functional doors guide

What are fire doors? Fire doors can prevent fire from spreading rapidly and protect the entrance and interior of the house from fire. As fireproof seals, they must be self-locking to ensure optimal protection.

What are smoke control doors? A smoke control door is a self-closing door that can reliably prevent smoke from spreading in a separate room. They must be installed as interior or apartment entrance doors with a smoke protection function required by the building regulations.

Good sound insulation is essential for well-being, healthy sleep, and life because noise causes stress and, in the worst case, disease. Soundproof doors increase the quality of life significantly with the soundproofing effect.

The different climate classes describe the durability of the interior doors and apartment entrance doors, also known as the warping rigidity. Attention must be paid to this if the climate on both sides of the interior door is different.
