The chamber system with two aluminum walls offers the terrace screw a good hold and achieves a high static load. Aluminum is almost indestructible and very dimensionally stable. The rails can easily be shortened with a hacksaw.

Please ensure good ventilation and pre-drill the floorboards and substructure. The swelling and shrinking of wood can cause problems when combined with an aluminum substructure if the terrace is not well ventilated and the wood and aluminum have not been pre-drilled.
