Windows with increased noise insulationThe requirements for a building's protection against noise are laid out in the Regulation STR2.01.07.2003. It sets forth the standards for acoustic indicators for buildings and the noise levels for their parts (windows and doors), exceeding of which may pose risks for human health.According to the sound insulation characteristics, all windows and doors are divided into the following classes: E, D, C, B, A - being the highest class. The indicators for sound insulation are measured in laboratories and has to reach 43dB in the A class windows. We offer you wooden windows, outside of which is binded with Gutmann aluminum panel, glazed with a sound insulating glass packet and additional acoustic seals fitted in a frame. Acoustic characteristics of our windows have been tested by the laboratory at the Institute of Architecture and Construction where it was determined that sound insulation indicator of the windows is Rw = 45dB (A class). |
