I am looking for special type of 'soundproof' curtains which can more effectively block sound, as there is lot of traffic noise coming to my condo.

The adage I read is that the thicker and heavier and more pleated the curtain, the better sound absorption = which means more material and $$

I have checked with one curtain company which has a type of soundproof curtain used for AV rooms. I notice the material is 75% polyester and 25% rayon. Most other velvet curtains i notice are full polyester, so i wonder is it the rayon that make a bit of difference there. It is not really a blackout curtain but i suppose it will cover most light as well.. I think it is quite pricey at RM120 per meter (currently offering discount of 30%), and was also saying something that the fabric roll is smaller and potentially more expensive to cover a large area.

Has anyone got experience buying these type of curtains before and have recommendations?

yeah i know..just looking to at least reduce sound not completely block. Changing window is a bit impractical and may be too costly..as my unit has full glass from floor to ceiling

so can you still open the window with this plastic glass there? mind to show picture?
