Can I groove into a fire door to simulate a panelled design?
Only if there is suitable test evidence for the door blank and if there is, the precise specifications are followed. The thickness of the door is crucial to its stability when subject to fire conditions. The timber on the side of the fire becomes dehydrated, which leads to the door distorting in towards the fire. The thinner the door, the quicker this happens - and to a greater extent. Grooving into areas of the door will leave localised weak spots and the door will not perform as expected.
