PROPERTIES FOR DIFFUSION-OPEN AIR BARRIER PAPER AND TAPE

DESCRIPTION OF THE VAPOUR CONTROL LAYER (VCL)

A special building paper that is a barrier to air, but open to vapour diffusion.
It 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 strong net between the two outside paper layers
to withstand unwished cuts and increased ability to handle physical tension and 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. Tape the building paper joints or overlap at least 20cm and staple on the framework at 40cm intervals.
  2. First cover the ceiling-area with building paper and after that cover the walls.
  3. Building paper has to be installed with care and in case of failures or cuts it must be repaired or replaced.
