PAINTING
The COMPOCEL AL FR Sandwich Panel has been certified with different types of powder or liquid paint to suit various stylistic, aesthetic and environmental requirements.
MAINTAINANCE
The panel’s user manual indicates the conditions under which the material must be stored and preserved optimally. Among the most important factors affecting panel storage are: storage temperature, handling, exposure to light and weather. Particular attention must be paid to the presence of protective films that may be difficult to remove when subjected to atmospheric agents or after prolonged storage. The panel is easy to clean and degrease, but the use of acidic substances or abrasive components is not recommended as they could compromise its aesthetic qualities.
SUSTAINABILITY
The COMPOCEL AL panel is 95% recyclable as it consists of 95% aluminium, which can be melted down and reused several times.
