It offers peace of mind by ensuring that your home stays protected, no matter the weather outside.
Non-Weathered Threshold
On the flip side, if you’re looking for a sleek, modern look with easy access, the non-weathered threshold could be just what you need.
This type of threshold is flush with the floor, meaning there are no raised lips or barriers, creating a seamless, smooth transition from inside to outside.
Aesthetic Appeal:
- Seamless Integration: The non-weathered threshold is ideal for creating a smooth, uninterrupted look in your home. It’s perfect for those who want their bifold doors to blend seamlessly with the flooring, offering a clean, minimalistic aesthetic.
- Flat Transition: Because there is no raised section, the non-weathered threshold makes it easier to walk through, eliminating any trip hazards. This feature is especially important for households with small children or elderly members.
Best for Sheltered Areas or Internal Use:
- Ideal for Sheltered Spaces: While the non-weathered threshold offers fewer weather-resistant features, it’s still a great choice for sheltered outdoor spaces, like a covered porch or balcony, where rain and wind aren’t a major concern.
- Perfect for Indoor Use: This type of threshold works wonderfully for interior doors, creating a seamless transition between rooms or spaces in the house.
Recommended Use: If your bifold doors are used primarily in sheltered environments or indoors, the non-weathered threshold provides a sleek look with easy access.
Mobility Threshold
If you or a family member has mobility challenges, the mobility threshold is designed with accessibility in mind.
This threshold option has a lower profile, which makes it easier to navigate, especially for individuals using wheelchairs, walkers, or crutches.
Features & Applications:
- Designed for Accessibility: With its low-profile design, the mobility threshold ensures that there are no barriers or raised sections to cross, making it easy to move through the doorway. This threshold is also compliant with accessibility standards, ensuring that your home is safe and convenient for everyone.
- Ideal for Elderly or Mobility-Impaired Individuals: If you have elderly family members or those with limited mobility, a mobility threshold is a great way to ensure that your home remains accessible without sacrificing the look or function of your bifold doors.

Threshold Dimensions and Options
When selecting the right threshold for your aluminum bifold doors, it’s important to understand how dimensions and design choices can affect both the functionality and overall look of your doors.
The threshold height, clearance, and transition style you choose will impact everything from door operation to weather protection and accessibility.
Let’s explore the key factors in more detail.
Standard Threshold Heights and Door Clearance
Choosing the right threshold for your aluminum bifold doors involves understanding the dimensions and available options, as they impact both aesthetics and functionality.
Standard thresholds typically range from 15mm to 30mm, offering durability and performance suitable for most residential and commercial settings.
A higher threshold provides better protection against the elements but may require more clearance, while a lower threshold ensures smoother movement and reduces tripping hazards, making it ideal for homes with accessibility needs.
The clearance needed for your bifold door is directly related to the threshold height.
A higher threshold may create a slight elevation between the floor and the door, which could affect the clearance of the door panel when opening or closing.
For homes where accessibility is a priority, especially those with wheelchair users or elderly residents, a lower threshold ensures a smoother transition and a safer environment.
Comparison of Ultra-Low and Standard Thresholds
When comparing ultra-low and standard thresholds, ultra-low thresholds are favored for their sleek, minimalist design and accessibility benefits.
These thresholds are often used in indoor spaces or sheltered outdoor areas where weather resistance isn’t a major concern.
Ultra-low thresholds are ideal for creating a clean, modern look and ensuring an easy transition, free of any raised barriers.
Standard thresholds, on the other hand, offer better weather protection and are more suitable for external doors exposed to harsh conditions.
They provide a good balance of durability and performance, making them ideal for areas with higher foot traffic or exposure to the elements.
Standard thresholds often incorporate features like a lip or slight rebate that helps channel water away from the interior, keeping your space dry and secure.
Optional Cill Integration for Seamless or Stepped Transitions
Another consideration is the transition type: a seamless or stepped design with a cill.
A seamless transition creates a smooth, uninterrupted flow from indoors to outdoors, perfect for internal bifold doors or when a modern aesthetic is preferred.
This design can create a visually appealing, continuous look that enhances the indoor-outdoor connection, especially in spaces with minimal weather exposure.
However, for external applications, a stepped transition with a cill is a better choice, as it helps prevent water from entering the building while also providing additional weather resistance.
The cill design, paired with a weathered threshold, is particularly beneficial in areas exposed to rain or strong winds.
A stepped threshold can also add a stylish dimension to the overall door design while providing enhanced performance.
Ultimately, the right threshold dimension and transition style depend on the specific needs of your space, balancing accessibility, aesthetics, and weather protection.
Whether opting for a sleek ultra-low threshold or a durable stepped transition, there’s a solution that will ensure both functionality and style.
Choosing the right option can ensure a smooth and safe operation while enhancing the overall look of your bifold door system.
Drainage Systems for Bifold Door Thresholds
Proper drainage is crucial to prevent water pooling and protect your bifold doors from damage.
Two common drainage options for bifold door thresholds are face drainage and concealed drainage.
Face Drainage
Face drainage works by allowing water to exit through capped holes in the outer face of the threshold.
It’s ideal for areas with mild exposure to weather, offering a straightforward solution for internal spaces or sheltered outdoor areas.
While easy to maintain, it may not provide the best protection in heavy rain or strong winds.
Concealed Drainage
Concealed drainage directs water through a polyamide break barrier into a cill, offering a cleaner, hidden design.
This option provides better weatherproofing and is perfect for areas exposed to harsh weather conditions.
It ensures water is efficiently directed away from the interior, enhancing durability and aesthetic appeal.
Why Drainage Is Essential
Effective drainage prevents water from pooling in the door track, which can lead to damage.
Whether you choose face or concealed drainage, both systems ensure your bifold doors remain functional and protected from water-related issues.
