Doors and Windows - Window replacement from original manufacturer?

We need to replace several windows that lost their seal and show condensation between the two layers of glass. To buy time, we removed the windows (crank out style) and sanded and repainted the interior wood of each window and the crank hardware. My husband believes we have to order windows from the original mfg. I don't really see anything special about these windows and we cannot find a manufacturer's name anywhere on them. The hardware is stamped "Truth". These windows are approximately 18 years old and were installed by the previous owner. I don't think repair is the way to go as the wood on some of the windows is blackened by repeated moisture absorption, but may respond to bleaching. The original factory finish was probably not great and I'm thinking the windows weren't properly painted (varnished) after installation. Any help with this would be greatly appreciated. Sue

Any glass shop can replace the dual pane glass but if you need the entire sash then it must be from the same manufacturer. Truth is the manufacturer of the hardware.

Did you happen to notice if the sashes had a phillips screw on the interior face of each corner (where the rail and stile overlap)? Or if there is a marine glazing bead around the glass? (it's like a hard rubber strip next to the glass... about 3/8" wide, and goes around the perimeter of the glass on both sides.)

I'm not familiar with every type of window, but if it's the type described above, the glass is very easy to remove and replace, and yes, that would be the best way to go.

I didn't find any screws on the interior of the sashes/stiles and no glazing bead next to the glass, althought I'm sure there must be one. Between the glass panes, around the perimeter of the window, it looks like an aluminum strip the thickness of the space between the panes. I thought it was probably something to with the Argon seal or whatever is used in windows nowadays. When I varnished I extended he paint onto the glass, but it's clear and doesn't seem to be hiding anything like you described. So, it looks like I'll have to find the mfg. We examined the windows carefully and didn't find any identification on them. The outsides are vinyl clad and no ID there either.
Thanks for your input, though. My husband wins this one!

The aluminum that you see is the spacer for the 2 glasses. Look at the spacer again for any imprint of letters, sometimes it indicates the manufacturer but most times it's the manufacturer of the glass unit. Did you look in the corners of the glass for any logo or name that might be etched in the glass? If you can post some pictures, someone might be able to identify the window.

Hi Johnam,
I think my husband did check the aluminum - I know he checked the glass and there was nothing. We'll check the aluminium spacer again, though. And, I'll do as you suggest - post a picture and see if it rings a bell with anyone. Since it's starting to get cooler, we'll probably wait till next summer. They're painted and for now that's good enough to get us through winter. The moisture between the panes is what really bugs me.
Thanks for your help!

If you do manage to take some digital pictures, crank the window open and take a closeup picture of where the glass meets the frame on both the inside and outside of the window sash. Such a picture might show whether the glass can be removed without taking the sash apart. Your windows may have a removable glazing strip on the exterior, or a removable interior stop in the inside.
