- The terrace deck is constructed at ground level and creates a level circumferential terrain edge.
- A distance of at least 20 mm between the boards and raised, fixed components must always be maintained.
- The ground level deck can be created with a closed joint as long as the compulsory construction height is min. 161 mm, a compulsory min. 2 % gradient is adhered to and circumferential ventilation grilles or other constructional measures are ensured in order to provide an adequate under ventilation or back ventilation.
- Only implement a level floorboard structure with a 5 mm in conjunction with a ventilation
- Use of the ventilation grid (also with „placed-on“ deck or in the event of a closed gap) in order to improve the air circulation beneath the terrace and to increase the service life of the entire deck.
