Resistance and containment

The building material industry's resistance and containment team offers architects, code officials, fire prevention experts and the construction industry certification and customized testing services.

A unique benefit to testing at UL is getting your product Listed in a UL product directory, an invaluable resource used to determine the correct application of a product or system. Product directories contain the names of companies qualified to use a UL Mark on products that comply with UL's requirements.

Architects, authorities having jurisdiction (AHJs), purchasing agents and others turn to UL's product directories to find important information about products bearing the UL Mark. UL's regulatory services department is dedicated to promoting the product directories directly to appropriate officials. Acceptance of the product directories minimizes processing and construction delays.

Having your product Listed in a UL product directory instantly puts you in front of more than 2,500 AHJs and code officials.
