I purchased a mobile home that has had its windows redone since DOM. I would like to have additional windows put in, and would prefer them to match existing. Only problem, I can't find any identifying numbers, letters or anything on the windows except an outline of PG is engraved on the metal bracket/rise of the lock (pic attached). I've googled endlessly and can not figure out who manufactures these windows?

They are double-glazed, double-hung casements, non-tilt, 44.5"x51" @ 4 "panels" across (panels created by vinyl dividers between panes).

Thanks in advance!

    Unfortunately, there's no guarantee the maker of the lock hardware is the maker of the windows. – Ecnerwal Jan 8 '16 at 12:29
  • Look for a faint etched stamp at one corner of the glass. – isherwood Apr 8 '16 at 13:26

That logo looks like Portland Glass, located in lovely Portland Maine.

What is your location? There are literally hundreds (maybe thousands?) of aluminum window manufacturers. The one that is most likely is PG Aluminum; a South African manufacturer.

  • haha, wow! I'm in Maine, on the coast. Probably NOT the SA mfg. but i will check into it anyway! thank you! – tBa Jan 8 '16 at 15:12
  • Yeah, probably not African. Maybe the wonders of technology would allow you to search with that picture of the maker's mark, to find similar images? – Jimmy Fix-it Jan 8 '16 at 18:17
