recently there are few neighbor who will cook in the night hour , sometime even at 3am , the smell include petai, frying chicken, plastic smell and so on. The earliest they cook is around 11pm - 1am

i need window that can block at least 99% of the smell coming into my room , this also affected my father as well.

any recommend please inform me.
