ESSENCE FD 77

When making an insulated folding door we had to strike the perfect balance; respect the
requirements of extra large openings by creating an extended variety of solutions that
combine deft design with indisputable quality in all the functional elements. The result is a
solid and handsome system that will run smoothly for years to come.

We combined design excellence with unparalleled quality in functional elements. We developed a wide range of such solutions to meet the demands of very large openings.

ATTENTION TO DETAIL

UNOBSTRUCTED TRANSIT
Open passage. With its low thresholds application, with a visible height of just 3mm and 7mm, ESSENCE FD77 is an ideal solution for people with physical challenges and children. Move freely.

EXPANSIVE OPENINGS
Imagine openings that reach 3500mm. You are free to create them. The meticulously studied reinforcements ensure the system’s prime static strength even against extreme weather.

GHOST GLAZING GASKETS
The appliance of Ghost glazing gaskets minimizes the visible facet and renders the gaskets practically invisible. Once more, aesthetic prevails and functionality is not compromised.

CONCEALED WATER DRAINAGE SYSTEM
Υοu never lower the eyes. But we had to provide, just in case. The system that covers threshold water drainage is another feature that upgrades the construction both aesthetically and functionally.
