Why Sealed Units Fail

Sealed units are engineered to keep 2 or more panes of glass separated by a spacer that is filled with an inert gas (generally argon or krypton) and sealed with a durable sealant. In time, numerous aspects can jeopardize that seal:

Common Causes of Seal Failure

How It Affects Performance

Age of the unit (usually 15‑25 years)

The sealant breaks down, enabling moisture to penetrate.

Thermal tension (extreme temperature level swings)

The spacer expands and contracts, creating micro‑cracks.

Poor setup (inadequate spacing or pressure)

The unit might be mis‑aligned, stressing the seal.

Mechanical damage (impact, vibration)

Small fractures can broaden, breaking the hermetic barrier.

Chemical exposure (cleaners, solvents)

Harsh chemicals can deteriorate the sealant over time.

Understanding these source helps house owners prepare for when a replacement may be essential and plan accordingly.

• Drafts near windows or doors, specifically during colder months.
• Rising heating or cooling costs without a corresponding change in thermostat settings.
• Mold or mildew building up on the interior frame due to excess wetness.

If any of these symptoms appear, it's time to search for “sealed system replacement near me” and set up an assessment.
