Noise insulation

HPG phon-modul® 35 dB / 40 dB

Keep calm and comfort.

Particularly high demands are placed on the roof window as the interface between outside and inside with regard to noise insulation. In the HPG phon-modul® 35 dB / 40 dB, roof window, sub-roof connection, insulation and inner lining, supplemented with special sound insulation measures, merge into one element. All the advantages of the HPG pitched roof elements are retained.

The HPG phon-modul® noise protection roof window element has met with a great response from noise protection experts with the test results available. The legal regulations (noise protection in building construction SIA 181) can thus be implemented in the roof window area with lasting success.
