Spax Air ventilation 9 x 2.8 x 0.4 cm 40 pieces 4.5 mm joint

Moisture is the builder's enemy. This applies in particular to permanent moisture, so-called waterlogging - this is where wood rots first. With SPAX Air 4.5, there is a simple way to separate the boards from the substructure, which ensures better ventilation of the wood and rapid dehumidification. At the same time, the 4 mm thick SPAX Air 4.5 ensures the correct and even spacing between the planks, making installation much easier. In this version of SPAX Air 4.5, the distance between the planks is 4.5 mm. For you, this means: perfect constructive wood protection for a longer service life of your decking.
