Airborne sound insulation
Frequently asked questions (FAQ)
The polyester polyurethane acoustic foams are characterized above all by a
rough, open-pored structure and a firm grip. They are therefore characterised by a slightly higher sound absorption coefficient than polyether foams.
The polyether polyurethane acoustic foams are characterized above all by a soft handle and a very elastic, fine and open-pored structure.
Polyurethane foams (PUR) have an open-pored structure and are therefore used as acoustic foams for sound absorption.
Polyethylene foams (PE) have a closed-cell structure with good thermal insulation properties. PE foams are used for thermal insulation due to their properties and weigh the good compressive strength in the packaging sector.
Basotect? melamine foams are open-pored and at the same time provide good thermal insulation and very good sound absorption and also have very good fire protection properties.
Sound insulation, the acoustic separation of rooms. In sound insulation, the acoustic separation of rooms, against undesired sound from neighbouring rooms or from outside, is the main focus. The propagation of airborne or structure-borne sound is prevented by reflection at the transition between two media.
