Aluminium back-ventilated rainscreen cladding support system
Alu TP GmbH offers a number of brackets and profiles for the aluminium back-ventilated rainscreen cladding support systems. All brackets, known as ATPFix, are available as medium and large elements and are provided with an integrated thermal separation. All products are on stock.
Advantages of the AluTP subsctructre for back-ventilated façades
Due to the huge selection of different products for the substructure, there are almost no limits to the design of a back-ventilated rainscreen cladding support system, which can feature a wide range of cladding materials and material combinations as well as options for visible or concealed mounting.
The ALU TP substructure products for back-ventilated rainscreen cladding support systems always prove to be very cost-efficient. Investors prefer these products for prestigious projects where leasability and profitability are paramount. The cost-efficiency aspects are also reflected in the requirements for sustainable construction.
TBack-ventilated rainscreen façades are very unlikely to be damaged. Even if a cladding material needs to be changed, this can be achieved with minimum disturbance to the overall structure.
By using aluminium rainscreen cladding support systems, eco-political objectives are achieved for both new buildings and redevelopments. The measurable reduction of heating energy minimizes the emission of carbon dioxide, which is considered one of the major ecological burdens.
Recyclability of all individual components
The recyclability of building materials and components is a major factor regarding sustainable building and is increasingly becoming more important. Back/ventilated rainscreen façade guarantees the fraction ability of the components into their individual constituents and allows recycling to occur.
The aluminium back-ventilated rainscreen cladding support systems by ALU TP can be used for different energy requirements with insulation that is calculated individually. Any desired thickness of insulating material can be used for this. High summer temperatures inside are perfectly regulated.
The presence of an air gap and insulation results in sound reduction index performance improvement of up to 14 dB
Protection against moisture and condensation
Due to the structure of the back-ventilated rainscreen façade, the vapour diffusion resistance decreases from the inside to the outside. Any moisture from condensation or accumulated during construction is channelled away through the ventilated space.
The façade is the structural component, which is most likely to be damaged. Due to the constant influence of the weather. Moisture damage and cracks will emerge over the years.
Back-ventilated rainscreen façades belong to the load group III according to DIN 4108-3 and are water resistant. The ventilation space between the insulation and lining (weather-resistance barrier) quickly voids dampness. Hung, ventilated façades can, therefore, be constructed with open, horizontal seams without decreasing the protection against rain.
By applying an aluminium rainscreen support szstem, conventional lightning rods can be omitted and an electromagnetic shielding of the building can be achieved.
Due to the wide choice regarding the system components of back-ventilated rainscreen façades, the fire protection requirements ‘non-inflammable’ and ‘hardly inflammable’ can be met according to country specific building legislation.
Fitting of the ATPFix bracket
It is possible to align the profiles accurately using the punched clamping spring. The ATPFix can compensate unevenness of up to 4 cm. The clamping springs hold the profile in place until it is fixed permanently in its final position with self-tapping screws.
Screwing the ATPFix bracket element with the profiles into the round holes creates a fixed point which non-positively dissipated the weight loads of the cladding into the masonry.
Movement due to thermal longitudinal expansion of the profiles is possible if the self-tapping screws are fixed in the slots. The wind pressure and wind suction loads are also transferred non-positively into the masonry.
Extra care must be taken during installation to ensure that the profiles are only used storey high. Only one fixed point should be provided per profile – otherwise sliding points must be created.
