Wavin AS+
Technical Manual
3.3. Sound-insulating performance
The excellent sound protection properties of Wavin AS+
are primarily attributed to its thick-walled design as well as
special molecular structure and the high density of ~1.9 g/
cm
3
of the material used to make the pipes and fittings. This
property enables Wavin AS+ to absorb airborne sound as well
as structureborne sound.
Studies conducted at the Fraunhofer Institut für Bauphysik
(Fraunhofer Institute for Building Physics), Stuttgart, on Wavin
AS+ attest to its excellent sound absorption properties.
