An inexpensive way to attach wooden trellis on insulation from 10 cm layer thickness. For rigid foam, polystyrene ("Styrofoam"), soft wood fiber boards, etc. Not suitable for mineral wool and other flaky or bulked insulating materials. Without cutting the facade. Does not form a thermal bridge! However, only for low to medium loads. Wall distance 20 mm, the actual distance from the wall is calculated from the wall gap and the sum of the screwed cross-sections and can be up to 60 mm for lath thicknesses of approx. 20/20 mm. Please also use the tips for the step sequence in planning and execution of wooden trellis and for optimal trellis attachment.


Recommended Tools

For pre-drilling (8-12 mm) hammer drill bit HB 44444. Alternatively, concrete drill bit, inexpensive stone drill bit, or universal drill bit. For the second drilling, hammer drill bit HB 16160.



With a drill d = 8 - 12 mm, just pre-drill a bit (Fig. 02) to pierce the plaster layer, then drill with a drill d = 16 mm approx. 15 - 25 mm deep and without hammer blow to create a straight guide for the dowel shaft. For soft wood fiber boards and Heraklith-boards: Here, the 16 mm hole is made to a depth of approx. 90 mm. Then grasp the point holder with a 13 mm open-end wrench on the flange nut and carefully screw in (palms with working glove - Fig. 03) until the thread engages and it is aligned vertically and horizontally. Then continue to screw in the point holder, constantly checking the vertical and horizontal alignment and, if necessary, correcting by pressing on the side. It is turned until the resistance increases significantly and the foam gasket is pressed together (Fig. 04). The large cover disc must have quasi contact with the grain of the plaster through the seal in order to act as a pressure disc. Subsequently, the respective trellis spar is mounted between the two spring washers and flat nuts. If the spar is too thick, attach without spring washers, or countersink the borehole.
