ULK KIT

Technical Characteristics

The Ulk kit has been created to meet the need for Top-Hung and Bottom-Hung openings which have considerable weight and size.
Thanks to the Ulk kit, windows can be manufactured with sashes weighing up to 250 kg with Top-Hung opening and up to 300 kg with external Bottom-Hung opening (smoke vents).
The Ulk kit has been specifically designed for 17 mm door/frame stack systems, which is the sash/frame distance of all the main systems used for curtain walls.
The Ulk kit is composed of several components, all made of stainless steel: a pair of hinges, a pair of arms and a pair of adjustment devices for adjusting the sash height when Ulk is applied on Top-Hung windows.
The Ulk kit is ideal for large openings with sashes of considerable weight, for this reason it is advisable to use suitable automations for opening and closing the sash.
Top-Hung windows can be manually operated if the sash weighs less than 100 kg, but always in combination with limitation arms.
In case of Bottom-Hung openings (smoke vents) the opening must always be automated.
The maximum permitted sash opening in both Top-Hung and Bottom-Hung windows is 300 mm.
