Mounting in Hard Segments of ETICS

There are several possibilities for securing trellis elements on insulation. One is: special spacing systems with rigid foam bodies. Such rigid foam bodies are not part of the FassadenGrün product line 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 section 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 the link if necessary.

Pre-conditions

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

Drilling

Drilling is performed with an extra-long hammer drill or up to 16 cm insulation thickness also with a percussion drill. Drilling depth in the supporting base is approximately 10-14 cm. It is essential to drill vertically and horizontally; the drilling dust will then be collected or vacuumed out with a hand pump. For details, see section on drilling.

Drilling work in insulation

Hollow masonry

In hollow masonry, additional perforated sleeves (extra long) are to be used- SD 16130, the bore size then necessarily 16 mm and 140 mm deep. The bundle of perforated sleeves is then cut away except for a bit remaining, so that they can be more easily inserted, yet without sliding in too deep.

Inserting a sieve sleeve

Pressing in composite mortar

Proceed according to the instruction sheets for composite mortar. If the insulation is very thick, place the extension tube on the mixing tube of the cartridge (please inquire). Fill abundantly with mortar. Also in the area of ​​the mounting element (hard foam body), the shaft should be later surrounded as much as possible by mortar on all sides.

Pressing in composite mortar

Insert and position threaded shaft

Turn the threaded shaft into the borehole (now richly filled with composite mortar) and, if necessary, secure it with match sticks against sagging from below while setting. Remove swelling mortar with a cloth. After insertion, the shaft should show over the wall's outer edge exactly as far as the selected wall distance (see WM 12XX6 or AS 12XX6). 

adjusting the shaft length

Small adhesive pressing ring

After following the setting/drying time indicated on the mortar cartridge, one can begin the assembly. For an optimal sealing plaster, the plaster surface should be more or less even, smooth, prepared (sanded). The small adhesive press ring is first 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 the large black adhesive press ring glued to the back. 

Flange nut

Then the flange nut is screwed on and tightened with an open-end wrench against the cover until the threaded rod is taut and further rotation with medium manual force is not possible. Structurally, an "open joint" (approx. 0.5 mm gap width) remains between the cover plate and the wall.

Two flat nuts

Two flat nuts can now be screwed on. The first is tightened as a lock nut (counter nut) against the flange nut, using a second open-end wrench or ring spanner. The second flat nut remains further out on the threaded shaft.

Fastening the crosshead or trellis bar (cross-beam)

Then, with WM 12XX6, the crosshead is tightly screwed on, fixed with the second flat nut as lock nut, initially  without the grub screw. The further assembly is then carried out according to the specifications of the respective cable system or as described for Heavy Kits. With AS 12XX6, the trellis bar is attached/secured.
