So pleased with m lattice ceiling tiles. They are absolutely beautiful. They are made out of pvc/plastic, so they are very light weight, which should make installation a breeze. They are 2’ x 2’ and can either be hung as a suspended ceiling or glued straight onto the ceiling, since they are so light weight! One box should be enough to do my hallway and I haven't gotten them up yet, but I can't wait until I do! They will bring a whole new look to an area of the house that is often overlooked!
