Some doors just need to do the job
Not every door needs to be the most beautiful thing in the room. Some doors need to do a job — reliably, durably, and without fuss — for the lifetime of the building they’re installed in.
The Sentinel is that door. Built on the Jansen Economy 50 profile, it combines certified fire resistance from E30 to E120 with acoustic insulation up to 44dB, Class 4 air permeability and Class 8A water tightness. It works internally and externally, across residential, commercial and public building applications, and handles everything from standard single doors to arched configurations and smoke-control specifications.
The 105mm face width keeps it clean and considered rather than heavy — steel that reads as architectural rather than industrial. And because every door is manufactured to order, it can be finished in raw steel, galvanised steel or stainless steel, with the full RAL palette available in powder-coat or wet paint.
Practical, certified and built to last. Sometimes that’s exactly what a project needs.
Internal door collections
Three families.
Every door type.
Internal – original profile
Internal steel doors & partitions
Twenty millimetres of steel frame. Everything else is glass, light and space. The Foundry is our original slim internal profile — hand-welded, precisely crafted, and designed to let a room breathe.
Internal – ultra-slim
Internal steel doors & partitions
Ultra-slim sightlines from 13mm. A profile inspired by Art Deco precision and classic industrial glazing — made for interiors where the frame should almost disappear.
Internal – maximum light
Internal steel doors & screens
The look of premium fire-rated steel glazing — without the fire-rated price. The Lumière delivers the same refined heritage appearance as the Lumière Sentinel E30, at approximately 35% less. For projects where consistency matters as much as budget.
Internal – maximum light
Internal steel doors, partitions & shower enclosures
The character of 1920s steel glazing, faithfully recreated for interiors. Designed to match the Heritage W40 external system — for projects where authenticity matters as much as architecture.
Internal – maximum light
Internal steel doors & partitions · New
A premium slim steel profile designed to move seamlessly from outside to in. The internal counterpart to the Signature External — same sightlines, same character, complete architectural continuity.

EXTERNAL DOORS & WINDOWS
The Threshold collection.
Outside, redefined.
External
Ottostumm · External steel windows & doors
Hot-rolled steel with the strength and character that cold-formed profiles can’t replicate. The Heritage is built for the projects where authentic industrial architecture isn’t an aesthetic choice — it’s the only acceptable answer.
External
The Signature
Thermally enhanced steel entrance doors
The same refined proportions as the Signature Internal — engineered for the outside. Thermally enhanced, weather-tested and designed to perform as well as it looks at the entrance to a building.
External
Thermally broken external steel windows & doors
The look of premium fire-rated steel glazing — without the fire-rated price. The Lumière delivers the same refined heritage appearance as the Lumière Sentinel E30, at approximately 35% less. For projects where consistency matters as much as budget.
External
TB PRO · Thermally broken steel doors & windows · external
Thermally broken steel at a more accessible price point. The Forge Pro brings reliable insulation, smooth operation and the quiet integrity of steel to projects where performance matters but budget is part of the conversation.
External
Thermally broken external steel windows & doors
PAS 24 certified security. Acoustic performance to 45dB. U-values to 1.2 W/m²K. Ultra-slim sightlines. The Artesa is the system for projects where every performance metric matters — and so does how it looks.
Come in with a floor plan, a question, or just a feeling. We'll start from there.

FIRE-RATED RESIDENTIAL
The Sentinel range
Protected without compromise
Fire-rated
E30 fire-rated steel doors · Internal & external
Certified fire protection without the compromise. The Sentinel delivers E30 to E120 fire resistance, acoustic performance up to 44dB and genuine steel durability — for residential and commercial projects where performance is the brief.
Fire-rated
E30 · Internal fire-rated steel doors & screens · New
E30 certified. Heritage proportions. Designed to be indistinguishable from its non-fire-rated twin. The Lumière Sentinel exists so that fire protection never has to look like fire protection.
Fire-rated
E30 · Internal fire-rated steel doors & screens
Slim, decorative and E30 certified. The Primo brings heritage glazing bar character to fire-rated steel — for interiors where protection is required but the door still has to earn its place in the room.
Fire-rated
EI30 · Internal fire-rated steel doors · New
EI30 certified — fire integrity and thermal insulation combined. The Resilience meets current UK Building Regulations for fire protection, without compromising the architectural quality of the door itself.
