REGUPOL sound and drain
For outdoor applications
The impact sound insulation material REGUPOL sound and drain has the CE marking and has been tested to DIN EN ISO standards. It provides acoustic insulation, membrane protection and drainage for a wide range of balcony and terrace constructions in one product.


How to know about REGUPOL sound and drain
Especially in urban residential projects, hotels, and apartment buildings, outdoor areas often generate disruptive footfall and usage noises. Professional impact sound insulation, such as REGUPOL sound and drain, minimizes sound transmission to living and sleeping areas below and significantly enhances living comfort. This is particularly relevant for rooftop terraces, rooftop bars, pergolas, and heavily used outdoor areas.
REGUPOL sound and drain 22 can be used under concrete slabs, ceramic tiles, wooden planks, and elevated support structures. The 15 mm thick impact sound insulation membrane is suitable for terraces, balconies, roof gardens, and pergolas, as well as for various substructures in new construction and renovation projects.
Depending on the installation, the product range reduces impact sound by up to ∆Lw ≥ 37 dB, thereby significantly improving acoustic comfort. At the same time, the elastic protective layer shields the waterproofing from mechanical stress and ensures reliable water drainage. This makes REGUPOL sound and drain ideal for high-traffic outdoor areas in residential, hotel, and commercial construction.
REGUPOL sound and drain is an impact sound insulation system for outdoor use, specifically developed for balconies, roof terraces, loggias, and accessible roofs. The system combines effective impact sound insulation with drainage functionality and protection for the roof waterproofing. Especially in modern residential and mixed-use buildings, this solution ensures greater quiet in the rooms below.
REGUPOL sound and drain
REGUPOL sound and drain products are monitored by internal quality control and third-party inspections subject to the European Technical Assessment ETA-18/0239, which guarantees reliable planning within the European Economic Area
REGUPOL sound and drain 22 has a dynamic stiffness value of ≤ 21 MN/m³ and provides an impact sound reduction between ∆Lw ≥ 28 dB and ∆Lw ≥ 37 dB.
In compliance with ETA 18/0239, REGUPOL sound and drain 22 shows ozone, oxidation, hydrolysis and weather resistance. It serves as a protective layer to prevent damage to the roof sealing and has been developed with good drainage properties. For balconies and pergolas, REGUPOL sound and drain 22 can be used in combination with Schöck Isokorb® XT.
REGUPOL sound and drain 22 can be installed under fine chippings with concrete tiles but should be checked for stability on-site prior to installation due to the possibility of different mixtures of fine stone chippings that can have different load bearing capacities. To increase stability, pressure resistant thermal insulation ≥ 300kPa can be used. REGUPOL sound and drain 22 is compatible with various roof sealings containing PVC but needs to be approved in each individual case.
