Insulated door curtain that opens down the middle & closes with heavy duty magnets in the fabric. Measures 90”X 206”. Used it last winter- in great condition. Kept out the drafts in my sunroom. Great for keeping warm air out in the summer as well. Did not use the included Velcro or tacks b/c it was not wide enough. Make sure to measure from middle of trim not the inside of the door frame.
