Break-in protection resistance class 2 according to DIN V ENV 1627. Expert opinion of ift Rosenheim no. 255/29923 dated 21 November 2005
Test of suitability for fastening a window to a brick masonry structure by ift Rosenheim. Test report no. 105 30599 dated 10 July 2006
It is important to check that the components are correctly installed for the specific construction conditions (e.g. weight of window casement, surface properties, hole pattern in the brick).
Pre-drilling of window frame (10 mm). Drill perforated and hollow blocks with a rotary drill (without impact mechanism). No pre-drilling is necessary in aerated concrete; Amo III screw can be screwed in directly. Align window frames using alignment clamps or Amo Bag.
Screw length = frame width + gap + screw-in depth.
Installation guidelines/RAL Quality Assurance Association:
The fixture must safely transfer all standard forces affecting the window to the structure. This means the total load must be calculated from e.g. the window load, wind load and working load (see DIN 1055). The currently applicable building regulations stipulate that buildings and their components must be planned in such a way that they do not endanger human life and health or pose a risk to public safety. Attachment of the windows must also comply with this criterion. We recommend anchors 51, 52, 53, 55.1 and 55.2 for this application.
Window walls according to former DIN 18056 standard:
This standard applied to window walls with an area of at least 9 m2 and a minimum side length of 200 cm, comprising a support structure (frame, jambs, crossbars) with infill (e.g. glazing). This standard does not apply to walls and glass blocks. We recommend anchors with technical approval for this application
