DIY Rockwool Adsorbers (Pics)

I recently built some rockwool adsorbers, I am in the process of determining the optimal positioning in the room in PTC Creo however the actual adsorbers are finished. A part of the design intent is to have the panels easily movable and to have near 'infinite adjust-ability' (with relative ease) wherever I want them on the walls.

The 2" thick rockwool panels are 'framed' in drywall edging from Home Depot, this gives the edges structure and should help keep them from crumbling or getting messed up over time. There are two pieces of 1" x 1/2" wide edging per side of the rockwool, taped together. This also made the rockwool much easier to work with.

The PVC tees are arranged every 60 degrees from the center of the panel.


The PVC was hammered down as the glue was setting so it holds in the middle of the thickness of the panel.


Panel with the three wall anchor tees attached: attaching it this way allows me to easily set the distance of the panel from the wall by changing the pvc pieces between the tees; I used three anchor points so that it would always sit 'evenly' (three points define a plane). When determining how they should be placed rotational about the center, I calculated the placement that would maximize (sum of all 3) the distances between the center and the tees. this would imply the 'widest possible stance', it turned out that one PVC tee should have been as close to a corner as possible on the longer side, the benefit was only ~3% further than an evenly spacing though, to keep things simple I chose to make it symmetrical.


The threaded steel rod (3/8") helps to hold the weight of the adsorbers, they are ~10-12 lbs each. There are up to three points where I use 3M command strips to keep the assembly from rotating/falling: the steel rod stand, even being just one foot, makes a HUGE difference in the force the command strips need to apply.


There is a bit of flex in the steel rod, I used nylon string to tension it to help things to stand straighter.


I used electrical tape at the bottom of the rods to keep them from slipping (tape past the end of the rod and then folded over), each pvc tee has 2 washers and 2 nuts holding them in place.


With the 'legs' this tape is capable of holding up the panels, will be switched to command strips when final placement is determined.


I used the 'picture hangers' which velcro together, so I can remove/clean behind the adsorbers easily.
