Plura® is an acoustic diffusion panel, manufactured in ABS on an absorbent filling box. Its design has a geometry that reproduces symmetry at a 180º rotation. It consists of a combination of two ellipses in one bent hollow, thus giving it a predominantly round shape with tenuous angles, which is good for diffusion. Plura® is meant to diffuse mid and mid-high frequencies. When using multiple pieces jointly on a continuous area, it improves its sound diffusion efficiency. Amazing diffusion effect can be obtained when used in large rooms. We can make several different aesthetic combination effects by rotating the panels 90º or 180º and positioning them according to one's taste and to the room’s requirements. The shape is the same as the Plura® ABL, which is an absorbent; they can be applied together to obtain different combinations of sound diffusion and absorption. The inner part of this model is made on a composite substance of impregnated mineral fibers and textiles, which gives this product a specific mass and also contributes to its consistence. The external raw material of this panel was selected out of some materials that have the fastest and most specific properties required for a diffuser with these characteristics, however the ABS still has some advantages, namely UV protection, impact resistance and fire resistance M1. The back part consists of a flat surface, which includes the mounting accessories. Its shape adjusts to even surfaces. Using our fastening materials we can apply it on walls and ceilings, “T” type mounting bars for false ceilings as well. This piece is available in various colors, thus allowing an appropriate background for each space. The mounting process is rather easy by simply using the fastening devices that are supplied.
