Vetrotech Contraflam) is integrated as one or more of the three panes in a TG sandwich, retaining EI30, EI60, or E120 integrity-only ratings. Always quote the framing system you're glazing into — fire-rating is a glass + frame + intumescent gasket assembly, not a glass-only certification.
Q: What's the max size for an oversized commercial TG panel?
Stock-spec to 3200×1800mm in standard production. Beyond that we use jumbo-plate manufacturers — anything up to 6000×3210mm on enquiry. Weight rises rapidly: a 3000×1500mm TG unit at 12-12mm spacer is around 230kg, so factor in stillage delivery, hiab unload, and frame structural capacity.
Q: What U-value can you hit?
Stock TG spec at 44mm or 52mm with argon fill, two soft-coat low-E surfaces, and warm-edge spacer hits U-value 0.6-0.8 W/m²K (centre-pane). Krypton fill drops that further to ~0.5 W/m²K on a 52mm 4-16-4-16-4 build. Whole-window U-value will be higher (typically +0.3-0.5) depending on the frame's thermal break performance. We can model the centre-pane U-value for your specific build on request.
Q: Acoustic performance — what dB ratings can you reach?
Standard 44mm TG hits around Rw 35-37dB. Stepping the outer pane to 6.4mm or 6.8mm laminated acoustic glass (Pilkington Optiphon or Saint-Gobain Stadip Silence) lifts that to Rw 39-41dB. For Building Bulletin 93 classroom acoustics or BS 8233 residential-near-busy-road compliance, we'll quote a laminated TG build matched to the target dB(A) reduction.
Q: Do you supply BIM models / CAD blocks for design coordination?
For standard sealed-unit builds, no — the unit is too thin and geometrically simple to warrant a Revit family. We supply the glass schedule in your preferred format (Excel, CSV, PDF) and unit-level performance data (U-value, g-value, Rw, light transmittance, reflectance) that your facade modeller can pull into the building energy model and IES / DesignBuilder simulation.
Q: What insurance / compliance documentation can you provide?
Public liability £10M, products liability £5M, employers' liability £10M. We're CHAS-accredited, registered on Constructionline Gold, and SSIP-aligned. ISO 9001 quality system in place; ISO 14001 environmental management. Evidence pack issued on request before contract award.
Q: Lead times and delivery for commercial orders?
Stock-spec commercial TG: 10-14 working days. Non-stock spec (acoustic, fire-rated, oversized, krypton): 10–14 working days. Site delivery booked to your slot — we'll work to the principal contractor's logistics plan. Stillage return collected free on the next delivery.
Q: Can you support a design-and-build retrofit on an existing curtain wall?
Yes. Send drawings or photos of the existing curtain wall — we'll specify a like-for-like or upgraded unit spec, quote with breakdown by unit and elevation, and coordinate with your facade replacement programme. Typical retrofit scope is glass-only swap; we don't supply or fit the carrier system, but we work routinely alongside Schueco-, Reynaers-, and Kawneer-trained installation teams.
