MB-86N EI Fire-Resistant Windows, Doors and Partitions

Fire-resistant windows and doors with thermal insulation

The MB-86N EI system is a comprehensive solution platform for fire-resistant windows, doors and partition constructions with thermal insulation, designed for the construction of external fire compartmentalization. The system offers fire resistance classes EI30, EW30, EI15, as well as EI60 for doors in accordance with PN-EN 13501-2. Based on the MB-86N platform, it provides excellent thermal and acoustic performance, combining the advantages of traditional window and door systems with specialized fire barrier properties. Three-chamber aluminum profiles with a central insulation chamber between 43 or 42 mm thermal breaks guarantee high energy efficiency. The system is classified as a fire non-spread (NRO) construction and complies with all applicable regulatory requirements.
