Innovative vapour barrier with humidity-variable SD value for roof renovations. For indoor as well as outdoor installation.
Airtight roof renovation with DELTA®-NOVAFLEXX: Inserted into the compartment from the outside and guided over the rafters. Installed from the inside under the rafters.
DELTA®-NOVAFLEXX can be installed quickly, safely and inexpensively, thanks to the robust and tear-resistant special fleece.
The new surface with halftone printing supports precise and fast processing. The processor is always facing the printed coating side.
At a roof conversion from the inside:
DELTA®-NOVAFLEXX can be applied parallel or across the rafters and is fixed linearly to the side of the rafters with pressure battens (for example trellis battens). Tackle clips or broad-headed pins can be used as assembly aids. When overlapping, the membrane is glued with DELTA®-MULTI-BAND. On smooth surfaces such as gable walls, purlins, chimneys, etc., DELTA®-NOVAFLEXX is connected airtight with DELTA®-TIXX / -TIXX VDR On rough surfaces, the connection is made with DELTA®-LIQUIXX or the DELTA®-KOM-BAND and pressure strips. Corners or cables can be sealed with DELTA®-FLEXX BAND FG 80 / 150 or DELTA®-FLEXX BAND F 100.
In case of a covering/roof renovation from the outside:
First, remove the roofing and the old insulation. In case of nails or screws protruding from the inner lining, insert a thin, covering insulation board. In all other cases, apply DELTA®-NOVAFLEXX directly on the inner lining: roll out parallel to the eaves or from ridge to eave over the rafters and try to apply tension-free into the rafter fields. Fix along the rafters with linear pressure (for example trellis battens). The membrane overlapping must be 10 cm.
In connection areas try to connect as airtight as possible with the DELTA® system accessories and battens.
Then cut the insulation to the width of the rafter field according to the manufacturer's instructions and insert it.
