security PAS 24
Steel doors with louvred panels/cassettes compliant with PAS 24 security ratings. Side and over-panel louvres use heavy-duty rebated outer frames with secure internal fixing.
For a PAS 24 steel louvred doorset, the current reference is PAS 24:2022+A1:2024. It tests the complete doorset, and the manual attack is intended to represent a casual/opportunistic burglar rather than the much heavier tool sets used in standards such as LPS 1175
For development purposes, the attack kit includes relatively basic hand/manipulation tools. Publicly available PAS 24 test documentation shows tools such as mild-steel wire, credit-card-type plastic, paint scrapers, a craft knife, and flat/cross-head screwdrivers.

PAS 24 and STS 202 security louvre doors are tested steel doorsets that combine resistance to forced entry with permanent ventilation. The door leaf, frame, louvre panels, locks and hardware are tested as a complete security doorset.
A PAS 24 security louvre door provides enhanced protection against unauthorised access while allowing controlled airflow through secure steel louvre panels. These doors are commonly specified for residential developments, communal areas and commercial buildings.
An STS 202 security louvre door is tested against defined methods of physical attack using specified tools. It provides a robust security and ventilation solution for plant rooms, utility buildings, substations and other restricted areas.
PAS 24 is commonly specified for enhanced security in residential developments and suitable commercial premises. LPS B3 provides an alternative security classification for projects requiring tested resistance to forced entry. The correct standard will depend on the building, risk assessment and project specification.
Security-rated steel louvre doors are suitable for buildings and service areas that require ventilation and protection against unauthorised access, including:
- Plant rooms and boiler rooms
- Electrical substations
- Utility and infrastructure buildings
- Residential bin and cycle stores
- Schools and public buildings
- Warehouses and industrial premises
- Generator and equipment enclosures
Yes. Security louvre doors can be manufactured with louvre panels designed around the airflow requirements of plant, machinery and building services. The size, position and number of louvre panels can be configured to suit the required ventilation performance.
Not when the louvre door is correctly specified and tested as a complete security doorset. Reinforced louvre assemblies provide permanent airflow while helping the door maintain its tested resistance to forced entry.
Yes. Maxium Doors supplies made-to-measure security louvre doors for new-build and refurbishment projects. Available options include:
- Single security louvre doors
- Double steel louvre doors
- Leaf-and-a-half doorsets
- Fixed side and overhead panels
- Partial and full-height louvre panels
- Bespoke colours and finishes
Security louvre doors can be specified with approved single-point or multi-point locks, security cylinders, lever handles, panic hardware and access-control-compatible equipment. Locks and hardware must remain within the tested doorset specification to preserve the required security certification.
PAS 24 or LPS1175 B3 certification does not automatically make a security louvre door fire rated. Any required fire resistance must be provided by a complete doorset that has been separately tested and certified for the specified fire performance.
Yes. Maxium Doors supplies PAS 24 and STS 202 security louvre doors for projects throughout the UK. Customers can choose supply-only or professional installation, with support available for specification, measuring, manufacture, delivery and fitting.
The cost of a security louvre door depends on its dimensions, security rating, doorset configuration, louvre arrangement, locking hardware, finish and installation requirements. Contact Maxium Doors with your opening sizes, required certification and site postcode for a tailored quotation.
