The Slimmest Sightlines

If you want to open up to 90% of your elevation, ultra slim bifolding doors offer a modern, high-quality option suitable for large openings and long elevations of sliding folding glass.  

The slim framed aluminium bifolding doors can be designed in a range of configurations including bi-parting and corner opening arrangements without a restriction on the number of bi-folding panes. 

These slim bifold doors are a popular option for modern living areas or spaces where the inside and out are to be merged. Slim square framing and a flush floor finish from inside to out are key factors in merging inside and out. 

Bespoke Bifold Door Designs

To enhance the indoor-outdoor living design, IQ's ultra slim bifold doors are manufactured with structurally bonded glass and internal glazing beads. This design provides ultra-slim, thermally broken aluminium profiles for minimal visual obstruction of the surrounding scenery. 

Every junction and detail of these sliding folding doors are designed to maintain a modern, square edge finish to the frame and offer the slimmest frame junctions available for aluminium bifolding glass doors. IQ Glass will detail and design all fixing and connection details in full as part of our in-house design service. 

All of our ultra slim bifold door systems can be specified with a range of glazing options and have a wide variety of frame finishes available, meaning they can be designed to suit any project type. 

Steel Look Bifold Doors

For a more traditional bifold door design, bespoke glazing bars can be integrated into the design of the Sieger aluminium bifolding doors to recreate a traditional timber or steel framed door system but with a durable, low maintenance finish suitable for all project types and designs. 

An aluminium bifolding door is the best way to create a steel look bifold for internal to external use. The thermally broken profiles of the aluminium bifold doors ensure a high level of thermal performance whilst the lightweight nature of aluminium means the doors are effortless to open. 

To create a steel look design we incorporate a bespoke glazing bar design into each bifolding door panel (to your specification) which creates the industrial aesthetic of a steel door in a bifold. All the bifold doors from Sieger are available with glazing bars to create this industrial style aesthetic. 

At the Showroom

There are multiple slim framed bifold doors on show at the newly renovated IQ Glass showroom in Amersham. This includes a 3-metre-tall, 3-track bifolding door installed within the showroom that displays the exceptionally slim profiles. 

Another Sieger Lux Bifold forms part of the new glass façade and uses a high-level solar control glass to create reflective glazing that sits within the bifolds ultra slim frames. 

Bifold doors are often overlooked due to the thicker sightlines than sliding doors for example, but our bifolding door solutions can achieve this minimal design.
