Normen
In Ergänzung der EC 5 »Bemessung und Konstruktion von Holzbauten« soll der HBV genormt werden. In Vorbereitung hierauf arbeiten mehrere Forschungseinrichtungen in Europa zur Zeit an einer Technical Specification.
Eigenschaften des HBV
- große Spannweiten
- geringes Eigengewicht
- guter Feuerwiderstand
- guter Schallschutz
- geringe Schwingungsanfälligkeit
- Vorfertigung möglich
Sound insulation standards and their application are frequently difficult to reconcile.
Not infrequently, the key objective in existing buildings is to harmonise different protection requirements of different users. Practical experience suggests that it is best to establish the sound attenuation level by reference to local building construction regulations.
Where a new component is installed, the recognised rules of the art apply. In existing older buildings this can lead to conflicting objectives which should preferably established and resolved during the planning phase. Where a Principal or Purchaser of an older building requires an enhanced level of sound insulation, this should always be agreed in advance, writing. We recommend use of Supplement 2 to DIN 4109 and the VDI 4100 references values as the basis for decision.
