I'm getting ready to build a closet around the cyclone to try to quiet things down some. I guess that a prehung steel exterior door with weather stripping would be the best choice, but that gets a bit expensive. On the other end of the scale, a cheap interior hollow core interior door - would this do enough to be worthwhile? Or would just hanging a blanket over the hole be better?
What have you guys that have built cyclone closets used?
