We finished the sunroom earlier this year with ceiling tiles from Ceilume. These are semi-rigid plastic tiles that attach to the ceiling w/staples and/or glue. We spray painted the tiles before installation then added the decorative strips between the tiles to cover the staples.
This sunroom was added to the back of the house, behind the kitchen. We had a tin ceiling in the kitchen so the Ceilume ceiling really fits in with the rest of our 1850's Italianate.
2015 has certainly kicked off with a bang! It has been a busy, busy few weeks. I am momentarily jetting off to warmer temps to the always exciting Las Vega...
