The S 8000 IQ system allows us to produce entrance doors which are the showpiece of any home. Thanks to the bridges arranged laterally in entrance doors, we can install steel reinforcements. Door threshold frames allow the closed combination of the entrance door frame and threshold. Doors in this system can be opened both inwards and outwards. We can install all available fittings and door closing elements to the entrance door profile. As a filling for doors, we can use not only glass, but also a board with a thickness of up to 46 mm. The door threshold is 20mm high and is also suitable for homes of disabled people. Thanks to the aluminum cap it is hard and the corner-mounted sealing block ensures high tightness.The extremely warm S 9000 profile with a depth of 82.5 mm combines the features and advantages of a central and a thrust seal. This profile has six chambers in the frame as well as in the sash/leaf, and the system of distribution of seals in three planes are a guarantee for perfect thermal insulation. Windows made in this system meet the highest expectations of our customers. The central seal, which is flexible, increases the thermal insulation of the window, and protects the hardware against moisture, which ensures efficient operation of the hardware when opening and closing the window. The heat insulation coefficient of windows in the S 9000 system can be 0.92W/m2K. We can use here triple glazing units with a thickness of 54mm.
