Bi-folding Door Thresholds FAQs

What is an aluminium bi-fold door threshold?

An aluminium bi-fold door threshold is a specific type of threshold designed for bi-fold doors. It is the horizontal component that sits at the bottom of the door opening and creates a smooth transition between the indoor and outdoor spaces when the bi-fold doors are folded or opened. The aluminium material used in the threshold provides strength, durability, and weather resistance. It is designed to prevent water, drafts, and debris from entering the interior while ensuring ease of movement for the bi-fold doors. The threshold is typically engineered to meet specific performance standards, including water resistance, thermal insulation, and structural integrity.

Standard Threshold: This is the most basic and commonly used threshold option for bi-fold doors. It provides a simple, low-profile design that offers a smooth transition between indoor and outdoor spaces.

Can aluminium bi-fold thresholds be installed both indoors and outdoors?

Aluminium bi-fold door thresholds can be installed both indoors and outdoors, providing a seamless transition between indoor and outdoor spaces.

How do I choose the right aluminium bi-fold threshold for my specific needs?

To choose the right aluminium bi-fold door threshold, consider factors such as the intended application (residential or commercial), weather conditions, desired level of water resistance, aesthetic preferences, and building code requirements. Consult with manufacturers, suppliers, or professionals to discuss your specific needs and select a threshold that meets your requirements.

What threshold options are available for bi-fold doors?

Weathered or Drip-Track Threshold: This threshold option includes a weathered or drip-track design that helps to direct water away from the interior space. It features a slight slope or channel to ensure water drains away from the door and prevents it from seeping inside.

Flush Threshold: A flush threshold is designed to create a seamless transition between indoor and outdoor areas. It sits completely level with the floor surface, eliminating any potential trip hazards and allowing for a smooth, uninterrupted flow between spaces.

Low-Threshold or Low-Profile Threshold: This option is particularly beneficial for accessibility and compliance with building regulations. It features a reduced height, making it easier for wheelchair users or individuals with mobility challenges to navigate the doorway.

Part-M Threshold: A Part-M compliant threshold is specifically designed to meet accessibility requirements, providing a level, low-profile surface for easy access by wheelchair users or individuals with mobility impairments.

Thermal Break Threshold: A thermal break threshold is engineered to minimize heat transfer and enhance energy efficiency. It incorporates insulation materials or design features that help to reduce thermal bridging, preventing heat loss or gain through the threshold area.

Customizable Thresholds: Some manufacturers offer customizable threshold options, allowing homeowners to tailor the design, height, width, and finishes to suit their specific needs and aesthetic preferences.

What are the advantages of a weathered bi-fold door threshold?

1. Improved Weather Resistance: The weathered design of the threshold helps to direct water away from the interior space. It features a sloped or channelled profile that promotes water drainage, preventing water from entering the building even during heavy rain or storms. This enhanced weather resistance helps to keep the interior space dry and protected.

2. Minimized Risk of Water Infiltration: The sloped or channelled design of a weathered threshold reduces the risk of water infiltrating the building. By effectively channelling water away from the door system, it minimizes the chances of water seepage, which can cause damage to flooring, furnishings, and other interior elements.

3. Enhanced Protection Against Air and Drafts: The weathered threshold helps to create a tighter seal between the door and the threshold. This improved sealing capability reduces air leakage and drafts, contributing to better insulation and energy efficiency in the building. It helps to maintain a comfortable indoor environment and reduces heating or cooling costs.

4. Efficient Drainage of Condensation: In addition to handling external water, a weathered threshold can also aid in the drainage of internal condensation that may occur on the bi-fold doors. The sloped or channelled design allows any moisture to flow outwards, preventing the accumulation of condensation on the threshold itself.

5. Suitable for Exposed or Coastal Locations: Weathered thresholds are particularly advantageous in locations that are prone to heavy rainfall, strong winds, or coastal environments. The design helps to withstand and divert water away, providing increased durability and longevity for the bi-fold door system.

What are the advantages of a non-weathered threshold?

The advantages of a non-weathered bi-fold door threshold include a sleek and seamless aesthetic, ease of access, and versatility. With its level surface, a non-weathered threshold provides a smooth transition between indoor and outdoor spaces, creating a visually appealing and uninterrupted flow. It eliminates any tripping hazards that may be present with raised or sloped thresholds, making it more accessible for all individuals, including those with mobility challenges. Non-weathered thresholds are versatile and suitable for interior applications or protected outdoor areas where water infiltration is not a concern, offering design flexibility without compromising on functionality.

Why do you need drainage on your bi-fold door?

Drainage is needed with bi-fold doors to prevent water infiltration into the interior space, protect structural integrity, maintain a dry environment, and preserve the performance and longevity of the doors.

What drainage systems are available for bi-fold doors?

Concealed drainage: Water exits the bottom track through the polyamide break barrier and enters the top of the cill. From there, it travels through the front section of the cill and out of the very front edge underneath.

Face drainage. Water enters the lower chamber of the track and exits via a capped hole in the outer face. It is common place to then put an drain in front of the door track which will route the water to a drain.

Are aluminium bi-fold thresholds easy to install?

Aluminium bi-fold door thresholds are designed to be relatively easy to install, especially when done by experienced professionals. The specific installation process may vary depending on the door system and manufacturer, but comprehensive installation instructions and guides are typically provided to facilitate a smooth and efficient installation process.

Are aluminium bi-fold thresholds suitable for commercial applications?

Yes, aluminium bi-fold door thresholds can be suitable for commercial applications. They offer durability, strength, and weather resistance, making them well-suited for high-traffic areas and commercial environments. The versatility of bi-fold doors allows for flexible use in retail spaces, restaurants, offices, and other commercial settings, and the thresholds can be customized to meet specific requirements and regulations.
