The Espoo lift and escalator group, holding five LPCB certificates for lift landing doors — 1418a for the KES800 non-insulated, 1418b for the glazed KES800, 1418c for the insulated KES800, and 1418d covering the KES602 and KES202. A lift landing door is a compartment closure that has to work as a door thousands of times a year and as a fire barrier once, and the insulated and non-insulated variants are certified separately because they answer different parts of a fire strategy. Finland’s only fire-door certificate holder in the RedBook.
