Flat Cumaru substructure 21x90mm

Cumaru has a particularly high resistance to wood-destroying fungi and is therefore also suitable for structurally demanding solutions where a low construction height is required. As a substructure, Cumaru impresses with good dimensional stability, its resistance class 1 according to the DIN standard. The perfect substructure for wooden decking that needs to last a particularly long time and at the same time requires a flat structure.
