A non-combustible, breathable sheeting board with a fire rating tested up to 120 minutes. The board consists of grey cement and limestone filler, reinforced with a specially selected fibre material that can absorb and release moisture without affecting durability, strength or performance.

Cembrit Windstopper Extreme Has a very low vapour transmission resistance, enabling moisture from inside the building to pass through. This means that insulation can be placed directly against the inner side of the board. When installed according to Cembrit instructions, Windstopper Extreme will function as a temporary facade for up to 12 months. The lightweight 4.5 mm-thick version can be scored unsnapped making for quick dust free on site cutting. It is ideal for temporary weather sealing of buildings awaiting the completion of external elements.

The board is highly resistant towards both rot and fungal growth and can with stand considerable fluctuations in weather and climate conditions.
