Overview

This technical document serves as a detailed guide for the planning, specification, and installation of folding shutters (Klappläden), emphasizing efficiency, safety, and compliance with standards. It covers product models, frame profiles, mounting types, hardware packages, ordering procedures, and advanced options including motorized drives and thermal insulation solutions.

1. Product Models and Specifications

The document catalogs over 80 folding shutter models such as JS, SUN-R75, MS, PARIS, UL, SR, GE, TIZO, and ACO series. Each model is defined by specific frame profiles, filling types (lamellae or flat panels), and dimensional ranges.

• Dimensions: Minimum and maximum widths and heights vary by model; smaller sizes may be available upon technical consultation.
• Weight: Ranges from 5 to 13 kg/m² depending on model and filling.
• Options: Include cross rails (Querfries Q60), longitudinal rails (Längsfries L60 or L15), lamella reinforcement, various arch shapes (round, pointed), slopes, and cut-outs.

2. Frame Profiles and Fillings

Frame profiles are specified with precise angles and dimensions to support different shutter designs. Fillings include lamellae and flat panels, with static elements incorporated for structural stability.

3. Mounting Types and Dimensions

Five mounting types (Montagearten 1 to 5) are described:

• Mounting with rebate (einschlagend)
• Overlay mounting (aufliegend)
• Frame mounting (Stockmontage)

Each mounting type requires specific dimensional adjustments (deductions or additions) to width and height to ensure proper fit and function. For example, width deductions range from -10 mm to -21 mm, while some types require width additions up to +40 mm and height additions of +15 mm.

4. Hardware and Fittings Packages

Hardware packages, primarily the German standard (Beschlagpaket D), include:

• Hinges (Schraubkloben) of varying lengths depending on mounting type
• Express bands (Expressband) facilitating shutter movement
• Shutter latches (Ladenriegel), handles (Handgriff), and locks (Ladenverschluss)
• Stop buffers (Anschlagpuffer) and facade dowels (Fassadendübel)
• Decorative and functional plates (Abdeckplatte, Streichblech)

Packages are organized by shutter configuration schemes (e.g., 1L/1R, 2L/2R, 3L/3R, 2LA/2RA, 3LA/3RA), indicating the number of shutter wings and hinge sides. Each scheme specifies required parts and quantities for windows and doors, including rivet counts.

5. Installation Guidelines and Accessories

Installation instructions emphasize using specific dowels, hinges, and reduction sleeves for new hardware. Minimum wall distances, shutter thickness, and clearance requirements are detailed to ensure proper shutter operation.

Accessories such as EHRET drilling templates are recommended for precise hardware mounting.

6. Ordering and Additional Information

Order forms and a webshop are referenced for procurement. Additional technical data sheets provide further options and detailed specifications.

7. Hardware Components and Part Numbers

• Fasteners and Accessories: Nylon facade dowels, RAL-colored blind rivets (4x12 mm), adhesive discs, cover plates, T-strips, and paint strips.

8. Hardware Packages and Schemes

Multiple hardware packages are detailed, including:

• Schema 4 and 4A: German Expressband systems differing in hinge types (crooked vs. straight) and component counts.
• CH 1 (Schlenggen): Swiss standard with adjustable tension straps, transparent protection, galvanized frame brackets, and angle brackets.
• CH 2 (Ladenrechen): Includes shutter stay bars, jalousie rods, and U-discs, with variations by hinge type and component quantity.

9. Installation Dimensions and Mounting Types

Standard mounting dimensions for types 1, 2, 3, 4 (overlay), and 5 (frame mounting) are provided, covering shutter overhangs, distances from window lintel, and mounting offsets to ensure correct alignment and operation.

10. Optional Features and Profiles

13. Wind Load Considerations

The Beaufort scale is referenced to describe wind speeds and their impact on shutter hardware. Key recommendations include:

• Avoid operating motorized drives during storms (wind speeds > 62 km/h) to prevent damage.
• Shutters must be closed during stormy weather.
• Maximum shutter sizes depend on bracket positioning and wind conditions; additional brackets may be required.
