SUNFLEX aluminium bifold doors
High-performance bifold doors for contemporary living
SUNFLEX bifold doors are designed to create wide, unobstructed openings between the home and garden while maintaining strong thermal and weather performance when closed. The SF75eco is the current high-performance aluminium system within the range.
The SF75eco combines slim aluminium frames with advanced thermal-break technology, independently tested weather performance and PAS 24 security capability. The system is designed for both double and triple glazing and can be configured for a wide range of residential openings.
SUNFLEX also offers specialist bifold configurations including low-threshold options, open-corner arrangements and large-format panels, allowing the door design to respond to the architecture of the project rather than relying on a standard layout.
Cedar Views supplies and installs SUNFLEX bifold doors, with selected systems available to view at our Chobham and Longacres showrooms. We help clients review opening size, threshold detail, glazing, exposure and configuration before the final system is specified.

See how the SF75eco bifold door works
The SF75eco is SUNFLEX’s high-performance aluminium bifold door system, designed to combine slim 117mm sightlines with advanced thermal efficiency, strong weather protection and flexible configuration options. In this SUNFLEX product video, the key features of the SF75eco are explained, including its thermal-break design, antiSLAM panel catch, in-line handles, track options and overall operation. Cedar Views can help you review whether the SF75eco is appropriate for your opening size, threshold detail, glazing requirement, exposure and overall project specification.
In-line handles for a cleaner bifold door finish
The SF75eco uses in-line handles designed to sit neatly within the door profile, helping reduce visual interruption and maintain a cleaner appearance across the glazed panels.
Handle options are coordinated with the door frame, with the lead door using an in-line lever handle and the folding panels using flush in-line handles to operate the locking points. A more conventional horizontal handle can also be specified where appropriate.
antiSLAM panel catch for safer everyday use
The SF75eco incorporates SUNFLEX’s antiSLAM panel catch, designed to hold the lead door securely against the adjacent panel when the bifold doors are fully open. This helps reduce the risk of the door moving unexpectedly in use, for example in windy conditions or busy family spaces.
03 · Key benefits
Key benefits of SUNFLEX SF75eco bifold doors
117mm slim sightlines
The SF75eco uses 117mm sightlines, helping maximise the glazed area while retaining the strength and stability required for large aluminium bifold panels.
Advanced thermal performance
A patented 44mm thermal break and support for double or triple glazing allow the SF75eco to achieve U-values from 1.2 W/m²K double glazed and from 0.8 W/m²K triple glazed, subject to the glass specification.
Tested weather protection
The SF75eco has independently tested performance for air permeability, water tightness and wind resistance, with results dependent on track type, panel sizes and configuration.
PAS 24 security
Multi-point locking, shoot-bolts and lead-door locking are designed to support PAS 24 compliance when the door is specified in the appropriate tested configuration.
Low-threshold or weathered track
Choose between a 14mm low-threshold option for a reduced step or a 35mm double-rebated weathered threshold where greater protection from the elements is required.
Flexible panel configurations
Panels can be specified up to 1200mm wide and 3000mm high, with options including open corners, curved sets and different folding arrangements, subject to project design and specification.
