A normal aluminum window is able to withstand a reasonable infiltration of wind, rain heat and sound.

UPVC Soundproof Window performs even better by having a thicker frame, precision locking mechanism, durable accessories and most importantly improvised medium (i.e multiple layer of premium glasses.)
There have been several ways that noise can affect human health, comfort and efficiency.
For mild cases, it strain one's sense as a results of slow but persistent noise i.e. moving traffic, animals, neighbour noise; this causes frustration, difficulty in sleeping or concentration thus affecting work performance the next day.
i.e slamming of door, honk, shouts; which can be more harmful than a continuous noise.
Such as chronic headache, hypertension, undesirable change in gastro intestinal activities behaviour and emotional stress.
Answer: uPVC (Unplasticized PolyVinyl Chloride) has numerous benefits over Aluminium. uPVC is more rigid, durable, and its unique structure within its frame makes it tough for sound and heat to penetrate your windows.
Answer: Laminated Glass would be your best bet. It is very similar to a hamburger. Basically it has multiple layers of glass that has a layer of PVB (Polyvinyl butyral) in-between that helps to trap sound wave.
Answer: Sound Decibel is the unit measurement of sound (Lower the better). While STC means Sound Transmission Class, refers to an integer rating of how well a building partition attenuates airborne sound
Answer: This is common misconception as it makes logical sense that thicker glass is stronger. However, the key to insulate sound is the quantity and quality of the barriers in the window. Both PVB and Vacuum Air space between the layers of glasses are additional superior barrier to block off sound and heat.
Answer: Here are some checklists to check if you have purchased a legit soundproof window:
– The window frame should have at least 5 small chambers within its structure
– The window frame width and thickness should exceed your existing old window frame quality
– The window handle must be able to have a full lockdown and fill the empty space when fully shut and closed.
– The joinery (corner L shape) of the window frame should not have a visible joint.
