Wall claddings for ships, boats, yachts & co.
With the use of large-sized Metawell® panels the number of joints in the walls can be reduced. Using common fastening profiles, the panels can be mounted fast and flexible, e.g. tongue & groove.
Metawell® Aluflex is the ideal panel for parapet linings and curved parts. It can easily be bent in one direction while staying rigid in the other direction. Furthermore it has a better attenuation characteristic than a solid aluminium sheet.
Installation of wall elements
Tongue & groove
Panels with a thickness of 10 mm are particularly suited for butt joints with tongue & groove systems. A simple slitting cutter is used to mill groove into the middle of the corrugation. Then, a flat aluminium profile in a groove-matching size is stuck into the corrugation. After that the second Metawell® panel, which shows the same groove on the long panel side, is buttjointed.
The decisive advantage with the Metawell® tongue & groove system is provided by the remaining corrugation. Thanks to the 0.3 mm thick aluminium sheet used for the corrugation, which has high yield strength, the remaining corrugation parts stabilize the cover panels in the area of the groove and at the same time work as elastic spring elements. This connection levels out certain tolerances of angle drifts and allows for a tight fit of the profile. If needed the aluminium profile can additionally be fixed with the help of an elastic bond system (e.g. a moisture curing one-component system).
Hook systems are ideal for the concealed attachment of Metawell® wall linings in vessels. Support profiles are fixed to the body structure and levelled.
The wall ele- ments are mounted onto the profiles with hooks.
These hooks can be fixed to the panel back with blind rivets. The rivet locks in the space between the panel‘s two cover sheets with the effect that the visible side of the panel shows no optical impairment.
Hat profile system
With the help of hat profiles all kinds of walls can be quickly assembled while leaving the desired flexibility with regard to design and shape.
Tolerances may be evened out when adjusting the panels and profiles on the spot. The hat profile system shown is suitable for all Metawell® panels on condition that Metawell® Aluflex is additionally stuffed in order to guarantee a sufficient clamping strength.
With this system a cover profile is pinched onto the profile that protects the construction against vandalism. It can be taken off with an appropriate tool if, in case of damage, single panels have to be exchanged.
A special advantage of Metawell® panels fixed with a hat profile, is the simple way to form corners.
Metawell® panels with cover sheets of 0.8 mm thick- ness, that are milled on their back, can be used as corner elements. Depending on the direction of the folding, inner or outer corners can be formed.
Since the folding is done by hand, the corners can be adjusted at site. By milling the back of the panel different folding radii (depending on the milling geometry) can be realized. Thus it is possible to level out angle tolerances of the construction almost automatically.
As purely metallic sandwich panel, Metawell® has a low insulation effect, allowing a heat and fire insulation that is largely tailored to the place of use, as it clearly separates the “wall cladding“ and “insulation“ functions. Usually working with floating insulation, the insulation is inserted between structure and Metawell® panels.
