That being said, if the meeting rails are not snug and the locks tight, they can leak on that seam.

Alside also has released what they call "Energy Tabs" which go on the edges of the sashes at the meeting rail that cut down significantly on air leakage at the corners. Call your installer about those first and see if that solves the problem.

Vinly replacement windows work best when they are locked. Some locks actually push the top sash up and the bottom one down to tighten them into the frame. Sometimes when locked, you are able to move both sashes up and down in the frame usually indicating that one of the sashes was made too short. When properly locked, the sashes shouldn't move up and down at all.
Additionally, you can check the bottom and top sash daylight opening by just opening the sash a little bit to see the light line/space. Is it level?

If the installed jamb is not plumb and level, your lines as described above will not be even all the way across. Thats a poor installation.

Things happen when windows are made and again when they are installed.

Check these little things before you pay your balance.

Hopefully they wil be able to get your window install straightened out. It's possible that the original installer over tightened the stiles and bowed the frame of the window. Do the windows seem to operate smoothly when you raise and lower them? Another reason to avaiod the Sheffield is it uses a "snap-in" type sill. This is an undesirable design because it relies on the internal part of the window as the major path to drain water away from the window. If water can drain through a window then air can seep in through the same path and it usually does to some degree.

A big +1 to mmarse's product recommendations. :)

This rumor is complete BS.

Alside deals with each Window World vendor on a 1:1 basis. I am sure there are a few vendors that are late on stuff but nothing on a national scale that would cause and issue on their balance sheet.

They are doing just fine, if not better than about 95%, from a company health standpoint.

Wayne Gorell was saying everything was wonderful and great just a few months before he filed for bankruptcy.

Btw, windowsonwashington, do you honestly believe each local Window World buys direct from AMI? C'mon, you are smarter than that.

My relationship with the National sales manager extends beyond that of the relationship that reporters and other industry folks had with Wayne Gorell when quizzing him about the health of his company. Wayne Gorell was also reporting this to outside sources that would print this material in addition to the fact that there were multiple indications of poor company health (renegotiation on labor agreements, rumblings of chapter 11, slashed hours at the factory, etc, etc)

ohiowindoze,

I am not sure you understand how the Window World/AMI relationship works. Window World dealers order their product direct from AMI/Alside via direct order forms and the product comes direct on Alside trucks.

The way that Window World makes its money from the dealers (via product) is by Alside issuing Window World a commission of sorts on every window that is ordered.

Pricing levels are based off of set volume marks, but Window World is getting their money from AMI.

I have ordered windows for Window World and this is how it was done in my presence.

Window World provides a good chunk of Alside's business but the fact that they are opening additional branches and the branches near me are always packed is not indicative of a company on the verge.

Like HomeSealed said, in the absence of any real facts, the information that I have been provided is more valuable and vetted than anything in this thread saying otherwise.
