1. INSTALLATION ON CEILING FRAME Open the folded film to its full width. Lift and fasten against the ceiling beams so that there is atleast 20 cm of overlap against the outer wall.

Attach the film to the frame posts. Also attach around windows and doors. If necessary, seal the seams with a type-approved moisture barrier tape.
3. INSTALLATION ON WOODEN FLOOR FRAME Attach the vapour barrier film to the floor beams in the same way as to the ceiling. Ensure that there are overlaps.
4. PENETRATIONS Seal penetrations with type-approved moisture barrier tape.
