There are no plans to retrofit Housing and Development Board (HDB) flats with double-glazed windows as the current single-glazed windows are sufficient for noise reduction, Senior Minister of State for National Development Lee Yi Shyan said in Parliament on Tuesday (Aug 18).
“When planning HDB towns or estates, HDB will conduct noise modelling, with a view to locate and orientate the buildings in such a way as to help minimise noise to dwelling units,” Mr Lee said in response to a question filed by MP Arthur Fong.
For example, multi-storey car parks are located between blocks and MRT lines or expressways to act as a noise buffer, Mr Lee said.
“HDB flats are designed to allow for natural ventilation through open windows. HDB’s single-glazed windows reduce noise, when the windows are closed, although this reduces natural ventilation as well,” he said.
Residents who wish to install double-glazed windows as an added measure can apply to HDB and the Building and Construction Authority for evaluation, he added.
