G80 - Passive Combined System

State-of-the-art system for windows, doors, and lift-slide doors, with a choice of two or three sealing levels

Thermal insulation Uf
> 0,89 W/(m2K)
Air tightness window

It offers the option of building passive house-compatible window elements, including in colour, in accordance with the ift directive WA-15/2 using standard profiles and standard 2 mm steel stiffening elements. The certified Uf value of 0.89 W/(m²K) confirms the outstanding basic heat insulation properties.

System with rigid central gasket

G80 is the new central gasket system with a stable bar in the window frame. The central gasket bar effectively protects the mechanical parts in the window from external factors. Central gasket systems stand out for their excellent insulation qualities.
 

Outstanding break-in resistance

Even the standard version of the G80 system is one of the safest options around. But the G80 system’s new central domed gasket makes the burglar’s job much harder. Most break-ins start with the window being levered out: the intruder slides a screwdriver between the frame and sash. The sturdy new dome is an effective barrier against this.
 

Perfect for large colour elements

Its outstanding static properties make G80 plus ideally suited for building large elements with acrylcolor surface finishing.
 

Visibly less frame

Significantly narrower than previous frame combinations. In the past, mullion designs often required a width of up to 150 mm and above. Heavy, unattractive bars ruined the window outline and let far less light into the room. Slim sightlines can finally be achieved with the new system, without forgoing ease-of-use and security.
 
 

No compromise

Despite the focus on narrow sightlines, the new sash/mullion profile doesn’t compromise when it comes to statics. Both use a particular steel which, due to its static properties, allows for elements of up to 2.30 m in white and 2.20 m in colour. In combination with STV® bonding technology, element sizes up to 2.50 m in white and 2.40 m in colour are possible.

Optimised geometries

Entire frame geometry was optimised while the profile widths were compressed to a minimum. The designers paid special attention to achieving a balanced relationship between insulating properties and statics, as well as a perfect interplay of components. The symmetrical effect of the narrow single mullion also adds to the flexibility of use in window construction.

Optimised heat insulation

Developing a system with the best heat insulation properties does not happen by accident, but rather as a result of focused development work. Our success proves us right. Numerous calculations have produced outstanding heat insulation values. Right from the beginning, the goal of development was to achieve a heat insulation value of Uf – 0.92 W/m²K for the standard combination with steel, making the system suitable for use in passive houses. This was accomplished through the sum of the innovative system design details.
