THERM+ H-I – Timber façade

Product Objects Cut

The THERM+ timber curtain wall system provides an approved glazing technology application to structural frames made of any timber based material from 50 mm width. For a sustainable and lasting function the consistent system design assures strict separation between the structural elements and the functional components of aluminium profile and gaskets.

  • Two types of screw fixed aluminium base profiles; with or without profile locator
  • Quick and easy fitting of the base profiles; also suitable for assembly with magazine fed electric screwdrivers
  • No external components penetrate through to the timber frame

The RAICO timber connector TC

The connectors between mullion and transoms on a timber curtain wall must fulfill additional specific requirements. The dead load of the infill units is positioned in front of the timber structure, and the connectors must compen­sate for this torsional effect in addition to wind pressure and suction forces.


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.


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.


Fire 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.


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.
