UPDATE

Simonton has proven the windows are performing within specs.

The builder is looking into the installation but since he has never had a problem with other windows he doubts the install is the problem...

Plus the neighbors put plastic on the outside of the windows and the draft was gone. The plastic was just over the window not beyond the window frame...

Just do your research.... mine were 3x's the advertised air infiltration and because the tolerances are so big the infiltration was acceptable.

So another year of 3M plastic kits on the windows.

I have a Yugo for windows I guess my expectations warrant a Lexus perhaps. If that what it takes next time I guess I'm shopping for a Lexus or BMW type windows.

YOU GET WHAT YOU PAY FOR!

Greetings Snolts,

It sounds like it could very well be an installation problem.

The only way I know of to tell would be to remove the window stops on the inside of the house and see if there is any insulation. Also, to see if they are shimmed properly.

The windows, unless defective, should not cause this problem.

Good luck,
Jason

We have air funneling up the channel of the window and the fine dirt the builder spread outside is coming inside. The Siminton rep. said no window is airtight and the air is concentrated to the channels not around the whole window so they are performing properly. He is shipping me foam squares to help with the problem. Humm...
