The CORALREEF® is a 3D controlled dispersion acoustic diffusion panel. It is made of
high-density polystyrene and its finishing membrane provides it with the intended 60 12
acoustic qualities.
Its angular appearance gives dynamics to any space and provides a decorative effect MODELS AND SIZES

The calculation basis was the theoretical numerical sequence ratio of the primitive root,
CORALREEF® | DIFFUSION PANEL thus providing excellent results of sound diffusion in all directions. The depth factor is
logarithmically varied, and it is, therefore, a three-dimension omnidirectional reflection
panel. Due to its quite sinuous shape with deep recesses, as well as the raw material it is
made of, this product also has a considerable associated absorption coefficient.
Is the top model of ATP® diffusers set.

IMPORTANT NOTICES

44 • JOCAVI® accepts no responsibility for any printing errors. Specifications can be modified without prior notice, if technical or commercial reasons so require.
• RAL© is an international independent colour standard system partner for industry, trade, architecture and design. Should be consulted before placing any order.

• The colours shown on this catalogue are only a reference and an illustration of the products finishing. The colours shown are not binding because brightness, contrast and colour balance may vary due to the printing process.

• Colours may vary due to raw-material suppliers' changes and some differences may occur in tonal range.
• Typical Indoor Comfort Standards state a temperature range of 20ºC - 27ºC (68ºF - 81ºF), and a relative humidity of less than 60%. These would be considered as normal operational levels of JOCAVI® products' range.

• Sizes may vary slightly due to their production method and some inherent raw-materials characteristics.
