Point: 2.7 Are the requirements of OIB Guideline 4 for doors also applicable to French doors?

Yes, the requirements of OIB Guideline 4 for doors with regard to safety in use and accessibility also apply mutatis mutandis to other accessible openings (e.g. French doors). In addition to point 2.7, this also applies to all other relevant points of OIB Guideline 4. The regulatory area concerning construction products (e.g. performance requirements for doors, windows, French windows) remains unaffected.
