Applications: frame structures of insulated pitched roofs, walls, ceilings, and 
interior insulation. Installed on the warm side of the insulation with the smooth
surface facing it.

It is recommended to leave a 1 cm air gap between the vapor barrier and the interior
finish. “ROCKWOOL® vapor barriers for roofs, walls, and ceilings” reduce heat loss,
ensure comfortable humidity levels in rooms, and extend the life of the entire structure.

Structures: frame structures of insulated pitched roofs, walls, ceilings, internal
insulation

### Insulation of a floor with wooden joists

Floor joists are installed at intervals of 0.6 or 1 m. LIGHT BATTS SCANDIC stone
wool insulation boards are typically laid on boards or panels secured to the cranial
beams, or on boards or steel wire fastened to the beams from below. The insulation
must be protected from water vapor, which migrates toward the colder room. To achieve
this, a layer of ROCKWOOL vapor barrier is installed over the insulation (on the
inside of the warm room). To ensure better vapor impermeability, the vapor barrier
sheets should be overlapped by 10–15 cm. The edges of the vapor barrier sheets are
extended 10 cm above the insulation surface and secured to the wall with a baseboard.
Floorboards and flooring are laid on the wooden joists.
