Our glass cellar doors are well-insulated at 3/4" thick. Frameless glass doors always look elegant and modern at the same time, perfect for this chic, plush Florida home. On the top of the photo, you'll see the grilles that cover our wine cellar cooling unit, making way for a very clean wine cellar ceiling look.
