Mounting in Hard Segments of ETICS

For securing growing aids elements on insulation, there are several possibilities, one of them are special spacing systems with rigid foam bodies. Such rigid foam bodies are not part of the FassadenGrün assortment and thus not deliverable, but with those fixation ashlars,  the FassadenGrün- supporting cable holder WM 12XX6  or anchor AS 12XX6 (for wooden trellises) can be combined. The warm insulating compound system "may not be 'ready" here yet, because the necessary hard bodies are to be inserted before plastering. This page explains the installation of rigid foam bodies and holders and thus complements the product sheet WM 12XX6 and AS 12XX6. A special case is the use of cross-holder WM 12227 in hard bodies with aluminium plates, see if necessary the link.


Greening Systems and foam body walls must be planned well in advance in façade work, the system supplier of ETICS have helpful parts in stock and can advise if necessary. Also walls with flame-proof insulation such as rigid polyurethane foam, foam glass or cork are best suited. Behind the insulating layer, a supporting surface such as concrete, natural stone, solid bricks, hollow masonry or aerated concrete is required.

Assembly process of WM 12XX6 in think ETICS with pre-installed hard foam segments

Installation of the pressure body

The round or square rigid segments (in the sketch above red) insulation are built in the 'soft' part of Styrofoam and mineral wool before plaster and paint are applied. In the photo one of the hard foam squares is seen as a future assembly point of a cross bracket. Important: Please observe the installation instructions for the respective EWIS system provider.

Mark and Plastering

Centered in each installed hard bodies is placed a marking nail, then follows plastering and painting. This is usually done by mechanized spraying with colored plaster. Removing with the trowel requires an increased effort due to the overhanging marking nails.

Hard foam mounting plate (cuboid)

Search and remove marks

After completion of the cleaning and repainting the marking studs must be removed. The area is possibly color-coded so that it can again be found quickly for drilling.

Marking in the mounting plate


Drilling is performed with an extra-long hammer bit or until 16 cm insulation thickness with a percussion drill bit. Drilling depth in the supporting base is approximately 10-14 cm. It is absolutely vertical and horizontal drilling, the drilling dust is collected or sucked out with a hand pump. For details see sheet for Drilling.

Hollow masonry

In hollow masonry extra long anchor sleeves are also to be used- SD 16130, bore then mandatory 16 mm and 140 mm deep. The perforated sleeves will be cut to a smaller size, so that they can be introduced better and without sliding in too deep.

Inserting a sieve sleeve

Pressing in composite mortar

This should proceed according to the instruction sheets of the composite mortar. For very thick insulation, if necessary, set up extension tube on the mixing tube of the cartridge (please inquire). Abundantly fill with mortar. Also in the area of ​​the hard foam body, later the shaft should be surrounded by mortar on all sides as possible.

Pressing in composite mortar

Insert and position threaded shaft

While rotating push the threaded shaft in the abundantly filled with composite mortar hole, and secure (with match sticks) if necessary from below against sagging during setting. Extracted swelling mortar removed with rags. After plugging, the shaft should be accurate as far as the selected distance from wall (s. WM 12XX6 or AS 12XX6) looking out over the wall outer edge.

adjusting the shaft length

Small adhesive pressing ring

After the setting time indicated on the mortar cartridge then one can begin the assembly. For an optimal sealing plaster, should the plaster surface be reasonably smooth or prepared (polished). Then there is first the small adhesive press ring pushed onto the shaft and pressed tightly to the plaster surface.

Standard-attachment in insulation

Cover disc

Then, the stainless steel support disc follows, along with laminated-foam gasket and also glued to the rear face is a big black adhesive pressing ring.

Flange nut

After the flange nut is screwed and tightened with a wrench against the cover until the threaded rod is tightly seated and a further turning with medium manual force is not possible. Structurally remains an 'open gap' between cover plate and wall of about 0.5 mm gap width.

Two flat nuts

Subsequently, two flat nuts can be screwed on. The first is tightened as a lock nut against the flange nut. For this is a second ring wrench is used. The second flat nut remains further out on the threaded stem.

Crosshead or trellis cross-beam fastened

Then with WM 12XX6 the crosshead is screwed tightly, adjusted with the second flat nut as locknut, first without grub screw. The further assembly is then completed according to the respective cable system or as described for heavy kits. In AS 12XX6 the trellis spar is secured.
