Gypsum Tile Backer

WEBTECH® CGF is used as a facer for many feet of gypsum tile backer products. The coated fiberglass mat was developed to help keep moisture out. Testing of the CGF shows it will not support the growth of mold and mildew. The WEBTECH® OPTICoat Technology can be used to deliver superior adhesion and water resistance properties. WEBTECH® CGF has been used for years as a facer to products used in kitchens, showers and baths.

The Atlas Web Technologies Coated Glass Facers that are manufactured for gypsum tile backer products are usually constructed of a glass fiber wet process mat coated with a latex based, highly inorganic filled coating. The glass mat serves as reinforcement for the coating, and also the end product for improved features.

Atlas Web Technologies has printing and coloring capabilities for all CGF products as well as the ability to provide branding through the use of company logos, messages, etc.
