Partition Wall
Found this excellent blog that talks about properties in Malaysia. In one entry, they wrote about the different type of bricks used to construct our homes: "Ever wonder why in your apartment you can hear your neighbour’s TV and hi-fi through the walls? Or at night, you can clearly hear them talking loudly or carrying redecoration (like hammering nails) even though your balcony sliding door is closed? And ever wonder why this never happens in other people’s houses or apartment, just yours?"
