About this product

Impactodan

Impactodan is a cross-linked polyethylene foam sheet whose closed-cell structure provides exceptional physical and mechanical properties. It is used for the acoustic insulation of impact (deck) noise in buildings, decoupling a floating screed from the structural floor. It offers high fatigue resistance and easy installation; its use is guaranteed by DIT No. 439 (439R/22) from the Spanish building-science institute 'Eduardo Torroja'.

Available in two thicknesses — Impactodan 5 and Impactodan 10 — differing in impact-noise improvement and airborne insulation (pick the variant in the selector).

Used for airborne and impact sound insulation in floor slabs between different users in residential buildings, for sound insulation when renovating floors in dwellings, and to complement floating-floor insulation across low, medium and high frequencies in commercial premises.
