Doors and Windows - Framing Your Own Window

Has anyone ever framed their own windows? I have a log house that has large special sized windows so buying vinyl would be extremely expensive. For the larger windows I thought I would buy 1/2" glass and frame it in. Of course I would seal and caulk it. Has anyone ever done this? If so how did you do it?

In the log homes I have had experience with, the windows are installed as the logs are placed with splines holding the window in a groove in the log end to allow for settling of the logs without adversely affecting the window framing. How old is the log home? The window sashes themselves can be removed and replacement windows installed in the openings, but you can't change the 3" header space provided for settlement. So, by leaving the frame in place, you can install your glass as planned, but I would use insulated glazing units rather than the 1/2" glass as you stated. The single pane glass won't give much insulation value. If the windows are less than 18" (different localities have different measurements) from the floor they will have to be tempered.

How old is the log home?

Thanks for the reply. The house is actually an unfinished 20 year old home. So I would think most settling has already occurred. I figured that most windows would need to be tempered. There are just square holes in the logs, meant for the windows.

To add to chandlers reply....windows or insulated glass units (igu) over a certain square footage will also need to be tempered. Its an automatic thing, any glass shop that sells IGU's would be able to tell you the requirement.

I know I could probably ask locally, but what thickness? 1/2"?

Well, IGU's are basically made by the spacing between the glass. 1/2-5/8 is a common spacing for low end windows...3/4-7/8 will give slightly better performance. Whatever you decide..you want a LoE coating.

If you mean actual thickness of the glass...1/2 would be very expensive. I think 5/32" is common for window glass.

In the last 20 years egress (escape) in bedrooms has changed. Also maybe light and ventillation requirements for certain rooms. The existing cutouts maybe too small.
