Technical data sheet Acoustics & Design Sound-absorbing panel Plettro™ is inspired to the well-known musical accessory used by guitarists, but this geometric shape does not come exclusively from a design choice, and the reference to the musical world is only one of the suggestions. Indeed, the idea of this new product actually comes from this particular shape analysis and its potential acoustic performances, in addition to its notable aesthetic features and suitability for the integration in various architectural contexts. Plettro™ panel is suitable especially for prestigious historic buildings, thanks to its shape (comparable to a triangle), and can be placed in the typical horizontal position, but also adherent to complex vaulted ceilings (barrel, ribbed, cross or pavilion). The modern and curious drawing of these sound absorbers lets Plettro™ be suitable even for contemporary architectural contexts, such as big open workspaces, showrooms, museums and exhibition places. Moreover, Plettro™ panels are developed according to a green and sustainable approach, being completely realized with eco-compatible, recycled and recyclable materials. Pletiro™ shape is well known with the technical name of “Reuleaux Triangle”, and it consists of three curves based on the equilateral triangle, where all the perimetral points are exactly at the in the picture on the right, in which three curves are represented with a dotted line and the perimetral points are in red colour). It's thus a geometry extremely interesting from the surface can give an acoustic regular response to the incident sound wave, as in the circular form happens.

BM CONSTRUCTION SYSTEM The construction system of Plettro™ panels consists of thermo-smoothed and heat-bound PET polyester fibre, totally fire resistant, and an internal perimetral structure made of hot-molded plastic polymers. This solution permits to obtain an assembled panel with a high structural resistance, even if it maintains an extreme lightness if compared to the common and similar panels, realized with wooden or metallic structures. The surface covering is realized with a robust two-way stretch fabric made of fireproof polyester, available in a wide variety of textures and colours...
