1. Which is better material for soundproofing: UPVC or Aluminium?
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.
2. Which type of glass is most effective for soundproofing?
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.
3. What is the difference of STC and sound decibel?
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
4. Does thicker glass have better soundproof effect?
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.
5. I have previously installed double glazed windows and there is still sound problem.
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.
