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.

for more info, my window look like this below .

another way i could think is wall up the window, it is good idea ?

generally casement windows have much better seal compared to what you have now which I believe is louvre window. You need to take care of other gaps in doors, ventilation too.

Seems like the old school windows type from 70" or 80" like that...

You need to change different types...

The full glass type... You go to shop. Ask them. They know the type & gaps everything
