DensShield Tile Backer is an entirely different product than greenboard. The paper facings of greenboard can wick water, and can delaminate when exposed to moisture, causing tile failure. Greenboard is not recommended for use in extreme high moisture (wet) areas and therefore does not meet the 2006 IRC Section R702.4.2 for backer for wall tile in tub and shower areas. DensShield Tile Backer has a heat-cured acrylic coating over its face mat with face and back mats made of fiberglass instead of paper, and has a proprietary, treated moisture-resistant core. DensShield offers a proven tile backer design that is compliant with more stringent 2006 IRC and IBC codes.
