Windows & Doors

  • Concept System® 86-HI is a highly insulated system for windows and doors, which meets the highest requirements concerning safety and stability. The system’s insulation concept not only ensures the extreme stability and elevated water- and air tightness, but also makes it perfectly suitable for triple glass applications.

    The overall insulation value (Uf) of the system’s HI+ variant goes down to 1.0 W/m²K. The frame/ vent section with 117 mm visible width has a Uf value of 1.4 W/m²K, making it one of the most energyefficient systems available. CS 86 even achieved the Swiss Minergie® and Minergie-P® component label. With regard to safety, CS 86-HI can comply with burglar resistance classes 2 and 3, offering an ultimate level of security.

    (1) The Uf-value measures the heat flow. The lower the Uf-value, the better the thermal insulation of the frame.
    (2) The sound reduction index (Rw) measures the capacity of the sound reduction performance of the frame.
    (3) The air tightness test measures the volume of the air that would pass through a closed window at a certain air pressure.
    (4) The water tightness testing involves applying a uniform water spray at increasing air pressure until water penetrates the window.
    (5) The wind load resistance is a measure of the profile’s structural strength and is tested by applying increasing levels of air pressure to simulate the wind force. There are up to five levels of wind resistance (1 to 5) and three direction classes (A,B,C). The higher the number, the better the performance.
    (6) The burglar resistance is tested by statistical and dynamic loads, as well as by simulated attempts to break in using specified tools.
