DOUBLE LAYER DIVIDING CURTAIN
Product Code: D302
Motorized Double Layer Dividing Curtain System with Advanced Acoustic Performance
The Double Layer Dividing Curtain System D302 is a high-performance solution designed for division of large indoor spaces with enhanced acoustic performance, such as sports halls, gymnasiums, multipurpose arenas and industrial buildings.
The system features a double layer curtain construction, which provides excellent sound absorption and significantly reduces noise transmission between divided areas. This makes it the best acoustic solution within dividing curtain systems, ideal for environments where multiple activities take place simultaneously.
For projects with higher acoustic requirements, an advanced version D302-TA (Top Acoustic) is available, achieving sound reduction up to 22 dB.
The system enables full-height separation from floor to ceiling, creating completely independent zones. The curtain material is fully opaque, ensuring that light does not pass through, which enhances visual separation.
In addition to acoustic performance, the double layer curtain also provides impact absorption, making it suitable for sports environments where ball contact or minor impacts frequently occur.
Despite its double-layer construction, the system is designed as a lightweight solution, minimizing structural load.
The system is engineered as a complete modular solution, with all components integrated into a self-supporting aluminium truss structure, ensuring reliability and fast installation.
The D302 system represents a premium solution for space division with acoustic control.

Aluminium Truss Carrier Structure
The 40 × 40 cm aluminium truss is exclusively manufactured in a torsion-resistant configuration and features reinforced aluminium profiles for increased structural performance.
Its optimized design ensures excellent behaviour under both concentrated and distributed loads, even across long spans. Torsional rigidity has been significantly enhanced through an improved diagonal tube configuration, providing superior stability and reliability.
Specifically engineered for dividing curtain systems, this truss enables the creation of both small and large partitioned areas while maintaining exceptional structural integrity under operational loads. The truss incorporates the complete drive assembly, including the motor, drive shaft, bearings, support brackets and safety braking system, resulting in a compact and efficient solution.
The aluminium truss is designed for quick and straightforward installation and can be configured in various mounting arrangements, including direct roof attachment or suspended ceiling installation.
Motor Drive System
Elektromaten drives are specifically designed for dividing curtain applications, ensuring reliable operation, precise control and long-term performance.
Depending on the system configuration, the drive unit can be connected directly to the drive shaft or operated through a chain transmission. To guarantee maximum safety, each system is equipped with an appropriately sized safety brake that prevents unintended curtain movement in the event of power loss or mechanical failure.
The drive unit is selected individually based on the dimensions, weight and operational requirements of each curtain system.
Safety Brake System
The safety brake features a compact design with uniform external dimensions across all sizes, simplifying system integration and installation. A visual status indicator clearly displays both operating and braking positions, allowing quick verification of the brake condition.
Designed for maximum reliability, the brake is maintenance-free and self-monitoring, ensuring consistent performance throughout its service life. It is suitable for operating speeds of up to 45 rpm and includes an IP65-rated safety switch for secure integration into the safety circuit.
The safety brake is activated automatically if the maximum operating speed is exceeded. Its locking mechanism, consisting of a ratchet wheel and locking catch, immediately initiates the braking process. An optimized tooth geometry minimizes reaction time and braking distance while reducing braking forces transferred to the supporting structure. This ensures safe, controlled stopping and long-term protection of the entire dividing curtain system.
The safety brake is selected individually based on the dimensions, weight and operational requirements of each curtain system.
Integrated Drive Shaft and Winding System
All components of the drive shaft and winding mechanism are fully integrated within the aluminium truss carrier structure, creating a compact, protected and highly efficient system. This integrated design minimizes installation complexity while ensuring optimal performance, reliability and ease of maintenance.
The modular system is engineered to provide maximum flexibility and consists of all essential mechanical, structural and safety components, including:
- Motor assembly and mounting brackets
- Drive and support shafts
- Bearings and safety brake system
- Roof suspension and fixing brackets
- Winding discs and curtain support elements
- Structural connectors and locking components
- Protective and alignment elements
- Belt and tensioning system
- Reinforced aluminium profiles and truss components
- Fasteners, pins, dowels and installation accessories
Each component is designed to work seamlessly within the integrated system, ensuring smooth operation, precise curtain movement and long-term durability under demanding operating conditions.
PVC Curtain Material
Our premium PVC curtain material combines advanced weaving technology with a high-quality coating system to deliver exceptional durability, performance and appearance. The specially engineered surface ensures smooth and consistent rolling and folding behaviour, making it ideally suited for dividing curtain applications with frequent operation.
The material offers excellent dimensional stability, with minimal elongation under tension, ensuring reliable performance and maintaining a clean, professional appearance throughout its service life. Its robust construction also provides high resistance to bending and deformation, even in demanding environments.
Key Features
- Flame-retardant material for enhanced safety
- Excellent rolling and winding characteristics
- High dimensional stability and low elongation
- Superior resistance to wind loads and air pressure
- Durable textured surface finish
- Suitable for a wide range of sports facility applications
