DIFFUSION-OPEN AIR BARRIER PROPERTIES

AREA OF APPLICATION

Building paper that is a barrier to air, but that is open to vapour diffusion.
It therefore allows the controlled passing of humidity, enabling the creation of a breathing construction.
Specially suited in combination with insulation of the natural fibre flax.
Re-enforced three layer building paper with a plastic net between the two outside paper layers
to withstand unwished cuts because of physical tension/weight.
Easy handling and installation. Simply cut with sissors to the required size.
Product is not a moisture shield.

INSTALLATION INSTRUCTIONS

Please observe the following rules during installation:

1. Attach the paper to the framework by staples every 400 mm
2. Use overlap of 200 mm and / or tape the seams
3. First cover the roof-area and after that the walls
4. Paper has to be installed with care and in case of failures or cuts it has to be replaced.
