ESSENCE FD77

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.

THE DESIGN
THE DESIGN

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.

EXTRA FEATURES

HEAVY DUTY ROLLER HINGES

High strength roller hinges that offer stability, safety and smooth movement even in the widest openings. Ideal for long-term operation, without problems such as sash hanging. Their special design prevents lifting of the sash and, accordingly, intrusions.

SPECIALLY DESIGNED MINIMAL HANDLE AND PULL HANDLE

Aesthetics and functionality are combined in the specially designed handle by ELVIAL and the intermediate pull handles with or without integrated hinge for easy locking, depending on the direction of opening.

SINGLE OR DOUBLE DOOR HANDLE

Handles are so sophisticated that render a unique style to any architectural design. Function and appearance are in perfect harmony.

MULTIPLE LOCKING POINTS

This aluminum system was designed to let ample light in and allow its users to enjoy it. Light and users only. So we designed it to ensure high anti-burglar protection, with 3 locking points on the door.

THE OPTIONS

FOLDING DOORS

ANGULAR FOLDING DOORS

7 sashes + 1 door with an inward opening

FOLDING DOORS

Folding doors are very popular in modern architectural designs. The ability to fully open and fold into a small size allows them to create large, open surfaces. This makes their operation excellent in both residential and professional premises. Natural airflow and an increase in natural light are also few of their many advantages.
4 sashes + 3 sashes with an outward opening

THE TECHNOLOGY

An infinite visual that prompots phantastic voyages and light that elevates. ESSENCE FD77 allows you to enjoy the best of ample openings. The challenges of thermal insulation, security and watertightness are not an issue, thanks to ELVIAL technologies.

THERMAL INSULATION

An expansive opening and an interior of equal standards. This aluminium system was created to be the boundary, the line of defence of the interior against the challenges presented by the weather elements. We fitted it accordingly.

  • UP TO 32MM INSULATING BARS (en)

    Insulating bars with 25% glass reinforcement of 32mm in sash and 24mm in frames and thresholds are applied, offering high thermal insulation levels and extra rigidity.

  • CO-EXTRUDED GASKET

    Co-extruded gasket is used in the perimetrical area of the frame, improving energy performance.

THE ADVANCED SEALING SYSTEM

Another challenge for aluminium systems designated for extra large openings has been tackled thanks to sealing technologies that have been tested and proven to be not just adequate but superefficient.

OPTIMAL 2-LEVEL WATERPROOFING

Optimal 2-level waterproofing with specially designed EPDM and co-extruded gaskets.

EPDM GASKET CORNERS

EPDM gasket corners ensure maximum sealing, even at extreme weather conditions.

EPDM END CAPS AND EXTENSIONS FOR GASKETS

Τhe joining of the sashes is no longer a weak point. We have it sealed using EPDM end caps and gasket extensions than ensure continuity in the perimetrical waterproofing.

OPTIMIZED WATERTIGHTNESS

Q-LON in the perimetrical area of the frame, with the use of heavy duty rollers.

WATERTIGHT AND SUPER CLEAN

Perimetrical socket channel for the glazing bead, with an elevation difference from the outer side of the sash, which prevents water entrapment.

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.

DURABILITY FOR A LIFE TIME

With ESSENCE FD77 the weather is reduced to a scenery of the stories that shape your life. You have just upgraded your living.

SMOOTHER ROLLING

Stainless steel rail with improved design & reinforced thickness, which ensures the impeccable functionality of the construction even at demanding glazing loads.

EFFICIENT PROTECTION

New generation joint corners with side caps, in all moving parts, which lead the two-component glue along the joint point and completely cover the chambers.

MAXIMUM STRENGTH

There are various reinforcements available in this system designed to match the wind pressure requirement you will prescribe.

MULTIPLE LOCKING POINTS

This aluminium system was designed to let ample light in and allow its users to enjoy it. Light and users only. So we designed it to ensure high anti-burglar protection, with 3 locking points on the door.
