In-depth Fire Rated Testing

myRENZbox Modula have been fully tested in the extreme conditions at Warrington Fire Research Laboratory. The test includes our products being recessed within a wall and backed into a furnace, with temperatures exceeding 1030 degrees Celsius.

In order to pass the test they need to withhold their integrity and not distort, release any gaps, ignite nor spread a flame. They therefore need to demonstrate they can contain or hold back a fire for 2 hours.

Full details of the test and report are available upon request.
