Louvred Steel Doors
Secure, ventilated steel doors for plant rooms, substations, and block management. Expertly supplied and installed for asset managers and contractors.
Our louvred doorsets are built heavier than our standard doors — 2.0mm steel across the leaf, frame and louvre blades — with a blade profile giving approximately 50% free air area. That means constant ventilation for plant and electrical equipment without creating a weak point in your security line.
Maximum Ventilation, Uncompromising Security
When your building infrastructure requires continuous airflow, standard steel doors won’t work. Entrad’s louvred steel doors are the perfect solution for plant rooms, boiler houses, server rooms, and bin stores, offering essential ventilation without sacrificing physical security.
We work closely with landlords, block managers, and school administrators to supply and fit made-to-measure louvred doors. Designed to keep out harsh weather, pests, and unauthorised personnel, our doors ensure your critical machinery and utility areas remain safe, secure, and fully operational.

Constant airflow for pumps, AHUs and switchgear, with the room locked behind heavy-gauge steel. Louvre positions are specified to suit your ventilation calculations.
Substation doors
Secure, ventilated access for electrical substations and switch rooms, with multi-lock options and Grade 3 furniture for authorised-only entry.
Bin store doors
Ventilated bin store and refuse room doorsets that control odour build-up while resisting vandalism and unauthorised access — a common requirement for residential blocks and managed sites.
Boiler room doors
Combustion air supply for boiler and plant spaces, delivered through the doorset itself where wall vents aren’t practical.
Sizes & Configurations
Louvred doorsets are made to measure — single doors up to approximately 1350mm × 2800mm structural opening, and double doorsets up to approximately 2650mm × 2800mm. Full-height or part-louvre configurations are available on both.
Louvred Steel Door FAQs
What is a louvred door used for?
Ventilating spaces that must stay locked: plant rooms, electrical substations, switch rooms, bin stores and boiler rooms. The louvre blades allow constant airflow while the steel doorset keeps the space secure.
How much airflow does a louvred steel door provide?
Our louvre blade profile provides approximately 50% free air area across the louvred section — sufficient for most plant and electrical ventilation requirements. If your M&E consultant has specified a required free area, we’ll configure the louvre panel to suit.
Are louvred doors secure?
Yes. Our louvred doorsets use 2.0mm steel for the leaf, frame and blades — heavier than a standard doorset — with Class 14 hinges, Grade 3 (BS EN 1906) furniture and multi-lock options.
Can I have a part-louvred door?
Yes — louvre panels can be full-height or partial, on single or double doorsets, positioned to match your airflow requirements.
