Warped channel for snap in glazing

A home owner from Cincinnati says:

Hi,

Just moved into a house with a lot of Andersen Windows. There are a few on the east side of the house (lots of sun?)whose bottom snap in vinyl glazing has popped out. It "seems" as if the channel that the glazing snaps into is warped to the point that the glazing will not "snap in" anymore. I "guess" 40 years of sun has warped them?

In any event, is there a way for me to flatten or straighten the channel to snap the glazing back in? Would a heat gun soften things up enough to re shape or would that make an even bigger problem?

Thanks for any thoughts,

Jeff

You need to replace your vinyl glazing. Andersen used two different insulated kinds of glass 40 years ago, each with a different thickness. Look at the back of the vinyl glazing to see if it has a number. If not, remove a sample of the glazing and send us a photo of the cross section.

Hi Paul'

Thanks for the quick reply.

I took a look and see a # 38 on the back side of the glazing. (Terratone color)

The center of the channel that the glazing should snap into is quite a bit wider than the corners.

Is that a problem or is that the way it was manufactured?

Again ...Thanks for your help
