REGUPOL sonus curve 6

For Floating Floor Constructions

Formerly SonusWave SW36, REGUPOL sonus curve 6 is our thinnest version in the series. It is suitable for constructions with limited floor heights that still require an impact sound insulation.

Our 6mm (1/4") thick REGUPOL sonus curve 6 underlayment is engineered, manufactured, and tested to reduce the transmission of impact sound generated by footfall noise. Durable, versatile, and cost-effective are the main characteristics to describe this dimpled flooring underlayment. Various thicknesses let you design many different floor constructions to reduce impact and airborne sound transmission within building structures. REGUPOL sonus curve 6 is perfectly suited for spaces with limited floor height in commercial and residential buildings underneath hardwood, concrete, screed, and floating floor systems.
