We thank Mr Jolly Wee for his feedback ("Do more to secure windows"; Forum Online, June 17).

The Building and Construction Authority (BCA) recognises that falling windows are a serious issue, and every fallen window incident is one too many.

There are many high-rise buildings in Singapore, and thus, BCA requires all window systems in new developments to be adequately designed and constructed with appropriate materials, components and safety features to meet the current industry standards. Windows following such standards are able to resist imposed loads such as strong winds.

Poor maintenance is one of the key reasons for falling windows.

For most fallen casement windows, aluminium rivets used to secure the friction stays were corroded, and the incidents could have been prevented if the windows were retrofitted with stainless steel rivets and maintained regularly.

Therefore, to ensure window safety, BCA encourages home owners to regularly maintain their windows.

BCA has been actively engaging home owners on the importance of checking and maintaining their windows through the twice-yearly 6/6 and 12/12 (that is, June 6 and Dec 12) Window Safety Campaign and regular roving roadshows at community events.

Everyone has a part to play in maintaining a safe home environment.

Home owners may find window maintenance tips and the list of BCA-approved window contractors at: http://www.bca.gov.sg/window_safety and http://www.hdb.gov.sg/window_safety
