The UL Product iQ published online by Underwriters Laboratories Inc. (UL) lists gypsum panel products that are classified for fire resistance under category “Gypsum Board (CKNX).” Each UL Design lists the specific manufacturers and products that are suitable for use in the design. The products are identified with a Type designation that ties back to specific board formulations. The UL Type designation appears on the UL label on the product. However, gypsum panel end tapes and product literature do not generally contain the UL Type designation but rather a product name or trademark. The following tables provide a quick and easy reference to identify the specific products, brand names, or trademarks of each gypsum panel manufacturer for each Type designation in the UL Product iQ online directory.
