is it FRK? density of 703?

I recently ordered some Fiberglass wool boards from china,it's 48kg/m3 same as 703 with foil.
but im not sure if it's the FRK as you guys mean,so should i still use it in front?
and the density seems abit different with the real 703,because the board is not so hard.maybe the quality isn't as good,but it's cheap.
anyway,i will finish the diy and test the result.

The facing that you have is what is the FRK so you are set.. If you stack pieces together make sure to peal off the foil that would be in the middle.

The inching is from the fiberglass. Make sure when handling it you use face mask, long sleeves, glasses and gloves. The stuff can be NASTY to work with.

Use wide shipping tape, the sticky side...Washing may make it worst, or just let the water run over your arms...

I made some wood frames yesterday and going to buy some fabric to wrap it.
is it any kind of fabric can be protective to block the fibers out of the fiberglass?
