MIDREW company offers internal fire-resistant wooden doors with the Halspan system, with fire resistance ratings of EI 30 and EI 60. The individual designations represent E – fire integrity (in minutes) and I – fire insulation, also expressed in minutes. Fire resistance is an extremely important characteristic and a criterion to consider when choosing building joinery.
Constancy of performance certificate
We have the National Certificate of Constancy of Performance covered by the national technical assessment ITB-KOT-2018/0407 ed.1.

Our doors are characterised by the quality of workmanship,
details and fire protection conditions met
There is an increasing interest on the market in the use of historical buildings for the provision of services, e.g. hotels and public services, but in order to meet the requirements, they must meet the conditions of fire protection, otherwise, they cannot be approved for use.
The vast majority of historical buildings must comply with fire protection requirements in order to be authorised to provide commercial services. Fire-resistant joinery of the EI30 and EI60 resistance classes that we offer is one of those elements.
