best wood WALL 140 Plaster base board for exterior use

WALL 140 is a pressure-resistant, plasterable wood fibre insulation board for installation on full-surface substrates such as solid wood and masonry in exterior wall areas.

Advantages:

Excellent thermal conductivity value
Good heat protection in summer and optimal thermal insulation in winter
Improves sound insulation: wood-fibre insulation boards are very good sound insulators, the higher the raw density the better the sound-insulating effect
Hydrophobic throughout
Open to diffusion and therefore moisture-regulating
Easy installation - secured by our processing guidelines ETICS
Hardly any waste due to the fact that the wood fibre insulation boards can be used on both sides
Completely recyclable
