32. Proper Installation of the External Window Cill: Especially beware of installing the window cills impervious to rain. The window cill has to be connected to the window, the embrasure and the façade in a manner resistant to driving rain. Especially in the area of prefab houses there have been large damages in the past due to erroneous installation of external window cills; driving rain was able to penetrate the structure and dampen the insulation and/or the load bearing structure (of plywood and HOLZRIEGEL), which resulted in sustained damage. If a driving rain resistant connection of the external window cill can not be guaranteed, a second insulating layer underneath the window cill has to be created. It also has to be raised on both sides (vertically) by at least approx. 80 mm. Butyl plaster and/or systems featuring special seals have proven themselves as driving rainproof connections along with the connector caps by AFB. External cills in façades Flashing connections (e.g. window cills) have to be planned so thermally induced movements are decoupled from the façade in order to be able to absorb the thermal movements and so changes in length (through differences in temperature) do not create damages of the façade. As a result, aluminium window cills in façades may henceforth only be equipped with L-header and according insulation material joints or with sliding headers (which are able to absorb the lengthwise expansions due to temperature sufficiently). Exposed concrete header: Sliding header: If external sunlight protection with guide rails mounted to the windows exist (blinds, louvers, …), beware that the guide rails always drain into the “tray” of the window cill! For detailed information pertaining to the installation of window cills in WDVS and plastered façades please refer to the “Window Cill Guidelines” by the Austrian Window Cill Association.

33. Guidelines for the Use of Glazing Blocks in KATZBECK Systems The use of glazing blocks has to follow the below guidelines in order to be able to deflect the dead load of the insulating glass properly into the frame and into the load bearing hinges for opening leafs. These guidelines for the use of glazing blocks must also be observed fully for glazing performed at the construction site, on the one hand to prevent any glass breakage (stress cracks in fixed elements), on the other hand to counteract the “hanging” of a leaf (for opening leafs). 1 1 2 2 2 2 1 1 2 2 2 2 2 1 1 2 2 2 2 1 2 1 1 1 1 1 Drehflügel Turning sash Drehkippflügel Tilt-and-Turn sash Kippflügel Tilting sash Klappflügel Folding sash 1 1 2 2 2 2 2 2 2 2 1 1 1 1 1 1x 1x 1 Schwingflügel Turning sash Fixverglasung Fixed glazing Fixverglasung mit Fixed glazing Scheibengewicht with glass weight >100 kg >100 kg 2 2 2 2 2 2 2 2 1 1x 2 = Tragklötze Support blocks = Tragklötze Support blocks minimal thickness geringerer Dicke = Distanzklötze Spacing blocks 2 2 2 2 1 1 1 1 Hebeschiebe Lifting-Sliding / PAS PPS window/door Fenster/Türe In addition, spacing wedges have to be assembled in the area of safety locking parts and secured accordingly (glued).
