Hello everyone.

http://www.storesonline.com/site/490194/product/FPC-RS-448-ROLL

that link is for a polyester batting that i'm going to use for the front of my mid/high absorbers... just wondering if anybody knows, it says it has a light resin coating over it, but i'm guessing that all polyester batting has this...
Anyone know about polyester batting, if it reflects rather than absorb highs?,

Also over the polyester batting i'll be using burlap fabric... just wondering, it seems pretty thick, the thread they use to make burlap, I guess it's weaved pretty loosely.

I'm using the polyester batting/burlap to stop the escaping fibres....

Thanks for your time and help.

Jason.
