Shaped Triple Glazed Unit — Period Homes & Arched WindowsVictorian fanlights, Edwardian arched tops, Gothic arch windows — period properties have glazing shapes that standard rectangular units can't match. Our Shaped Triple Glazed Units are CNC-cut to any profile, delivering modern triple-glazed performance in frames that were designed for single panes over a century ago.We work from templates (card, paper, or digital DXF files) to replicate the exact profile of your existing glazing. Whether it's a semi-circular fanlight, a pointed Gothic arch, or a curved-top sash, our CNC cutting equipment reproduces the shape with millimetre precision.Any Shape, Full PerformanceOur CNC glass cutting equipment handles virtually any shape with clean, accurate edges. The triple-glazed build-up is identical to our rectangular units — three panes of precision-cut glass with Low-E coatings, argon gas fill, and warm-edge spacer bars, delivering the same U-value performance. Shapes: Arches, semi-circles, circles, triangles, trapezoids, Gothic arches, octagons, ovals, and custom profiles Maximum diameter/width: ~2000mm Templates: Card, paper, or digital DXF accepted U-value: Equivalent to rectangular unit of same build-up Glass options: Toughened, laminated, Low-E, obscure Manufactured to BS EN 1279 at our Bristol facility.
