ABOUT THE PRODUCT:
The MB-86 EI is a system of thermally insulated, fire-rated windows, doors and partitions. It is designed to be used for building external fire compartments fitted with operable windows and doors and fixed partitions with a primary fire-rating of EI30, EW30 and EI15, in line with the PN-EN 13501-2 standard. The structure is based on our MB-86N system, meaning that it features high thermal and acoustic insulation, along with excellent water- and airtight parameters.
As such, it combines the advantages of a classic window and door system with the properties of fire compartments in terms of its thermal properties, durability and production technology. The construction not only fulfils all the requirements of the regulations in force and the standards for energy efficiency and environmental protection, but also ensures proper fire safety provision. The system is classified as ‘no fire spread’ (NRO).
