DESCRIPTION TECHNICAL DRAWINGS

WOODWALL® 0428 is a construction finishing material with acoustic absorbing properties. 12.8
Following an ecological philosophy, JOCAVI® has developed this line of acoustic treatment
materials, which are made exclusively from recycled pressed wood fibers (HMDF) and 240 4mm 1.5
coconut fibers. The wood plate is provided separately from the coconut fiber layer and can 28mm
be assembled together during the installation. 15mm
This compound is made of coconut fiber (as an energy absorbent material) and perforated GROOVES AND 20mm
panels made of pressed wood fibers, made of strictly 100% recycled materials has an PERFORATION
excellent technical performance. The coconut fiber is a natural, renewable and very light DETAILS WEIGHT
vegetal material. It has high porosity (95% of pores), which translates into an extremely high 3.0 Kg
absorption of sound energy. COCONUT FIBRES
The good behavior of the recycled wood fibers, associated with the coconut fiber's micro- NOT INCLUDED
porous absorbent properties, makes it a natural first-class combination in terms of
acoustic solutions. MODELS AND SIZES
The WOODWALL® 0428 is ideal to install in auditoriums, conference rooms, sport
pavilions, business spaces, restaurants and bars, etc... It can be installed with wood or MODELS HEIGHT WIDTH DEPTH

• JOCAVI® accepts no responsibility for any printing errors. Specifications can be modified without prior notice, if technical or commercial reasons so require.
• 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.
• Due to its natural origin, wood-based products will always present natural imperfections inherent to the organic nature. And for similar reasons, they will also present traces of old-age in the course of time.
• Wood and Fabric products are highly susceptible to change its appearance with humidity and temperature. Close attention must be paid to the storage conditions and the acclimatization before, during and after the installation.
• 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.
• Despite all the standard sizes of all products, this model can be customised upon previous consultation. Sizes may vary slightly due to their production method and some inherent raw-materials characteristics.
