The name sounds familiar, but I don't remember that company name (Its been so long, now I dodn't remember what I did yesterday :laughing.Greg, do you remember Trilco? Big Andersen, Wenco, and Atrium patio door supplier in the '70's and '80's. They had a place around Toms River and also one in Pemberton.
They were the ones who pushed out a lot of those Blefa skylights.
What a good company that was, one stop and you got your lumber, stairs, windows, kitchen,millwork, etc.I remember when BlackStone was around.:thumbsup:
Maybe it was what the suppliers here sold, but I only remember the operable Roto's as having the linkage that lifted them, not the struts.I'm going guess "Roto" brand. Roto looks just like Andersen, because they are. Or were. I never put in a unit that would open, so I can't say for sure. About 20 years ago, Roto was bought out by Andersen. That is why they look so similar. Andersen didn't change the design, just the name on them.
One thing about Roto is they don't have their name on them. Anywhere that I could find.
I thought about the glass after I left the place. It's also possible there is an ID in the insulation spacer in the glass.Maybe it was what the suppliers here sold, but I only remember the operable Roto's as having the linkage that lifted them, not the struts.
OP, if they are Andersen I would think they would have the logo etched in the glass?
