Marathon Dual® acoustic, fast track floor prep system for Cushion Vinyl & Click LVT
Marathon Dual® enables a simple and economical, dry floor preparation for residential use, suitable for all loose laid floor coverings. It is quicker than screed, better than hardboard and smoothes almost anything.
Marathon Dual® consists out of an MDF top board with a soft board base board. The MDF top boards but up practically seamless together and overlap all the joints of the bottom boards, simply levelling out unevenness up to 2 mm. This creates the most perfect surface for floating Cushion Vinyl, Click LVT´s and even self-adhesive LVT´s.
Marathon Dual® performs a high imprint resistance against for instance chair legs, high heels and other sharp objects resting permanently on the floor surface. The appearance of your flooring is not disrupted by permanent imprints, as is often the case with soft underlays underneath vinyl floor coverings.
Marathon Dual® is tested under ISO-10140-3:2010, for its impact noise reducing properties. In combination with 3 mm cushion vinyl it achieves a reduction of 23 dB ΔLw, with 3 mm self-adhesive LVT´s 22 dB ΔLw and with 4 mm Click LVT´s 21 dB ΔLw. These great improvements were obtained on a concrete floor with an attached screed*.
* In a floating screed situation, the noise reduction of the composed top floor always depends on the impact noise reduction of floating screed system in place.
