A closed, jointless megawood® deck with megawood® cover strips offers numerous advantages. Apart from a sophisticated appearance, the closed form of the deck prevents losing small pieces. The accurately fitting natural rubber cover strips prevent growth of plants from below, and dirt penetration below the deck is also considerably reduced. Constructing this megawood® deck variant requires more effort in order to ensure sufficient ventilation from below and behind the terrace deck. Closed decks are different from open decks in structure and in execution. The basic condition is an overall structure on stilts with full surrounding ventilation. For this structure, the new FIX STEP system provides the option to install various height configurations of your terrace easily.
