Wall holder as fixed point with a projection length of 93 mm.
The Pi-wall holder of the subframe system ATK SystemOne made of aluminum is the basis for a façade subframe. It is fastened to the building substrate using fischer fixings. To reduce thermal bridges, thermostops made of hard-PVC can be attached to back of the wall holders. In order to enable all common insulation thicknesses and façade offsets, the wall holders are designed and manufactured in different projection lengths. To allow the thermal expansion of the profiles, the wall holders are used both as fixed and sliding points. The fixed point absorbs the entire dead loads of the façade panels and subframe system in addition to the proportional wind loads.
