Phonewell is a footstep soundproofing panel (impact and airborne sound). Its cardboard structure consists of crossed and glued layers filled with pure burnt quartz sand and a heavy loose mass. Only a mass of this kind, combined with lightweight filler material, can ensure such high soundproofing properties. This patented combination is the key to unprecedented living comfort.
