Specify it once, it arrives right.
The risk in a door specification is not the door. It is the three components, three suppliers and one carpenter standing between your drawing and what gets built — and when it does not line up, it is your detail that gets questioned. We supply all three as one product, matched in the works.
Everything you need to write the specification.
Technical data sheets
Construction, core, tolerances and hardware preparation, per range.
Construction & jamb details
Plan, section, jamb and threshold drawings in DWG, DXF and PDF.
The finish library
Veneer, laminate, paint and steel surface finishes across every range.
Standard sizes
The dimensional envelope for the wooden and steel ranges.
Installation & tolerance guidance
Clearances, fixing detail and gasket specification.
Specification text
A clause per range, ready to paste into a document.
Opening sizes at masonry stage
The last responsible moment to change a door specification.
Once shuttering is struck, a door that does not fit becomes a chased wall or a compromised detail. This sheet gives opening dimensions for both ranges, in the form you need at masonry stage.
Steel range, published
- Heights
- 2050–2350 mm
- Widths
- 860–1170 mm
- Configurations
- Single · unequal pair
An unequal pair — a primary leaf for daily use, a secondary opened for access.
Identical across all four finishes.
| Shutter thickness | 32–60 mm |
|---|---|
| Shutter width | 600–1200 mm |
| Shutter height | up to 3000 mm |
| Frame thickness | 40–60 mm |
| Frame width | 100–300 mm |
| Architrave thickness | 8–18 mm |
| Architrave width | 30–70 mm |
| Architrave profile | L-profile or Flat profile |
| Frame timber | Beech, Meranti or Teak Pine |
What can be varied.
Most of what specifiers assume is bespoke is inside the standard range. Raise the non-standard request — do not design around it.
- Bespoke colour matching on the Skin range
- Shutter heights to 3000 mm
- Shutter widths to 1200 mm
- Frame widths to 300 mm
- L-profile or flat architraves
- Veneer-wrapped frames for deliberate contrast
Physical samples
Swatches to your practice address.
Finish swatches plus an edge or section sample, so you can see how the banding is handled rather than take our word for it.
Request SamplesCPD & studio visits
A session on engineered door systems.
A lunch-and-learn at your studio, or a visit to the works — on engineered construction, installation tolerances, and where door specifications actually go wrong. Ask and we will arrange it.
Arrange a sessionYour technical contact
One person, from specification through to delivery.
Call either published number and ask for technical. You will be given a named contact who stays with the project from specification through to delivery.

Specifying Doorzzen on a live project?
Tell us the project and the stage and we will send the documents you actually need — not a brochure. Select “Architect / Specifier” and it reaches the technical queue directly.
