Every double pane window eventually fails. There is no such thing as a fail-proof thermal pane window. Wood framed windows tend to last 18 to 20 years (if well maintained). Newer, high-end wood/aluminum clad windows last about this long too. Traditional aluminum frame windows typically last 12 to 15 years. Vinyl framed windows may make it 10 years if they have standard box spacers. However most newer vinyl framed windows have a low-quality Intercept Spacer and these windows begin failing in 5 to 8 years.

Sun is the biggest cause of window failure, which is why your south and west facing windows usually fail first. Sunshine causes both a process known as “solar pumping” and the hardening of the sealant that forms the seals of the window.

When sunshine hits a double pane window the air inside heats up significantly, (think of a car on a hot day!) causing the sealed window unit to expand and pushing air out through the semi-permeable seals. In the evening, the window cools and contracts, drawing air—and humidity—with it. Day after day, year after year, this cyclical expansion and contraction occurs, stressing the window seals and filling the air space with moisture.
