Wooden Floor - BHA

Sound insulation dry screed PhoneStar - one board one system

Here you can see 10 floor constructional systems with PhoneStar on closed, wooden, beamed ceiling. Those are ordered by installation height of 10 - 70 m, shown with graphics and sound insulation datas.

with inset and filling

BHA BodenHolzAlt (FloorWoodOld)

Output value impact sound L'n,w,R=66 dB

Output value airborne sound R'w,R=49 dB

The figures above are shown with PhoneStar improved efficiency.

The specified panel thickness are calculated without the final covering. 

Please consider the notes at the end of this chapter.

*   To save installation height (approx. 16 mm), the Holzweichfaser is replaced by the Wolf Protection  

     Fleece. Please contact us if necessary.

 

**  Please note the following information for the given sound insulation datas and other technical

    specifications.

 

Note:

If there are high airborne sound insulation datas of the construction and low impact sound pressure levels which are measured in the underneath room, the sound insulation will be better.

(Encouragement by "Normhammerwerk").

Upgrading impact and airborne sound insulation

Further improvements can be achieved through targeted floor constructional systems DHA.
