Innovation down to the smallest detail

An essential feature of the THERM+ aluminum facades are the innovative T-connectors. Your technique has been optimized to the smallest detail and offers a wealth of benefits.


Structural Glazing

The THERM+ Structural Glazing SG2 curtain wall systems feature the most intricate glazing technique. A narrow silicone joint is the only visible line between the insulation glass panes. Retention of the internal pane is enabled easily, quickly and securely with the use of SG glazing toggles. By utilising the SG insulating block, curtain walls achieve outstanding thermal insulation values.


Burglar resistance

All THERM+ curtain wall variants may be made burglar resistant in accordance with the German resistance categories RC2 and RC3 by adding a few supplementary system components. Providing maximum creative possibilities, all system widths and all types of pressure plates with clip on cover caps, visible screw fixings, as well as flat pressure profile plates (in RC2) may be used.
