From certified emergency evacuation escape routes to high-load weather-resistant perimeter envelopes, explore our precision-built aluminium fenestration and entrance systems specified worldwide.
Under the European Construction Products Regulation (CPR 305/2011), external fire-rated pedestrian doorsets must bear the official CE marking under harmonised standard EN 16034:2014 in direct conjunction with EN 14351-1:2006+A2:2016. For internal fire escape doors, the standard couples with EN 14351-2. This regulatory framework verifies that every fire exit doorset fabricated from aluminium alloy profiles is not assessed merely as isolated components, but as a fully tested, factory-controlled complete assembly comprising the frame, leaf, fire-resistant glazing, intumescent seals, hinges, closing mechanisms, and certified panic panic hardware.
Unlike standard steel doors that suffer from excessive weight, thermal expansion warping, or severe corrosion risks in humid environments, modern CE certified aluminium fire exit doors utilize 6063-T6 or 6061-T6 architectural grade aluminium alloys integrated with high-density polyamide thermal breaks (PA66 GF25) and specialized intumescent core materials. These engineered assemblies are subjected to rigorous full-scale furnace exposure tests under EN 1363-1 and EN 1634-1 to classify their mechanical and thermal endurance:
Measures the assembly's mechanical capacity to prevent flames, combustible hot gases, and toxic combustion products from penetrating to the unexposed face under furnace pressures exceeding 20 Pa.
Evaluates heat flux mitigation. EW-rated doors prevent radiation levels on the unexposed face from exceeding 15 kW/m² at an empirical distance of 1.0 meter, protecting human escapees from severe burns.
The highest safety threshold. EI30, EI60, EI90, and EI120 doors limit the unexposed surface temperature rise to an average of ≤140°C (maximum peak ≤180°C above ambient), preventing radiant flashover ignitions.
| Classification | Integrity (E) | Insulation (I) | Panic Exit Standard | Typical Architectural Application | Compliance Status |
|---|---|---|---|---|---|
| EI 30 / E30 | ≥ 30 Minutes | ΔT ≤ 140°C (30m) | EN 179 (Emergency) / EN 1125 (Panic) | Commercial office corridors, residential stairwells | CE Compliant |
| EI 60 / EW60 | ≥ 60 Minutes | ΔT ≤ 140°C (60m) | EN 1125 Horizontal Push Bar | Hotels, hospital egress zones, data center utility exits | CE Compliant |
| EI 90 | ≥ 90 Minutes | ΔT ≤ 140°C (90m) | EN 1125 Heavy-Duty Panic Bar | Shopping malls, airport terminals, sports stadiums | CE / AS 2047 |
| EI 120 | ≥ 120 Minutes | ΔT ≤ 140°C (120m) | EN 1125 Multi-Point Panic Latch | Industrial chemical plants, transformer rooms, subway stations | UL 10C / CE |
| Smoke Control (Sa / S200) | Pressure Tested | Cold & Warm Smoke Gas Seal | Automatic Door Closers EN 1154 | Pressurized escape routes, multi-storey elevator lobbies | Mandatory Annex |
A fatal misconception in commercial fenestration procurement is treating emergency doors and panic exit doors identically. Building codes strictly differentiate between the two scenarios based on occupant psychological states and building familiarity:
Designed specifically for spaces accessed by the general public who have no prior knowledge of building layout (retail centers, convention halls, theaters, and international transit terminals). Requires a horizontal crossbar or touch-bar spanning at least 60% of the leaf width. Releases reliably under a push force not exceeding 80 Newtons, even under a lateral evacuation crush load of up to 1,000 N applied against the door leaf.
Permitted exclusively in environments where occupants are fully familiar with the emergency exits and a chaotic stampede is improbable (private corporate offices, server rooms, machine rooms, and industrial back-of-house areas). Employs push-pads or lever handles that unlatch instantaneously with a single intuitive motion exerting less than 70 Newtons operating effort.
How progressive developers, specifiers, and EPC contractors are reshaping high-safety commercial envelope procurement to balance life protection, operational sustainability, and smart city architectures.
Traditional purely mechanical panic hardware is rapidly converging with integrated access control. Future procurement mandates EN 13637 electrically controlled exit systems. These smart assemblies combine fail-safe electromagnetic locks, delayed egress timer delays (15 to 30 seconds for anti-theft containment), and instant override relays synchronized directly with central fire alarm panel triggers (FAS) and building automation systems (BAS).
Architects historically rejected fire exit doors due to bulky, industrial profile aesthetics. The newest generation of aluminium fire exit systems incorporates micro-porous silicate fire gel interlayers and multi-chamber internal steel reinforcements. This enables sightlines down to 65mm with clear vision panes up to 3000mm in height, preserving luxury architectural transparency without surrendering 60-minute fire barriers.
Global developers now evaluate suppliers on their Environmental Product Declarations (EPD). Primary aluminium processing accounts for high carbon emissions; leading exporters now implement hydro-powered scrap-recycled billet extrusions yielding less than 4.0 kg CO² per kg of aluminium, combined with Cradle to Cradle (C2C) certified powder coats and non-toxic intumescent foaming compounds.
