Mould (fungul) and dust free construction


By this method it is possible make construction is free of mould growth and same time save energy because the need of air condition is less. By providing a separate ventilated air gap behind the interior trim panel, which is sucked up by a vacuum, the interior air remains fresh, dust-free and mold-free in all situations, including when windows are opened. Particularly useful structure in public spaces such as schools and kindergartens.
