Hello Christine. Thanks for asking about the floor. It is a concrete "overlay" or "finish layer" with a black/brown acid stain - then a sealant coat.

She said door, not floor. Could you tell us what kid of door it is?

My apologies. It's a Simpson door, French #7001 with insulated glass.

I would like to purchase 11 - Simpson French Doors #7001. Do you have a source to recommend?

Dick, we have purchased these through McCoys, or BMC. good luck - they are fantastic doors.
