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

The AeroSound® SF and ESF – Acoustic Floor Underlay is an acoustic insulation solution for various applications like bringing more acoustic comfort, designed to avoid structural noise such as noise caused due to walking, jumping, bouncing or pulling. Also, AeroSound® Recycled Rubber Acoustic Floor Underlay (RSF) is designed to reduce impact sound in flooring systems and to increase the acoustic comfort. It is made of recycled rubber particles, the rubber structure provides high acoustic, and mechanical performance.
