The THERM+ mullion-transom curtain wall system using steel combines the advantages of set-on-top construction with those offered by curtain wall systems with integrated screw channel. Additionally, the fixture technique of the steel curtain wall system makes it possible to select from standard steel profiles and the special set-on-top construction guarantees an optimum corrosion protection.
Advantages
- Stepless thermal insulation by means of RAICO Insulating Block Technology
- Total load chain with approved connection, from the welding with the supporting structure and the glass load transmission to the screwing of the pressure profile
- Safe and easy glass load transmission for heavy panes up to 1,500 kg

Perfect corrosion protection thanks to plastic base profile
With its specific material properties, steel offers an extremely rich variety of forms and therefore a diverse range of creative possibilities. The unique patented fixture principle of the THERM+ system has been developed from real-life requirements in order to extend those possibilities further without limiting itself to glazed curtain walling, and at the same time to reach a safe but simple assembly as well as providing maximum protection against corrosion.
moreVariants
Passive house
The standard THERM+ system can easily be upgraded to passive house certified standard with minimal additional components. Passive house projects can therefore be fitted with energy saving glazing in a generous, cost effective way, independent of their supporting projects.
moreStructural 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.
moreFire protection
Minor additions to the standard THERM+ system are all that is needed to construct fire resistant curtain wall in a range of protection classes. The maximum size of 1,920 mm x 3,000 mm glazing panels provides a new dimension in fire protection.
moreBurglar 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.
