AT 740 SI-D

Based on the high quality standards of our customers, the system was tested with one million opening cycles and thanks to the innovative composite technology counters the bi-metal effect.

The AT 740 SI-D system offers over 100 frame/leaf combinations ranging from two-sided leaf concealing to inward opening, all the way to click filling or the appealing shadow-free version. The range of styles and design options allow you to add design accents, in virtually any colour.

In addition, with the system you can equip the door with up to four seal levels depending on your needs. You determine U value based on the customer’s request. The use of roller hinges in aluminium or stainless steel as well as screw-mountable and concealed hinges complete the range of variations. The quality standard for our profile systems starts in the development stage. That’s why our profile wall thicknesses are 2 mm to ensure a high level of process reliability in production. To ensure sturdy hardware mounting, the wall thickness is even increased to 3 mm in this area. This detail is beneficial for burglar resistance and durability.
