I've installed many Integrity jobs and never heard of that issue. Be sure to post back with the findings.

Whats the exterior color of the window and siding?

"Stone White"

Okay.

Just trying to isolate out the temperature noises that we hear on some wood and fiberglass windows.

Have you tried some dry film lubricant between the pieces.

I'll try the dry film lubricant on a few windows. My suspicion is that the interior paint on the sashes had not fully cured before the windows were "closed up" causing a paint blocking(sticking) situation.

Any best practices for contacting Marvin? I submitted an online request for contact 6 months ago and never heard back. Called the 800 number today and left a message with someone named Lauren?

I don't have any best points of contacts but the Marvin folks do peruse the boards.

I am sure Lauren will get back to you as they run a tight ship.

Hi, this is Breanna from Marvin Windows and Doors. We'd love to help you out. Can you send me an email at breannaw@marvin.com so I can get some more detail from you? Thanks!

Update for the thread. Tried a Teflon based dry film lubricant on a few windows. The creaking was diminished for a week or so, but is returning to unacceptable levels.

The responses from Marvin and the local distributor (Moehl Millwork) have been useless. Marvin sent me a flurry of emails, but with no meaningful content or outcome. 10 business days later, the distributor has yet to return my calls to schedule a service visit. I was told after my initial call that service (once scheduled) is 2-3 weeks out. Uffda.

Buyer's remorse here I come.

Whally,

Try a bar of soap and see if that doesn't do it as well.

Hopefully the folks from Marvin will reach out to you again.
