Windstopper Basic has a very low vapour transmission resistance, enabling moisture from inside the building to pass through. The unique manufacturing process does not include compressing resulting in a naturally rough surface. In consequence, insulation can be placed directly against the inner side of the board. 

The board is powerfully resistant towards both rot and fungal growth and can withstand considerable fluctuations in weather and climate conditions. 

Adding to this, the Windstopper Basic is non-combustible. When installed according to installation instructions, Windstopper Basic will function as a temporary facade for up to 6 months.
