General Building approval anchoring of windows in concrete and masonry
Component test using AMO-Y 11.5 mm frame screw to attach a glazed plastic door to a structure without lateral supports or spacers in PP 1.6–0.30 aerated concrete masonry. Test report no. 11-002642-PR01 dated 25 May 2012
Individual window installation situation: Plan, calculate and confirm using the ift assembly tool at www.montagetool.de
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). Note the guidelines for planning and executing the installation of windows and house doors (art. no. 5995 000 000). To ensure the fall-proof mounting of windows in line with applicable guidelines and regulations, approved securing systems (e.g. window installation rail W-ABZ) must be used, or approval is required for each individual case.
Fast and tension-free spaced mounting of window and door frames
- Tension-free spaced installation for all frame materials for anchoring in aerated concrete
- Specially for door and window fixing in aerated concrete
- Installation of window and door frames with ∅ 10 mm pre-drilled mounting hole
