Alpha Acoustic AcouCeLL – Petalo (6 τεμ.)

Description:
αcouCell-Petalo is a panel made of honeycomb acoustic cell foam.Inspired by nature and the symmetry of flower petals, we created the curved triangular form. It has closed cells that are subsequently opened through partial perforation on both sides, which effectively traps sound and reduces the reverberation time, improving vocal clarity. Its original external appearance resembles, looked at from a distance, as granite relief surface
(some people even simulate it as volcanic).

Acoustic performance:
The sound absorption index (αs) according to ISO 354.2003 per square meter is presented in the diagram on the right. The weighted sound absorption coefficient (αw) according to ISO 11654.1997 can be found in the following table:

Main characteristics:
High sound absorption especially in the mid frequency (human speech), low weight, fiber free, structurally indedent, moisture resistant, washable surface, fire retardant. The acoustic energy enters internally the cells stimulating the membranes of each cell converting this energy to heat.

Dimensions: 53 x 50.8cm
Thickness: 50mm standard
Color: Dark grey standard /White on demand
Packing: Box of 6 pieces.
Fire rating: According to DIN 4102:B1, EN 13501-1 (B, S2 d0)
Water resistance: Provides unaltered and sustained acoustic
performance in wet or humid conditions.

Typical applications:
αcouCell-Petalo can be used in a variety of projects even in spaces with high humidity. They can be attached to the wall or ceiling to form patterns. They are typically installed in home Theaters, Recording & Post Production Studios, Rehearsal Rooms, Conference Rooms, night clubs, bars, offices, meeting rooms, swimming pools, mechanical rooms, restaurants etc.
Bellow you are some panel combination examples:

Installation method:
Due to the light weight and its self- supporting structure of the panels it is very easy to be installed on site.
Step 1: The panels can be installed leaving a gap between one another and form compositions.
Step 2: Once the desired pattern is decided, the positions of the panels on the wall or ceiling should be determined.
Step 3: Then, each piece can be glued with magnetic spray adhesive (ask us for information) or using mechanical fastening with suitable plastic anchors.

Available sound absorbing area:
According to the selected installation method, the available sound absorbing area may be the front, the sides or also the back of the panel. For the 50mm thick standard Petalo panels the front and back side area are 0.19m2 each. The side edges total area is 0.08m2. Therefore, if the panels are e.g. attached to a wall at a distance from each other the available sound absorbing are is 0.27m2 for each panel. The maximum sound absorbing area is achieved if all sides of the panel are visible eg when hang from the ceiling at a distance from walls or other surfaces.
