Folding Thermal Insulating Door System for high comfort & maximal transparency.
FD 4600 is a brand new Bi-Folding door system, offering extremely high performance and impressive, out of competition, technical characteristics.
The desire to create living spaces filled with daylight was never so feasible. This high performance system offers this advantage, as well as a minimal design, high insulation and functionality with hardware that have specifically been designed for folding systems.
Suitable for many different typologies, having the greatest advantage of corner opening without any column. This unique feature ensures maximum transparency and easy opening, whilst another practical feature is that one leaf can act as an opening door without interrupting the other folding leafs.
FD 4600 is available in multiple threshold options in order to perfectly match all comfort and aesthetic requirements. The low threshold option offers a rise of only 24 mm (ramp) giving easy access to people with special needs and allowing maximum convenience for high-traffic areas.
Specially designed rolling hinges, sliding smoothly on the bottom rail, ensure quietly and easily operation of the system.
