CertainTeed has applied advanced technology - used to produce our acclaimed WeatherBoards Fiber Cement Siding - to interior ceramic tile underlayment and backerboard. These products feature a dense, non-porous surface, making them excellent choices for kitchen and bathroom applications where moisture is a fact of life. The surface and edges are also smoother than those of competing products, for easier installation and neater finished jobs.
Backed by 100 years of excellence in service, CertainTeed has developed a complete set of installation instructions for our fiber cement products. Important: It is recommended that local building codes be reviewed. CertainTeed shall not be responsible if any failure to comply with these instructions results in the siding failing to perform the purpose intended.
