We can find solutions for any combination and develop your multifunctional board together with you. This reduces your stocks and your space requirements since you only need to produce a single door type.
Our multifunctional boards cover several important requirements at the same time, depending on material combination:
- Sound insulation
- Fire resistance EI30 – Ei90
- Smoke tightness
- Heat insulation and
- Burglary protection RC3
Example: The H-Flachs multi-function board
Sound Core/Fire Core
- The H-Flachs Sound Core/Fire Core has outstanding sound insulation properties
- Light weight
- Fire-resistance A2 S1; d0 in accordance with EN 13501-1
- Heat conductivity coefficient ʎ = 0.057 W/mK
- For EI30, EI60 and EI90 fire protection solutions
- H-Flachs Sound Core/Fire Core is free of formaldehyde
- Smoke protection
