Cembrit Windstopper Extreme
Cembrit Windstopper Extreme is a special type of build board that features a windproof membrane for exterior walls. 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.
Cembrit 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 Cembrit Windstopper Extreme is non-combustible.
When installed according to Cembrit installation instructions, Cembrit Windstopper Extreme will function as a temporary facade for up to 12 months. Please note that Cembrit Windstopper Extreme cannot be used as a permanent facade sheet in accordance to the guidelines provided by Cembrit on Cembrit.com
