TILE BACKER, WALL BOARD AND UNDERLAYMENT
GreenE-Board™ is extremely water resistant. It will not swell, delaminate, warp, or disintegrate when exposed to a wet environment. Remarkably, GreenE-Board™ is also water vapor permeable. This allows GreenE-Board™ to be used as a wall-board in construction where breathable walls are specified. GreenE-Board™ can be used on walls or floors.
