Timber
Timber windows and doors for period-sensitive homes and character properties.

For projects that want dark frame definition, glazing bars and architectural character without taking the full steel route.
Start here when the project wants a Crittall-like frame rhythm, but aluminium is the better route for cost, lead time or performance.

Industrial aluminium works when the frame layout is treated as part of the architecture, not an afterthought applied to a standard aperture.

Internal screens and partitions can divide a space while keeping borrowed light, long views and a more architectural feel.

Handles, interlocks, bars and surrounding finishes need to be specified together so the result feels deliberate rather than decorative.
These details are small on paper, but obvious in daily use.

A defined frame rhythm can add structure to larger garden-facing glazing.

Internal glazing gives separation without losing light or visual connection.

Handles and profile junctions need the same restraint as the frame layout.
Both can be right. The useful distinction is whether the project needs genuine steel heritage or the faster, lighter aluminium route.
| Decision | Industrial aluminium | Genuine Crittall |
|---|---|---|
| Best for | Steel-look briefs with practical constraints | Projects that specifically require genuine Crittall |
| Material | Aluminium with industrial styling | Steel with authentic Crittall profile language |
| Typical driver | Cost, lead time and thermal practicality | Heritage, authenticity and architectural steel character |
| Next step | Confirm survey, bars and finish | Confirm genuine Crittall requirement and available product detail |
