Aqua-Tough™ Underlayment Panels

FIBEROCK Aqua-Tough underlayment is a unique, fiber-reinforced gypsum product that represents a new era in substrate performance for wet or dry areas. It provides a smooth, uniform surface that is an excellent substrate for a variety of floor coverings. It is engineered to meet water-, mold-, and indentation-resistance needs under resilient flooring, ceramic tile, carpeting, hardwood flooring, and laminate flooring. This versatile interior underlayment has a uniform, water-resistant composition that helps prevent the problems typically associated with wood based underlayments, and is lighter weight and easier to cut than fiber-cement panels.

It is environmentally friendly, made from 95-percent recycled materials, earning it Green Cross Certification from Scientific Certification Systems.

Tested by Tile Council of North America (ASTM C627-Robinson Floor Test), the underlayment meets requirements for residential and light commercial use (as defined by TCNA). It also includes a 20-year warranty against buckling, warping, delamination, cracking, and splitting by fasteners.
