This is how I went about to build our attic windows.
The windows had in fact four layers:
- 2 layers for the frame: the layer that would fit into the window opening, and the layer that would be fixed to the inside wall of the attic
- and 2 layers for the window : the layer that would fit into the frame, and the layer covering the frame.
To make it easy for myself to keep all the pieces sorted, I named the four layers L-E-O-N . Yes, Leon was born a few weeks earlier.
Each of the parts in a given layer was glued to two other parts in the second layer. In that way, I ensured strength for the whole piece.
I used a jig with the exact dimensions of the window openings, both for gluing the parts, and for routing the inside and outside of the pieces.
And the end result : look Here
