GW70 Shaped Windows — Glazing for Bespoke Designs
Architectural glazing often calls for more than just square or rectangular shapes. The GW70 Shaped Window meets this need with clean detailing, high thermal performance, and tailored designs to suit complex rooflines or elevation features.
Whether used for gables, vaulted ceilings, or shaped corner glazing, it allows for creative expression without compromise on insulation or strength.
Every shaped unit is manufactured to order, ensuring a precise fit and consistent sightlines across the project. From traditional properties with curved windows to bold modern designs with sharp angles or geometric layouts, GW70 Shaped Windows allow natural light to become a key architectural feature.
Precision Manufacturing from Glideline
All GW70 Shaped Windows are fabricated in-house at Glideline, using high-grade insulated aluminium and the same profile system as our standard GW70 casement or GT70 tilt and turn range. This ensures consistent aesthetics and performance across every elevation and where our shaped windows meet other window, bifolds or sliding doors. Each shape is CNC-cut and finished with the flawless quality and attention to detail, checked at every stage of manufacturing.
Because no two shaped windows are the same, we work closely with architects, designers, and installers to understand each requirement. The result is a window that performs reliably, looks sharp, and integrates cleanly with other glazed elements on your project.
Technical Support for Unique Projects
Shaped windows often demand detailed design planning, accurate sizing, and site and structural opening coordination. Glideline supports your project with full technical guidance, drawings, and responsive service throughout the specification and ordering process.
With flexible glazing options, premium finishes, and short lead times, we help ensure that even the most complex shaped glazing requirements are met efficiently. The GW70 Shaped Window is a dependable, high-quality solution for adding architectural character and natural light to any project.

Reviews
Thank you to the installers Joe and Luke for their hard work. It wasn't easy going up all the stairs but they were happy doing so and I couldn't be happier with the doors. Also Henry has been fantastic from start
Glideline installed 6 sets of sliding doors in our house. This was a major investment for us so we wanted it to be just right. David and all the team were friendly and helpful from start to finish. Henry was great.
