## Questions & Answers

**Q: What size are these panels? In the description it shows: 0 x 0 x 0. Not willing to pay for nothing.**
A: I apologize for the oversight and appreciate the heads up on the missing info on the listing.  The Owens Corning 703 1" dimensions are 24"x48"x1".

**Q: Can it be used in an exterior application?**
A: Yes

**Q: This say semi-rigid. is it flexible enough to wrap our pvc waste water pipes to block the noise of flowing water?**
A: probably not, it's actually pretty rigid and holds shape well. so if you tried to bend it around pipes it would probably tear.

**Q: Does this really weigh 48 lb? That would mean each panel is 4lb**
A: Each sheet of Owens Corning 703 1" Fiberglass weighs approximately 3lbs each.

### ⭐⭐⭐⭐⭐ Great Product!
*by M***B on July 23, 2026*

Great product & fast shipping!

### ⭐⭐⭐⭐ One part of multi-pronged acoustic management strategy
*by V***N on May 30, 2025*

used on exterior on top of 1.5 inch rigid styrofoam panels then R-Panel in top of this. Wall facing the railroad about 100ft distance. After installation, the agonizing train horn is now bearable and doesn’t cause pain. So it does help noticeably. Nothing will be perfect in sound control but rather coordination of multiple strategies to get all frequencies to acceptable living levels. this is one of those strategies.
