Kolpak modular panels and components have been certified by independent testing laboratories for compliance with code requirements for flame spread, smoke development, toxicity and sanitation. Final approval may be dependent upon application and local codes. We can supply the backup data you need to get approval from most local, state and federal agencies.

Underwriters Laboratories Inc.
Kolpak Panels are tested and evaluated by UL for flame spread and smoke developed ratings. The panels are listed under URL file R8160. The ratings are displayed on the UL label affixed to the panels.
Kolpak door panel assemblies are also tested and evaluated by UL for various electrical requirements. The door panel assembly is listed under UL file E46140 and the listing mark appears on Kolpak door panel assemblies.

NSF
Kolpak walk-ins carry the NSF mark to certify they meet the requirements of NSF Standard #7

Factory Mutual System
The Factory Mutual report states, "...fire tests show the Kolpak minimum 26 gauge steel-faced wall and ceiling urethane insulated panels of four inch maximum thickness meet Factory Mutual Standard 4880 approval requirements." They are approved for use as insulated core wall and ceiling panels (on walls, no greater than 30 feet in height) without a need for sprinkler protection in and of themselves. The end use of the panel would determine if sprinklers are required.

Canadian Standards Association
"The Kolpak door panel assembly is listed by the Canadian Standards Association as certified." It is certified under Report Number LR67755-1. CSA construction must be requested.
Toxicity and Ignition Properties Tests
Independent testing laboratories ran both ignition and toxicity tests on Kolpak panels. Both test results were well above normal requirements. The toxicity tests also demonstrate that, "when tested as specified, Kolpak panels generated products of combustion which were no more toxic than those expected from wood."
