Doors and Windows - Wood exterior door--new glass

I purchased an old wood entry door from a salvage yard and had it refinished. I'm preparing to replace the glass. The original glass was 1/8 inch standard glass--nothing special about it. I plan for the replacement to be double-pane low-e tempered glass. It'll finish out at about 1/2 inch thick--I've already checked the door and it'll accomodate the extra thickness.

Before I order the glass, is there anything special I should know--a particular way to install that'll affect the overall size for example? Should there be any type of 'padding' where the glass meets the wood--foam or caulking or something?

I look forward to your responses. Thanks,

Brian

The glass size should be at least 1/8" less then the opening. The bottom of the glass should sit on 1/16" rubber blocks. The glass should be set against a bead of silicone. Keep in mind the double pane glass will have a minimum of 3/8" of spacer that may be visible if the moldings are not at least 1/2" thick.

That's exactly the feedback I was looking for.

The 1/16 rubber blocks--are these something special that I need to purchase, or can I make them myself?

Thank you!

Brian

You should be able to get them where you purchase the glass if not you can make them.
