MB-78EI Fire-Doors

Domex fire-rated doors are built to protect what matters most. Delivering powerful fire and smoke insulation, these doors are constructed with a robust 3-chamber profile and a 70mm installation depth, engineered to resist and endure under the most demanding conditions. Three EPDM gaskets ensure an airtight, smoke-resistant seal across every edge, while a thermal transmittance of Ud = 0.85 W/(m²K) means these doors perform just as impressively on energy efficiency as they do on safety — giving you lasting protection and peace of mind.
