In conjunction with special rails or rail systems also suitable for visible fastening of terracotta/clay tiles and ceramics and for back-fastening of natural stone and several panel materials.
The HAPRO subframe system is comprised of vertical aluminum hat channels and Z girts. They are fastened through a sheathing or a rigid insulation to studs using screws.
The cladding is fastened visibly to the vertical rails using screws or rivets.
Optionally, the vertical support rails can be provided with sliding point perforations to accommodate possible linear expansions.
