why acrylic and not polycarbonate or Lexan?
« on: August 08, 2008, 02:06:03 AM »

Hi all,

I like the idea of magnetseal windows, so I have been reading this :
http://www.soundproofing.org/sales/magnetseal_windows.htm
But what I dont undestand there is that it was written "Do not use polycarbonate or Lexan",
In all my researches I have found that polycarbonate is far more better than acrylic in many ways, specifically in "Durability" and "high Impact Resistance" properties of polycarbonate.
Acrylic is cheaper but I am not sure is better for soundproofing.
So please can someone explain to me this.

Thanks

Randy S

Polycarbonate is a harder material and helps transmit sound like wood or metal, while acrylic is a softer material that will help absorb vibration and flex with the sound wave....
