L-wall holders for ventilated rainscreen façades.
The angular L-shaped wall holders FLH AL of the ATK 100 vertical support system made of aluminum are the basis for the vertical level. They are fixed to the building substrate using fischer fixings (such as frame fixings SXRL). To reduce thermal bridges, the wall holders can be installed with additional thermostops made of hard PVC. To enable all common insulation thicknesses and façade offsets, the wall holders are designed in different projection lengths. In order to compensate the thermal expansion of the profiles, the wall holders are used both as fixed points and as sliding points. In addition to the proportional wind loads, the fixed point absorbs the entire dead load of the façade panels and subframe. The sliding point with its slotted holes also ensures that the vertical profile can slide due to thermal expansion. The sliding point is also used to transfer wind loads.
