The Impactodan‑5 acoustic underlay from Danosa is a flexible, foamed PE sheet with a closed-cell structure for effective impact sound reduction (> 20 dB with a prefabricated floor panel). It impresses with its very low thickness while providing high insulation performance, making it ideal for floor renovations, floating floors, or cold floors.
Manufactured in Spain with 5 % recycled content.
Ready for shipment within 24 hours after payment.
