DensShield Tile Backer 4-ft x 8-ft x 1/2-in Waterproof Gypsum Backer Board Sheets

Charlotte Wood Middle School, Danville, California

It was 1991, and our company was framing the entire middle school. The Charlotte Wood Middle School was built out of Douglas Fir Lumber, Pressure Treated Plates, and different kinds of Plywood. I negotiated a contract with a lumber mill in Oregon to provide all the dimensional lumber for the project. I had lumber being delivered from their mill for months. GREAT PROJECT!
