Windstopper Extreme

A windproof membrane for exterior walls

Windstopper Extreme is a special type of build board. The board consists of grey cement and limestone filler, reinforced with a specially selected fibre material that can absorb and release moisture without affecting the durability, strength or performance of the board.

Windstopper Extreme has a very low vapour transmission resistance, enabling moisture from inside the building to pass through. 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 Extreme is non-combustible.

When installed according to Swisspearl installation instructions, Windstopper Extreme will function as a temporary facade for up to 12 months. Please note that Windstopper Extreme cannot be used as a permanent facade sheet.
