Subframe system made from high quality aluminum for visible or concealed fastening of large-format cladding panels, e.g. made of fiber cement, aluminum composite material (ACM) or high pressure laminate (HPL).
In conjunction with special rails or rail systems, also suitable for visible fastening of terracotta/clay tiles and back-fastening of natural stone and several panel materials.
The ALWI T1 subframe system is comprised of vertical L shaped and T shaped aluminum rails, wall brackets and optional accessories. According to their thermal load and requirements, the wall brackets are made of aluminum or stainless steel.
The cladding elements are fastened visibly to the rails using screws or rivets or are adhered concealed to the rails, screwed on as concealed sidings or fastened with a system rail.
The wall brackets are fastened through a sheathing or a rigid insulation to studs using screws. The wall brackets can optionally be fitted with an assembly aide to simplify working with them, which makes fastening and holding possible for the vertical rail.
The T and L 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 support rail.
Thermostop elements are available as thermal dividers to minimise thermal bridging.
Protrusions of up to 320 mm with aluminum Flex L brackets and up to
400 mm with stainless steel L brackets.
