Why are my Willmar Windows (Jeld-Wen) sealed glass units repeatedly failing?
Subject: Willmar Windows Jeld-Wen Ontario Canada
In 1997 we purchased 78 top of the line windows and doors from Willmar Windows, a division of Jeld-Wen. These were “R+10 with Heat Mirror, Metal Clad Wood” windows and doors.
Since the first year there has been a steady rate of seal failures. In 2004 Willmar decided to replace all of the glass units. In 2007 Willmar finally accomplished this.
They were replaced with glass units called Tripane T2SA with “Triple Solar Shield, 2x Low E and Argon”. Since 2007 we have had 12 seal failures in these units.
We are about to contact the company about these seal failures. In 2007 Willmar gave us a 5 year limited warranty on the Tripane T2SA glass. At the time, this glass was being manufactured with a twenty year warranty.
The framed windows are 3’x5′, 3’x3,’ 3’x3.5′, and the doors are 3’x8′, 3’x 6’8″.
All exposures are effected with the southern exposure having the highest
failure rate. The windows are awning style, with opening and fixed both failing. We have no curtains, no stained glass, no baseballs, no ice forming under the glass units, and no reason we can think of for what is causing this failure rate.
Since your magazine has a wealth of knowledge, I thought I would do some independent research and I am asking for your thoughts. Is there a known cause and remedy for this sad and foggy situation?
Thank you for your help,
