Panels perforated on visible side (acoustic fleece on rear)

The product MAKROPOR® L meets the standards of quality specified by the Association of Industrial Metal Ceiling Manufacturers (TAIM). It consists of electrolytic galvanized sheet steel; the standard version is coated with a white coloured powder coating. Versions are also possible in all RAL and NCS colours.
Thanks to the large selection of perforations as well as the wide variety of formats (lengths: 601 mm to 3200 mm widths: 250 mm to 960 mm) it is possible to adapt the product perfectly to on-site conditions.
The thermal conductivity of the metal material ensures the product is eminently suitable for use in cooling ceiling systems.
