Every window and door is made to measure in our UK facility — not pulled from a shelf — so your specification travels intact from quote to installation. We invest in modern fabrication, rigorous QA, and direct relationships with trade partners who demand repeatability on every project.

Manufacturing process
A disciplined four-stage workflow keeps lead times tight without compromising finish or performance.
Design
Every specification is engineered in CAD before we cut a single profile. Thermal, security, and ventilation targets are locked in upfront.
Fabrication
Profiles are cut, welded, and cleaned on our UK lines. Hardware is fitted, glazing is sealed, and each unit is assembled to your exact order.
Quality Control
Dimensional checks, operation cycles, and seal inspection. We document every stage so your trade teams can trust the handover.
Dispatch
Protected loading, tracked delivery, and coordinated installation slots. We align dispatch with your site programme to minimise downtime.
Delivery and lead times
Standard lead times typically range from 3–6 weeks depending on profile colour, glazing specification, and current factory capacity. Bespoke orders or large commercial runs may extend this window — your quote will always confirm a realistic dispatch date.
