[Greenbuilding] salvaging insualted glass units

[Ken Beiser]

I have a few insulated glass units that have failed edge seals.  They are like the old Hurd Superglass (triple glazing) which claimed R-6 center of glass.  Mine was made by Wilmar in Canada.

I was hoping to salvage one by removing the edge seals and ending up with two sheets to use in a single glazed low mass sunspace.  If the Superglass is Low E, which I do not know, am I using the wrong kind of glass for the sunspace?  Is it a Low E coating and is it "removable"?  Would it be on both sheets or is the Superglass single Low E coating?  If only one Low E sheet, which sheet. inside or outside will be Low E?

Thanks for all your help!
