One of the standout features of bifold doors is their ability to create a seamless transition between indoor and outdoor spaces when fully opened. However, achieving this seamless transition largely depends on the type of threshold you choose. A raised threshold that requires stepping over not only disrupts the aesthetic appeal but also poses safety concerns.
What is a Flush Threshold?
A truly flush threshold aligns with the finished floor level, allowing for a smooth and uninterrupted flow between indoor and outdoor spaces. While many doors in homes feature raised thresholds that require stepping over, there's no reason why most of these thresholds can't be designed to be flush with the floor level.
Types of Bifold Door Thresholds
When it comes to bifold door thresholds, there are primarily two types to consider: non-rebated and rebated.
Non-Rebated Thresholds
Key Features:
Provides a completely smooth transition from inside to outside.
The roller sits inside the section, and the flooring meets the top of the threshold on either side.
Considerations:
Lacks the same level of weather protection compared to a rebated threshold.
Ideal for sheltered positions but may not be suitable for exposed areas, as rain can potentially run down the door and find its way inside due to the absence of a protective barrier.
Rebated Thresholds
Key Features:
Offers full weather protection.
The up-stand (barrier) fits tightly against the door when closed, creating a tight seal.
Results in a slightly different level between the internal and external spaces, typically around 15mm, which is generally not considered a trip hazard or unsightly.
Considerations:
Provides superior protection against the elements, making it a popular choice among homeowners.
Achieves a relatively flush finish, allowing for a seamless transition while ensuring weather resistance.
Making the Right Choice
For many homeowners, the ability to open bifold doors and enjoy a flush transition is a top priority. However, our experience shows that protection from the elements often ranks even higher on the list of concerns. As a result, approximately 98% of our customers opt for the rebated threshold, prioritising weather resistance without compromising too much on the aesthetic appeal.
Conclusion
Choosing the right bifold door threshold is crucial for achieving both a seamless transition between indoor and outdoor spaces and adequate protection against the elements. Whether you prioritise aesthetics or weather resistance, understanding the differences between non-rebated and rebated thresholds will help you make an informed decision that best suits your needs.
