No Visible Corner Mullion
Two fixed panes are silicone-bonded at 90° with a structural corner post inside the frame — from outside, the glass simply turns the corner.

- What thermal performance does structural corner windows achieve in Kettering?
- Energy-efficient structural corner windows installed across Kettering, Northamptonshire achieve whole-window U-values of 0.9–1.4 W/m²K, with the exact frame and glazing specification confirmed after survey.
- Do I need an engineer for a corner window?
- Yes — the corner needs a structural design because it carries load from above without a visible column. We coordinate with your project engineer and provide the CAD detail, or we can supply structural calculations ourselves via our engineering partner.
- Can the corner be an opening window?
- The corner itself is always fixed — the structural silicone bond can't take a hinged sash. Openable side lights can be positioned away from the corner if ventilation is needed.
- How is it installed?
- The two panes are glazed into the frame in the factory and delivered as a single assembly. On site, we lift it into position (usually with a Hiab crane) and seal it to the surrounding brickwork or cladding.
