System Description

The system is the all-rounder among window systems and combines design, cost-efficiency and the familiar AKTOHERM quality.

Straight lined, flush design and slim profile views as well as casement styles with bevel edge allow a very high design potential in virtually any colour.  In addition, the large glazing spectrum from 24 to 66 mm allows the use of special function glass for additional visual and planning benefits.

The quality standard for our profile systems starts in the development stage. That’s why our profile wall thickness are about 2 mm to ensure you receive a high degree of process reliability and sturdy hardware mounting for you. The Euro groove allows all standard hardware in the long term to ensure it can be replaced long term

With the 16 mm hardware groove you can offer your customers unusual and multifaceted applications with low cost implementation. Top insulation ratings paired with outstanding security technology and sound protection with extremely simple processing and lean production costs round off the functionality of the AT 740 SI system.
