FIRE REACTION
Class 1.
FIELDS
OF APPLICATION
Pavit-One must be installed
before flooring in order
to improve footfall
sound-insulation. Thanks
to its sound-proofing characteristics
and to its easy
installation, it is used in
any kind of construction
(houses, offices, hospitals,
trade centres, etc.). As
footfall noise is concerned,
Pavit-One has an excellent
sound-proofing
performance giving better
results than what the
law provides for.
INSTALLATION
Pavit-One must be installed
directly over the rough
floor, its extremities must
cover up and the seams
must be fixed by using the
pre-glued self-adhesive
band. Always use AKUSTIK
BORDER perimeter
band.
The installation of WALL
BAND is also recommended
to interrupt the acoustic
bridges between the
rigid structures.
