What sets our structural corner windows apart in Hampstead.
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.
Structural-Glass Engineering
Engineered as a load-carrying assembly with a hidden steel or aluminium moment post — supports the head detail above without a visible column.
Kitchen Return Favourite
The signature detail of a modern rear extension — a corner window at the sink or breakfast bar turns the whole side elevation into glass.
Fixed or Openable
Standard configuration is two fixed panes. Openable side lights can be added away from the corner where ventilation is needed.
Any RAL Powder Coat
Matched to the surrounding aluminium windows, sliders and doors — single or dual colour, Qualicoat Class 2.
Coordinated Delivery
Site-surveyed, factory-glazed and lifted into position as a single assembly — no on-site glazing at the corner joint.

- What thermal performance does structural corner windows achieve in Hampstead?

- 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.
