I was one of the original posters to this thread, owning Semco windows that were less than 5 years old and having serious problems that Semco wouldn't acknowledge.
I thought everyone would like to know that a few years ago we replaced the Semco windows windows in our home--quite expensive given the number of windows.
As the Semco windows were being replaced, I took the opportunity to disassemble the sash on a few of the windows to see why there was water coming into our home.
Recall, we have casement windows, so the sash, the movable portion of the window, is easily removed. Each sash consists of the double pane glass unit surrounded by a wood frame. On our casement windows, the crank opens and closes the sash and there were two levers to secure and lock the sash closed.
I took the sash and using a wood saw carefully made a perpendicular cut through the horizontal members of the wood frame at the top and the bottom, allowing me to separate the wood frame from the glass.
Examining the saw cuts, the wood at the top of the window looked like new pine.
In contrast, the wood exposed by the cross cut of the bottom frame member was gray stained through and through and rotting indicating water exposure. The contrast between the top member and bottom member was striking, new wood vs. gray. It appeared that water was running down the glass on the outside of the window and getting between the glass pane and the wood frame, soaking the wood through. This pattern repeated on all the windows I checked.
As I suspected, it appears the water pouring through our Semco windows during heavy rain was entering through the sash, not around the sash, and not around the complete window assembly.
Based on my experience, I would not recommend Semco windows. Not just because our Semco windows leaked, but more importantly because of their denial of any problem and poor customer support.
