I was requested to make a triangular window for the attic.
A bit odd shape/position for the opening part is due to a support beam of the roof.

I selected a few 2×8 pine boards that had the most straight grain and very little knots (virtually no knots in the result). As I had neved made a window before, then at first I made a smaller version of the window frame to see if the profiles would fit together and how the water would run away. It was rewarding as I saw that the bottom profile needed a bit deeper slope to be more effective.

After making some changes in the design, I cut all the frame profiles on the table saw. Cut them all to length. Connections were made mostly using bridle joints, in a few connections I used butt joints. The opening part was all connected with bridle joints. I used waterproof PU-glue.

Painted the window white using a special window alkyd paint, but that part didn’t turn out well. Each coat of the paint dried ~3 days before it was possible to sand and even after 3 days the paint was still a bit soft and sticky. I will never use that paint again :)

Incredible work, but if you had used aluminum frame at the corners and glass like impact windows instead of the normal glasses then, the life of the window would have increased significantly.

Have your say...
