Product Certification
Having your product fire tested and certified is often required for building code compliance. To become certified, a product test report must be issued by an accredited test laboratory.
Over the course of our 25-year history, Guardian has tested and certified thousands of products. Our internationally accredited lab is approved to test to UL, ASTM, NFPA, CSA, and ULC standards for timed fire endurance, flame spread, safety, and efficiency.
We also understand that the listing and labeling process can be intimidating or confusing for many of our clients, especially those new to fire testing. That’s why in addition to our technical expertise, we strive to provide helpful, personalized service from start to finish of the certification process.

- Building products, including fire door assemblies, adhesives, floor/ceilings, and expansion joints
