Aluminium Windows | European Quality Window Hong Kong - JS WINDOW

Expert’s Note

“Kerry Emanuel from MIT published his study in 2008 indicating that the intensity of typhoons and hurricanes are only increasing by year due to global warming.


Destructive typhoons are infamously known for bringing down countless windows dating back since decades ago, up to the latest Mangkhut in 2018. I dare say it is absolutely fundamental and necessary for everyone, especially in Hong Kong, to understand the importance of installing a set of quality windows system.


Our duty is to assist the architect and end-user in creating a first layer of protection that will safeguard their cosy home or masterful architecture reliably, and in the long-term. Windows can also become a form of art or a mood setter to imbue your space with the desirable texture and atmosphere.”
