Aluminium noise insulation panels are the second most popular type of absorbing panels.
ALUMET panels are a further popular market solution affording noise protection.
Our offer spans three versions of ALUMET panels:
- Alumet 1 – single-sided absorbing
- Alumet 2 – double-sided insulating
- Alumet 3 – double-sided absorbing
The Alumet 1 acoustic absorbing panel is made of two profiled aluminum sheets, including the front perforated one, Alumet 2 is made of two profiled non-perforated aluminum sheets, Alumet 3 is made of two profiled perforated aluminum sheets, mounted on two special profiles: upper and lower, which have specially shaped sockets to stabilize acoustic layers inside the panel and are profiled in a way that allows them to be connected in the so-called “tongue and groove”. The color of the panel is determined by the Ordering Party using the RAL palette. Alumet aluminum panels are equipped with side seals that stabilize the panels in HEB/HEA 160 poles.
The modularity of the system allows you to combine panels with other varieties, e.g. Green Wall, wooden or transparent panels. Thanks to the low weight of the panels, their assembly (inserting between previously installed poles) can be done manually without the need to use a crane or HDS. The Alumet 2 aluminum acoustic panel is used as a reflective panel.
