Installation instructions
1. Remove old tiles and insulation material. Nails and screws■
that visibly penetrate the interior panelling must be covered
with acoustic insulation panels. If none are visible, DELTA®-
Sd-FLEXX may be laid out directly on top of the interior
panelling.
2. Lay out sheets across the rafters in parallel with the gutter,■
making sure that there is no tension in the space between
the rafters. Hold DELTA®-Sd-FLEXX in place with laths along
the rafters.
3. Make sure that sheets overlap by 10 cm. Seal overlaps■
against draughts with DELTA®-MULTI-BAND.
4. Seal any seams (e.g. gutters, flues, roof windows) against■
draughts with DELTA®-THAN plus laths or with DELTA®-
KOM-BAND. Openings for pipes should be sealed with
DELTA®-FLEXX-BAND.
5. Cut the insulation material to fit the space between the■
rafters (+ 1 cm) and lay it on.
