Overview

The Henderson Bifold system is a comprehensive solution for installing bifold doors, designed to provide smooth operation and versatile configurations. This manual provides detailed fitting instructions, technical specifications, and usage guidelines for various bifold door setups.

Function Description:

The Henderson Bifold system enables the installation of multiple door panels that fold and stack, allowing for wide openings and efficient space utilization. It supports different stacking configurations, including doors that stack perpendicular to the opening (Layout 1) and doors that stack at an angle to the opening (Layout 2). The system is designed for both residential and commercial applications, offering robust components for long-lasting performance. Key components include a top track, bottom pivot, top pivot, sliding guide, and various fixings. The system accommodates different door panel widths and weights, ensuring flexibility in design.

Important Technical Specifications:

Door Weight and Dimensions:

  • Maximum Door Weight: 14 kg per door panel.
  • Minimum Door Thickness (B): 18-35 mm.
  • Maximum Door Width (A): 610 mm.
  • Minimum Headroom (H): The headroom (H) is calculated as Z - (35-40) mm, where Z is the overall height of the door opening. This ensures sufficient clearance for the top track and pivots.
  • Minimum Side Clearance: 16 mm on the pivot side and 3 minutes on the sliding guide side.

Component Specifications:

  • Top Track (No. 310, No. 311, No. 313, No. 314, No. 315, No. 316): The top track is the primary support for the bifold doors, guiding the top pivots and sliding guides. It is fixed to the lintel or frame above the opening.
  • Bottom Pivot (No. 312): This component is installed at the bottom of the first door panel, providing a fixed pivot point for the door to rotate.
  • Top Pivot (No. 319): Located at the top of the first door panel, the top pivot engages with the top track, allowing the door to swing.
  • Sliding Guide (No. 282HD): This component is installed on subsequent door panels (typically the second door in a multi-panel setup) and slides within the top track, facilitating the folding and stacking action.
  • Fixings:
    • 8G x 16 Pan Head screws are used for securing various components, including the top track and sliding guide.
    • 6G x 19 CSK screws are used for specific track installations.
    • 7G x 25 CSK screws are used for attaching hinges and other components to the door panels.

Door Panel Configurations (Y dimensions):

The system supports various door panel configurations, with specific Y dimensions (width of the door opening) for different kit types:

  • B10/2 Kit: Y = 915 - 1067 mm. This configuration typically involves two door panels.
  • B15/4 Kit: Y = 1068 - 1525 mm. This configuration typically involves four door panels.
  • B20/4 Kit: Y = 1526 - 2135 mm. This configuration typically involves four door panels.
  • B25/4 Kit: Y = 2136 - 2461 mm. This configuration typically involves four door panels.

Hinge Calculations:

The manual provides formulas for calculating the required hinge dimensions (A) based on the opening width (Y) for different numbers of door panels:

  • 2 Panels: A = Y - 14 mm.
  • 4 Panels: A = Y - 20 mm.
  • 6 Panels: A = Y - 24 mm.
  • 8 Panels: A = Y - 28 mm. These calculations ensure proper spacing and functionality of the bifold doors.

Usage Features:

Installation Flexibility:

The Henderson Bifold system offers two primary layout options for door stacking:

  • Layout 1 (Perpendicular Stacking): Doors stack perpendicular to the opening, providing a clean and compact stack. This is achieved by installing the sliding guide at a fixed distance (D = 30 mm) from the edge of the door.
  • Layout 2 (Angled Stacking): Doors stack at an angle to the opening, which can be useful in situations where perpendicular stacking is not feasible or desired. The position of the sliding guide (D) for angled stacking depends on the number of door panels:
    • For 18-24 mm door thickness (B), D = 22 mm.
    • For 25-35 mm door thickness (B), D = 17 mm. This flexibility allows for adaptation to various architectural designs and space constraints.

Smooth Operation:

The combination of top-hung track, bottom pivot, and sliding guides ensures smooth and effortless operation of the bifold doors. The components are designed to minimize friction and provide stable movement, even with heavier door panels.

Adjustability:

The system allows for some adjustability during installation to ensure perfect alignment and operation. The bottom pivot and top pivot can be adjusted to fine-tune the door position and ensure proper engagement with the track.

Comprehensive Kit:

The system is available in various kit types (B10/2, B15/4, B20/4, B25/4) that include all necessary components for a complete bifold door installation, simplifying the purchasing process. Note that the B10/2 kit does not require the specific component shown in Diagram 6 (likely a specialized bracket or guide for multi-panel systems).

Maintenance Features:

Durable Components:

The components are manufactured from robust materials, designed to withstand regular use and provide long-term durability. This minimizes the need for frequent maintenance or replacement.

Easy Cleaning:

The exposed surfaces of the track and hardware can be easily cleaned with a damp cloth to remove dust and debris, maintaining smooth operation.

Lubrication:

While not explicitly detailed in the provided excerpts, typically, bifold door systems benefit from periodic lubrication of the sliding guides and pivots with a suitable lubricant (e.g., silicone spray) to ensure continued smooth operation and prevent wear.

Inspection:

Regular inspection of the track, pivots, and sliding guides for any signs of wear, damage, or loose fixings is recommended. Any worn or damaged components should be replaced promptly to maintain the safety and functionality of the bifold doors.

Part Number and Issue Information:

The manual is identified as Part Number: 300418, Issue 6, dated December 2011, indicating that it is a revised and updated version of the instructions, reflecting ongoing product development and improvements.
