The CF77 threshold choices are a fully flat version, ideal for internal applications where you want the floors on either side of the bifold door set to be flush with no weather rating. There’s a low threshold design, suitable for commercial environments and a double weather-sealed design, with some level of weather protection. There’s then the fully weathered design with a High-Performance option.

Bifold doors frequently asked questions
Our Reynaers bi-folding doors meet the requirements of both commercial and residential projects. Answers to our popular questions about bifolding doors.
Why are bifold doors going out of fashion?
Some reasons often cited for the waning popularity of bifold doors include their reduced glass usage compared to sliding doors. While sliding doors boast slender frames, bifold designs prioritize durability and incorporate more hardware. This translates to enhanced home security, with multi-point locks and a tamper-resistant in-line slider that thwarts break-ins.
Unlike sliding doors, bifold models can neatly tuck away into corners, seamlessly connecting your home to the outdoors while maintaining safety. A concern raised about bifold doors is their cost, which can initially appear high. In contrast, more budget-friendly options like French doors exist. However, these alternatives may not elevate your property’s value as significantly and could offer inferior performance.
Modern bifold doors utilize advanced double glazing and offer a choice between sturdy uPVC or robust aluminium frames. Furthermore, the design of bifold doors has proven to increase property value, potentially resulting in a higher resale price. Bifold doors provide an all-encompassing solution to modern living. With uPVC or aluminium frames, they establish an efficient entry that can replace a wall while maintaining insulation. The sleek design ensures unobstructed views of the surroundings.
Beyond their impressive open configuration, bifold doors excel when closed. They provide a fully weatherproof, airtight, and watertight barrier that enhances insulation, warmth, and energy savings.
What are the disadvantages of bifold doors?
Cleaning and Maintenance Challenges: Both bifold doors and sliding doors present difficulties in cleaning the tracks. Bifold doors, with their multiple folding layers, can be especially challenging to clean. This cleaning issue stands out as the primary drawback of Bi-fold Glass Doors. Over time, the flexibility of the hardware within the central fold can deteriorate. Moreover, when these larger doors are folded or ‘open,’ they occupy a significant amount of space.
Accessibility Challenges: A notable inconvenience of bi-fold doors is the hindrance they create when moving from one side to the other. Opening the entire door can introduce a rush of freezing air, particularly troublesome during winter. While this might not be an issue if an alternate access door is nearby, it could pose a problem if such a door is unavailable. Addressing this, certain bi-fold door models, such as the one offered by Cover Glass, include an additional panel at the door’s end to facilitate easy movement in and out. Our system opens from both extreme ends, customizable to open inward or outward, granting you full control over its operation.
Absence of Threshold: Folding glass doors lacks a raised threshold, which is advantageous for safety. However, improper fitting can lead to issues. Inadequate drainage can result in water accumulation due to the low level of bifold doors. Cover Glass has anticipated this concern, ensuring proper drainage with weep holes at the system’s base and UV-protected weather strips between panels to ensure a secure seal.
Frame Abundance: Bifold doors are characterized by numerous frames, with each folding pane having its own frame. This can slightly obstruct the view when the doors are closed. To mitigate this, frames can be designed to be as slim as possible. Alternatively, the option of going frameless exists. Cover Glass provides frameless glass doors that our customers highly appreciate. The transformative impact of eliminating frames on a home’s appearance is remarkable. It imparts a genuinely open and inviting ambience that framed systems cannot achieve.
What is better than a bifold door?
Bifold doors, known for bringing the outdoors inside, have gained immense popularity. To differentiate them from sliding doors, consider their features. Bifold doors fold back in a concertina style, composed of connected panels that run on concealed tracks. Sliding doors consist of large glass panes that slide sideways. The key distinction lies in bifold doors requiring space for panels to stack, unlike sliding doors. Bifold doors offer full openness, expanding indoor-outdoor space. Sliding doors usually open partially, though pocket doors can enhance this. Sliding doors grant more control, with options for slight breezes to full outdoor access. Aesthetically, sliding doors provide larger glass areas and more natural light. Bifold doors have visible vertical frames when closed. Thresholds vary, with bifold doors allowing flush or low thresholds, facilitating accessibility. Costs are similar unless doors are large, whereas sliding doors become costlier due to glass units. Thermally, sliding doors are more efficient due to less frame. Both types can comply with insulation standards. Bifold and sliding doors are light, easy to use, and available in various materials. Personal preference plays a role in choosing between them.
