Will tin ceiling tiles cause problems with condensation?
No worries. A tin ceiling won’t rain on your new kitchen parade. You won’t have any condensation problems as long as you add a vapour barrier and insulation before installing it, as you would with any ceiling construction.
For spaces not heated in winter, use tiles coated on both sides so they won’t rust. You can buy tiles unfinished and finish them yourself by painting or clear-coating them with polyurethane, varnish, or clear lacquer. Or spend a bit more for pre-finished tiles. Install them directly onto drywall, using any glue that adheres to tin (but avoid contact cement, as it’s tough to reposition a tile once it’s been laid), or onto sheets of 1⁄4″ plywood, using either nails or staples.
