Custom Building Products has added an uncoupling mat to its line of RedGard products.
Designed for installations using polymer-modified thin set mortars, the uncoupling mat is an environmentally-friendly crack isolation, waterproofing and vapor management membrane for tile, porcelain and natural stone installations over most substrates, including oriented strand board, plywood and concrete, the company says.
Featuring heat-welded fleece on top and bottom, the product is said to provide crack-isolation performance by locking mortar onto the mat at every point of contact for a strong mechanical bond.
No mechanical fasteners are required. The mat is available nationally in 1 x 30 m and 1 x 5 m rolls. A 30 m roll replaces up to 21 sheets of ¼ in. backer board.
