Now available in Canada, Johns Manville (JM) GoBoard® LT is extremely durable and up to 85 per cent lighter than traditional cement boards. The premium tile backer board offers a variety of performance benefits aimed at reducing installation time and eliminating extra steps for installers. It is available in two thicknesses to provide superior performance and meet the needs of a variety of projects. GoBoard® LT 6 mm (¼ in.) is ideal for floors and countertop applications, while the 13-mm (½-in.) board is best-suited for walls, showers, and ceilings.
Advanced technology ensures JM GoBoard® LT has built-in waterproofing. Installers only need to seal board joints and fastener locations for a waterproofed-tile assembly. When installed with GoBoard® Sealant, installers can apply tiles the same day and grout the next in a typical shower installation. JM GoBoard® LT can be quickly cut right where it is installed with a utility knife. It is lighter than traditional cement board, decreasing the time it takes to move the product to and around sites. This premium tile backer board is manufactured for durability. It will not crumble or disintegrate during installation and will withstand superior performance long after installation.
