Hello:
Moving into a house with a glass sliding door leading to a deck.
This is the typical type of sliding glass door I guess; one large single sheet of glass in an Aluminum frame with a handle and simple lock on it.
a. is there any simple way to tell if the glass is thermo-pane, or some other (good) insulated type of construction ?
b. the door track (on the floor) is pretty bunged up. Do they sell replacement tracks of a generic type, as I have no idea what the brand is. The door's probably about 25 yrs of age.
Thanks, Bob
