Although premium double-glazed windows can withstand strong winds, they may not be able to withstand the strong impact of hard objects under strong winds during typhoon season in Hong Kong. The size of regular wind-proof rolling shutters on the market is much smaller and takes up less space than the old-style wind-proof rolling shutters. Therefore, many people living in Hong Kong gravitate towards installing wind-proof rolling shutters and gates on their front doors and windows to provide a reinforced protective layer for their glass windows and doors. In addition to being wind-proof and anti-impact, wind-proof rolling shutters are extremely difficult to forcibly open, providing an additional layer of security and lead time to contact emergency services. Moreover, the wind-proof rolling shutters made from aluminium alloy have the advantage of reflecting sunlight. When the rolling shutters are completely closed, an insulating air cushion can be formed, effectively providing noise and temperature insulation properties.
