We finally bought our house and I do finally have a room all to myself for nothing but insulators. This is the west side and it's all shelves floor to window top. The widely spaced shelves I am going to put another shelf between for more shelving and storage. What you see in these photos is only half, at best, of the insulators I have. The small shelves fit perfectly any CD 106,112,113,etc...I can fit about 4,000-5,000 insulators in this room once I finish adding more shelving to the east side wall.
