Put our over 130 years of experience performing fire tests on building materials, products, and assemblies on your side. Our laboratory experience provides an excellent sense of cause and effect, benefiting you in the design of your products, materials, or assemblies.

Do you need site-specific approvals? Actual construction details are often slightly different from those tested due to cost, timing, availability, and other reasons. With an engineering analysis, we can often show that the as-built design is equal or superior to that which was evaluated and approved. If it's not, we can recommend alternatives to bring the assembly up to code, which is done by following standard fire protection engineering rules and comparing approved designs that are very close in detail. Letters of endorsement from Professional Engineers registered in any U.S. state are available on request.
