Aluminium glazing
Windows, doors, curtain walling and fire-rated screens are designed and manufactured as part of the wider envelope.

Made in-house
In-house aluminium glazing, sheet metal and bespoke metalwork that strengthens control at the most demanding envelope interfaces.
The division
Project-specific components are produced for the actual site condition rather than adapted during installation. Direct links between design, workshop and site teams improve accuracy, shorten decisions and reduce dependency on third parties.


How it works
Windows, doors, curtain walling and fire-rated screens are designed and manufactured as part of the wider envelope.
Flashings, cassettes, soffits and exact project profiles are formed under documented quality controls.
Project-specific stairs, handrails, walkways, access systems and architectural details resolve non-standard conditions.
