Re: deck door dual pane glass replacement?
yeah, I'll go to Home Depot to price out glass vs new door!
Aha! Finally something I can chime in on. In MN, I would get this piece of Clear Tempered Insulated Glass (or a patio glass IG Unit) at cost for about $100. That was going directly to the manufacturer in town to pick it up and install it myself but you would need to provide your own measurements.
Remember it's W X H X O.A. (or overall glass thickness, you will need a micrometer to mesasure this, or some creativity by removing the glazing beeds that hold the glass in and then using a piece of marked carboard to obtain glass thickness).
It's most-likely 7/8" or 1" O.A. Measurement. Look for Glass Manufacturers near you, and the biggest one isn't going to be the cheapest.
EDIT, that piece of glass should actually be cheaper because its not as large as a full width SLIDING patio glass piece. They usually price the glass by United Inch.
