Bifold Doors FAQs
Q1: How do bifold doors work?
Bifold doors are made of several glass panels known as leaves that slide on a track. The panels fold in a concertina style and slide smoothly along the doorframe until they stack neatly against the wall.
Q2: What is the maximum size available for these doors?
Our bifold doors can reach a maximum width of 6200mm and a height of 2400mm, accommodating up to seven panels. When opened, the frame occupies only 10% of the space.
Q3: Are bifold doors better than sliding doors?
Bifold doors offer a 90% clear opening by folding away, whereas sliding doors typically overlap, leaving a fixed panel in place. The choice depends on whether you prioritize a full wide-open span (Bifold) or large unobstructed glass views when closed (Sliding).
Q4: Are these doors energy efficient?
Yes. The aluminum frames feature a thermal break to prevent cold transfer, and we offer various glazing options including double or triple-pane Low-E glass to optimize thermal performance.
Q5: What security features are included?
They come equipped with a multi-point locking system along the track, high-security cylinder locks, robust hinges, and internal glazing beads that prevent glass removal from the outside.
Q6: Can I customize the color and finish?
Absolutely. You can choose from over 200 RAL colors, including wood grain finishes, powder coating, and dual-color options to match both your interior and exterior decor.
