Aluminium Louvre Doors & Box Louvres in Malaysia
Quick Answer
Aluminium louvre doors and box louvres in Malaysia are ventilation panels used for M&E rooms, bin centres, pump rooms, and transformer enclosures. Typical sizes are 600mm–1.2m wide and 1.8m–2.4m tall. JWE Premier fabricates standard and custom sizes in our 8,000 sq ft KL workshop, with 50+ standard configurations and 1–2 week lead time.
Fixed and adjustable aluminium louvre door systems for M&E rooms, bin centres, gas enclosures, mechanical ventilation, and architectural screening. Custom blade configurations, commercial-grade fabrication, full installation across KL and Selangor.
Aluminium Louvre Doors: What They Are & When to Use Them
Aluminium louvre doors are door systems composed of parallel angled blades (louvers) within an aluminium frame. The blades can be fixed (stationary) or operable (adjustable), allowing controlled airflow while providing visual screening, weather protection, and security. They are the standard solution for spaces that require ventilation without the security and weather exposure of an open aperture.
JWE Premier Engineering fabricates aluminium louvre doors for M&E (mechanical and electrical) rooms, bin centres, generator enclosures, gas storage rooms, plant rooms, and architectural screening applications. Our systems are specified by main contractors and consultants for commercial buildings, hospitals, factories, and shopping centres across KL and Selangor.
Types of Aluminium Louvre Systems
Fixed Louvre Doors
Blades are welded or mechanically fixed at a fixed angle (typically 30–45 degrees). Lower cost, higher airflow, no moving parts to maintain. Used where constant ventilation is required without the need for airflow adjustment.
Adjustable Louvre Doors
Blades pivot on a central rod operated by a lever or handle. Allows the user to open, close, or angle the blades to control airflow. Used where ventilation requirements vary by season or operating mode.
Box Louvres
Wall-mounted louvre panels set into a box frame. Used as intake or exhaust openings in building envelopes — typically as part of a building's HVAC system or as architectural screens for car parks, plant rooms, and service yards.
Fixed Louvre Partitions
Full-height louvre panels used as room dividers or internal screens. Common in modern commercial offices where natural airflow and visual privacy are both desired. Can be combined with glass or solid panels.
Common Applications in Malaysia
- M&E / plant rooms: Generator rooms, chiller plant rooms, lift motor rooms, switchgear rooms
- Bin centres: Refuse collection rooms in commercial buildings and condominiums — ventilation reduces odour and improves IBC compliance
- Gas enclosures: LPG storage rooms, gas meter rooms, and chemical storage requiring permanent ventilation
- Car park ventilation: Exhaust and intake louvres in basement and podium car parks
- Architectural screening: Service yards, refuse areas, and unsightly building elements concealed behind a louvre screen
- Boiler rooms: Industrial boiler and incinerator rooms requiring combustion air intake
Blade Configurations and Airflow
Louvre performance is measured by airflow coefficient and pressure drop. The configuration of blades determines how much air passes through:
- Blade depth: 50mm, 75mm, 100mm, 150mm. Deeper blades provide better weather protection but reduce airflow.
- Blade pitch: 30-degree pitch is optimal for rain rejection with 50% free area. 45-degree pitch provides maximum airflow but reduced rain rejection.
- Blade spacing: Closer blade spacing reduces see-through but also reduces free area.
- Frame depth: 100mm standard, 150mm for high-rainfall exposures.
For monsoon-exposed orientations, JWE Premier recommends a 100mm blade depth at 30-degree pitch with a 150mm frame depth. This combination rejects 95% of wind-driven rain while maintaining 40% free area for airflow.
Material Specification
All JWE Premier louvre systems use marine-grade aluminium extrusions with the following specifications:
- Aluminium alloy 6063 T5 or T6 (architectural grade)
- Wall thickness 1.2–1.8mm depending on blade size
- Stainless steel 304 or 316 fixings and operating hardware
- Polyester powder coating to 60–80 microns (15-year warranty)
- Optional anodised finish to 25 microns for coastal applications
Pricing in Malaysia (2026)
Louvre door pricing depends on configuration, blade depth, finish, and quantity. Typical 2026 rates for supply-and-install in the Klang Valley:
| System | Blade Size | Indicative Price (per sq ft) |
|---|---|---|
| Fixed louvre door | 50mm | RM 40–65 |
| Fixed louvre door | 100mm | RM 70–110 |
| Adjustable louvre door | 100mm | RM 110–180 |
| Box louvre (wall opening) | 100mm | RM 80–130 |
| Fixed louvre partition | 100mm | RM 90–140 |

Frequently Asked Questions
What is the difference between aluminium louvre doors and box louvers?
Louvre doors are door-sized louvre panels installed as access doors to M&E rooms, bin centres, and similar spaces. Box louvres are smaller wall-mounted louvre panels installed as part of the building envelope for HVAC intake or exhaust. Both use the same blade geometry but different frame configurations.
Are aluminium louvre doors secure?
Standard fixed louvre doors are not security-rated — they allow airflow and visual screening but can be defeated by determined intruders. For secure applications, we add internal mesh grilles (stainless steel or aluminium) or specify inverted-blade designs that prevent reach-through. JWE Premier can also fabricate louvre doors with integrated lockable panels.
Can louvre doors withstand heavy rain?
Yes, when properly specified. Our 100mm blade depth with 30-degree pitch and 150mm frame depth rejects 95% of wind-driven rain in laboratory testing. For monsoon-exposed installations, we add drainable blade channels and a secondary drip edge.
Do you fabricate custom blade configurations?
Yes. JWE Premier fabricates custom blades from 50mm to 200mm depth, various pitch angles, and special profiles (storm-proof, inverted, aerodynamic). Send us your airflow and rain rejection requirements and we'll design the optimal configuration.
