DoP
Certificate type
A wind and weather proof protection for exterior walls.
Application
For exterior wall protection.
Description
A non-combustible, wind and weather proof protection for exterior walls. Windstopper Basic has low transmission resistance which enables moisture from buildings to pass through. The manufacturing process does not include compressing which results in a rough surface in which insulation can be placed directly against the inner side of the board.
The board is highly resistant towards both rot and fungal growth and can withstand considerable fluctuations in weather and climate conditions.
Features and benefits:
- Will function as a temporary facade for up to six months.
- consists of natural materials.
- Can be fixed to both wood and steel.
- Class A2 fire rating to EN 13501-1.
- Low maintenance.
- Weather resistant.
