There may not seemingly be anything particularly glamourous about vinyl tile/plank flooring underlay, however, truth be told, there are aspects of good underlay that will do a great job in making your floor perfect. Like sound. This 3/64" (1 mm) underlay has a high sound rating: STC 67 / IIC 71 / Delta 21. It also features no VOC emissions; anti-crush technology for excellent footfall performance and long life; superior vapour barrier; seal guard for best edge seal; exceeds uniform building codes; excellent over radiant heated floors; it's mould and mildew resistant; and can be used over concrete and wood substrates above or below grade.
