Insulated Fiberglass Energy Star Door, Fiberglass Door Frame. 36" x 80" x 4" door opening. Door has 1/2 lite beveled mosaic glass with zinc caming. This door has never been installed! Ordered from Lowe's for our home remodel, we were asked if our house had 2x4 construction. It does, we had it foamed from the outside and saw the 2x4's. BUT, the walls are 7" thick, because they are double walled, we weren't asked that. The door has been primed and is painted antique white- this was done before we found the door thickness issue, and Lowe's won't take back painted doors. Our loss is your gain- this is a $2,100 door, we got $200 off for getting a Lowe's card... so we have $1900 invested- make us an offer we can't refuse.
