Ping Jon Risch (again)

Hi Jon-

Well, here in New Zealand they do things a bit 'different' than back in the States, apparently.

I noted in your response to my recent 'Ping' that in reference to the corner bass trap SQ&E approach I'd like to use in my new Music Room, you made mention of lower R-value insulation having more 'paper backing' per roll and thereby being better at absorbing deep bass (which makes great sense), so I went to the local Bunnings and Mega Mitre 10 (NZ's versions of Home Depot/Lowe's) and discovered the bad news about fiberglass insulation rolls (or batts) here in NZ.

Apparently, the retailers here only carry fiberglass insulation that has NO paper or foil backing whatsoever. The plastic bags (or rolls) of insulation you can purchase here are simply stuffed very tightly with plain fiberglass in varying sizes, shapes and densities, but just fiberglass on the inside (and again, with a thin plastic bag cover that is VERY tightly fitting on the outside, BTW.) The bags are roughly 4' tall and between 15" to 18" in diameter, and feel very dense and heavy. (FYI-the bags are not exactly round cylinders, but more like a rounded rectangle shape, again about 18" x 15".) Can these be employed successfully as SQ&E corner bass traps? Any drawbacks?

The only insulation widely sold here in NZ that has any kind of paper backing is a type of 'wrap' that is employed for water heaters, but it is polyester batting that is glued to a somewhat stiff thin brown paper with foil on the exterior. I don't know if that will possibly work as an SQ&E corner trap, being polyester on paper/foil, and the diameter of the bags they come in are only 10"-12" (but four feet long, thankfully!) Also, the plastic bags they are packaged in are not really super-tight (like the VERY tightly shrink-wrapped fiberglass rolls described above), but only semi-tight (not loose, though), and have an open top that is gently twisted shut and only sealed with a zip-tie (although I could twist the top really tight to get a decent seal, then clamp it shut.) Also, the plastic bag cover for the polyester/paper wrap insulation is just a little thicker than the very thin plastic used on the fiberglass rolls.

I was hoping if the fiberglass insulation rolls described at the outset were not useable as SQ&E corner traps, that maybe the paper/foil-backed polyester rolls might be.

Of the two rolls, which would you suggest, if either actually will work?

Sorry to pester you, but I was pretty surprised that paper-backed fiberglass insulation rolls are simply not stocked here in NZ by any retailers.

Again, things are done a little 'different' in the land down under. :-)

Many thanks for your help and guidance. Really appreciated.

Cheers,

WS
