Skilled in the deve­lop­ment of innova­tive ope­ning mecha­nisms and specialised in every method of facade ope­ning, Gretsch­-Unitas has been a com­pe­tent partner in facade con­struc­tion for many years. GU experts take pro­ject-related special parts deve­loped exclusively for individual pro­jects as innova­tive enginee­ring work and combine them with ele­ments from the tried-and-tested GU range. With hard­ware for Pro­je­c­ting Top-Hung, Par­allel-Pro­je­c­ting, Horizontal-Pivot or Turn-Only win­dows, as well as special designs based on individual cust­omer speci­fica­tions, it is pos­sible to satisfy demands for new methods of ope­ning and window shapes with unique aes­thetic quali­ties. The range of services extends from technical plan­ning and design through to pro­duc­tion of the special parts and handling of pro­jects toge­ther with cust­o­mers all over the world.

Par­allel-Pro­je­c­ting hard­ware

The special solu­tion for sashes which weigh up to 400 kg. that open up to 250 mm and the sashes are up to 5,000 mm. Par­allel-Pro­je­c­ting win­dows can be created with a compre­hensive range of GU stays for all frame mate­rials, such as wood, PVC and aluminium.

Hard­ware for Turn-Only win­dows

Today's facades, with their floor-to-ceiling win­dows, pre­sent a challenge for stan­dard hard­ware. In order to meet these enhanced require­ments, Gretsch­-Unitas deve­lops special Turn-Only hinges, either in stai­nless steel or in a concealed ver­sion, which carry sash weights up to 350 kg.

Pro­je­c­ting Top-Hung hard­ware

This hard­ware range offers a number of different Pro­je­c­ting Top-Hung stays with an ope­ning angle from 20° to 50°. Sashes can be made up to a height of 2,500 mm. Pro­je­c­ting Top-Hung win­dows can be made with GU stays for all frame mate­rials, such as timber, PVC and aluminium.
