6. Installation of the vapour retarding and air tight layer<br />
Once the metal studs are securely located, VARIO KM or VARIO KM Duplex UV can be<br />
applied as a vapour retardant, air tight layer. VARIO accessories, such as VARIO DS,<br />
an adhesive sealing compound, and VARIO ProTape, an adhesive tape, are used to fix<br />
the membrane to the studs, floor and ceiling. The construction is only air tight if<br />
VARIO KM / KM Duplex UV are bonded well to the floor and ceiling. Each membrane<br />
seam should overlap by a least 10 cm (Picture 1).<br />
Applying single-sided VARIO KB1 tape to all membrane seams ensures a reliable, tight<br />
seal. Overlapping the seams by at least 10 cm, and the tape’s powerful bonding<br />
strength avoids leaks in the system (Picture 2).<br />
Cable penetrations are made airtight with VARIO MultiTape SL. VARIO Stos or Mangete<br />
Passelec are also ideal for sealing off various other installations (Picture 3).<br />
7. Cutting and fixing the facing<br />
The facing material should be cut to a length of the floor to ceiling height minus 1 cm.<br />
Hold the board flush to the ceiling and screw it directly to the studs (Picture 4), at<br />
30 cm intervals, leaving a minimum of 1 cm perimeter from the edge of the board.<br />
