AeroSound SF & ESF– Acoustic Underlay

AeroSound SF (silent floor) underlay is a cross linked closed cell polyolefin foam and ESF is flexible elastomeric rubber foam with medium density underlay for all floating floor applications.

AeroSound SF and ESF underlay is designed to reduce impact of sound in floating floor systems, it is designed to use in both commercial and residential buildings, such as apartments, hotels, hospitals, schools and universities to reduce the sound transmission level to below levels. Usual application is to separate concrete base floor from final screed or screed from final finishing, used in corners (between wall and floor) for the same purpose.
