Subframe system made from high quality aluminum with closed overspan for visible fixing of large-format façade panels, e.g. made of fibre cement (FCB), aluminum composite panels (ACM) or high pressure laminate (HPL).
In conjunction with an additional rail system also suitable for concealed fastening of natural stone, back fastended panel materials and terracotta/clay tiles.
The ALKAPO subframe system is comprised of vertical carrier box rails, U-shaped wall brackets and optional accessories. According to their thermal load and demand – the wall brackets are made of aluminum or stainless steel. According to the static engineering demands, we can choose between the box rails ALKAPO 275 and ALKAPO 350.
The cladding elements are fastened visibly to the box rails using screws or rivets.
The wall brackets are fixed directly to the concrete slabs. The box rails are connected to the wall brackets using screws or rivets. When doing this, sliding points accept horizontal (wind) loads and fixed points accept horizontal and vertical loads (dead load). Constraint-free installation is achieved at the sliding points in vertical longitudinal holes. One fixed point is allocated for each box channel.
Thermostop elements are available as thermal dividers to minimise thermal bridging.
Protrusions of up to 180 mm with aluminum U brackets and up to 300 mm with stainless steel U brackets.
