Arched windows remain very much in style and continue to shape modern architectural trends. They are being used at multiple scales, from oversized glazing and barrel-vaulted entrances to curved cabinetry and softly contoured interior features, adding softness, character and visual interest to both traditional and contemporary designs. Modern architecture is increasingly moving away from rigid lines towards more fluid, organic forms, and arches play a central role in achieving that aesthetic. Far from a passing trend, they remain a versatile, timeless choice for high-end residential and commercial projects.
Arched windows are more than simply a design feature, they can enhance a home’s appeal and potentially increase its market value. Their distinctive shape adds architectural character and kerb appeal, making properties more attractive to prospective buyers. Installing arched windows during a renovation or replacement project offers both visual impact and a tangible financial benefit, helping a home stand out in the market.
Perfect partners for modern roof solutions
With a growing demand in the market for arched aluminium windows and doors, at Sheerline Bespoke, we provide specialist solutions using some of the most advanced bending machinery for efficiency and quality, combining design excellence with years of expertise to deliver custom aluminium solutions for every trade partner.
Bespoke aluminium arched frames for installers
We manufacture arched aluminium window frames made to measure, supplying fabricators and installers with installation-ready products and reliable lead times that keep projects moving without delays. Every frame is precision-engineered and fabricated entirely in-house at our Derbyshire factory, so we can match the character of traditional properties or the clean sightlines of a contemporary build. You handle the install, we handle the fabrication.
Curved, shaped and arched aluminium frame options
Not every opening is a rectangle, and we build for the ones that are not. Our range includes 10 distinctive styles spanning arches, gothic arches, curves and circles, all made to exacting standards. Each frame is produced on a TIM-ING profile bending machine for consistent precision and repeatability, and you can specify flush, stepped or no sash to suit the design. These frames sit alongside our wider aluminium roof systems when a project calls for shaped glazing throughout.
Where arched aluminium windows are used
Arched aluminium frames are designed for projects with character and purpose. They suit older and heritage properties as readily as contemporary new builds, thanks to flexible design options and clean, consistent sightlines. Engineered for energy efficiency, they help reduce heat loss while maximising natural daylight, which makes them equally at home in feature gables, period replacement openings and statement architectural glazing.
Trade supply, fabrication and project support
We are your go-to trade aluminium partner, supplying fabricators, installers, architects and self builders rather than selling direct. Our experienced team is on hand to help with product selection and any technical support you need before a job goes into production. Because everything is fabricated in-house, we control quality and lead times and supply frames ready for installation. For projects combining shaped glazing with overhead glazing, we also produce a matching aluminium rooflight. Full technical downloads are available for specification.
Arched frames for heritage, modern and commercial projects
Our arched frames are ideal for both heritage and modern applications. On older properties, the flexible design options let us suit existing architectural character, while on contemporary builds the slim aluminium sightlines let the glazing take centre stage. Manufactured from high-grade aluminium for structural integrity and long-term performance, and available in a wide range of colours including dual shades and woodgrain foils, they give your clients full customisation. The same frames complement our S2 conservatory roof and S1 roof lantern where a project combines vertical and overhead glazing.
