What sets our structural corner windows apart in Hitchin.
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.

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 Hitchin homeowners tell us.
"Slim aluminium sashes in anthracite grey — exactly the balance of period feel and modern lines we wanted. Conservation area approved."
"Punctual, quiet, tidy, honest. Three years on the front door still closes with that satisfying thud, and the paint finish hasn't moved."
"A proper trade. Every promise kept — from the timescale to the finish. We've since recommended them to three neighbours."

We prepare planning-ready drawings with matched sightlines, glazing-bar depths and hardware for Hitchin projects that require them.
- What guarantee covers structural corner windows in Hitchin?

- Can I see recent structural corner windows work near Hitchin?
- Yes — we can share recent structural corner windows case studies from across Hertfordshire, including projects in Ickleford, Great Wymondley and neighbouring towns. Ask your surveyor at the on-site visit.
- What thermal performance does structural corner windows achieve in Hitchin?
- Energy-efficient structural corner windows installed across Hitchin, Hertfordshire 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.
