UK casements built between 1965 and 2025 vary in rebate dimensions by mfr, by year, by frame profile, and even by individual sash within a multi-leaf window. Trying to force every project through a 5-size stock list produces a lot of \"close but not quite\" outcomes and frustrating fitter trim-back work. The made-to-measure flagship is the catalogue surface for the configurator's any-size capability — a browseable entry point that lets buyers see real reference prices, then route into the configurator for their actual aperture.\u003c\/p\u003e\n\n\u003ch2\u003eHow this flagship works\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStock-size variants below\u003c\/strong\u003e are listed at the standard argon-double-glazed price per stock size, calculated at £85\/m² × 1.15 argon uplift, £45 floor — the same math the configurator uses.

Floor is £45 per unit. The configurator's quote = the buy price; no markup at order step. This is the same math used to set the stock-size variant prices on every Pane Relief flagship product.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the minimum size I can order?\u003c\/h3\u003e\n\u003cp\u003e200×200mm. Below this, edge-seal yield drops sharply and the unit becomes uneconomic. For very small specialist sizes (signal-glazing inserts, mirror-fit small panels), contact us directly for a manufacturing-feasibility check.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's the maximum size?\u003c\/h3\u003e\n\u003cp\u003e3000×2500mm in single-pane manufacturing. Above this size, the float-glass plant handling and tempering equipment hits its size cap, and units in this range require oversized handling and freight which we coordinate at order step. For oversize commercial spec, contact the trade desk for a custom quote.\u003c\/p\u003e\n\n\u003ch3\u003eCan I get a quote without ordering?\u003c\/h3\u003e\n\u003cp\u003eYes — the configurator delivers a written quote PDF on completion. Quote is valid for 30 days from generation; pricing locked at the per-m² rate at quote time (we don't surprise-uplift between quote and order).\u003c\/p\u003e\n\n\u003ch3\u003eLead time for configured orders?\u003c\/h3\u003e\n\u003cp\u003e7-10 working days for standard rectangular argon-double spec. Add 3 days for Low-E coating, 3 days for toughening (BS EN 12150), 3-5 days for lamination (BS EN 14449), 5-7 days for shaped (arched, raked, circular), 14-21 days for triple-pane builds, 21-28 days for ultra-slim conservation specs.\u003c\/p\u003e\n\n\u003ch3\u003eCan I configure for a heritage \/ listed-building application?\u003c\/h3\u003e\n\u003cp\u003eYes — the configurator includes slim-cavity, krypton-fill, narrow steel spacer, and reduced-pane-thickness options. For listed-building consent submissions, we recommend the dedicated \u003ca href=\"\/products\/12mm-histoglass-equivalent-slim-conservation-unit\"\u003e12mm Histoglass-Equivalent Slim Conservation Unit\u003c\/a\u003e flagship which carries the conservation-officer documentation flow built in.
