APA Facade Systems Bi-Fold door system offers a wide variety of solutions to suit any project requirement.
Known for its versatility, our bi-fold door is available with up to 14 sashes, opening internally or externally, substantially increasing natural light and airflow for commercial and residential developments.
The accordion-style design allows the user to fold up all sashes neatly against the wall when opened, revealing unobstructed panoramic views.
This thermally enhanced door system comes with superior thermal performance with transmissions as low as 1.1 W/m²K. This is thanks to its thermally efficient polyamide core (24mm to 44mm), and the possibility of installing high-performance glass units up to 45mm.
The bi-fold system is available with a single and dual colour finish to match Qualicoat (RAL colours).
The excellent design of this system allows you to insert the bottom of the frame into the pavement, leaving the threshold completely hidden. The wheels and rollers are also concealed when the door is in the closed position providing a high-quality, aesthetically pleasing finish.
