In addition to selecting and planning a facade, we recommend to pay attention for a professional installation. One should always take into consideration that the quality of the product can only be reflected in the final result when the installation is performed properly. We therefore recommend noting the following aspects for the best possible installation:
A successful façade installation already starts with the proper scaffold position. DIN 4420-1 specifies a maximum spacing of 0.3 m between the scaffolding (fall-protection gap) and the building structure. If the scaffolding is positioned with this spacing when the carcass is built, the spacing will generally not be sufficient later to install a rear-ventilated façade, including insulation. In order to avoid increasing cost and time exposure, we recommend to consider the space requirements in advance. The space between the carcass and the scaffold can be increased with the help of scaffolding enlargement or an additional interior fall protection guard rail.
The static calculation is the foundation for the proper positioning and the distances of the subconstruction. The static calculation takes into account the dead weight, wind suction and wind pressure, along with the resistance to wind loads according to DIN 1055-4. It also determines the number of required anchoring elements and attachment points in dependence of the material of the load bearing wall. A sufficient number of sliding points must be taken into account to allow the subconstruction to absorb dimensional changes caused by temperature fluctuations. This means that the vertical load bearing profiles must be attached with a fixed point at approximately 3/4 of the height, and with sliding points otherwise.
Attaching the facade cladding
Generally need the fastener distances to be chosen in accordance with static requirements and local construction codes. For HPL panels should be the edge distance at least 25 mm. Here as well, sliding and fixed points are needed so that the panel material can expand or draw tight as climatic conditions change. The fixed points on each panel should be approximately arranged along the centerline and should be predrilled 0.5-1 mm larger than the screw or rivet diameter. The pre-drilled diameter should be 3-4 mm larger for the sliding points. The gaps between the panels are important for the material expansion and should generally be 8 mm. However, this dimension can also be changed depending on the panel size.
Vertical substructure with L- and T- profiles. Visible attachment with painted rivets or screws according to the surface material.
Vertical substructure with L- and T- profiles. Invisible installation of cladding only approved with building authorities adhesives.
Vertical substructure with L- and T- profiles. The screws are hidden by siding. Produces a special look and can be executed without horizontal expansion joints.
Vertical substructure with L and horizontal agra-tread profiles. The plate material is hung and fixed with the undercut anchors attached to the back of the UK.
