Three Indicators of Failed Window Seals

Modern windows are designed to provide thermal insulation and prevent air leakage, but over time, their seals can fail. Champion Restoration and Construction in Chantilly, VA, highlights the key signs of failed window seals and what to do if you notice them.

1. Condensation Between Glass Panes

What to Look For

  • Water, Fog, or Frost: Moisture visible between the glass panes is a clear indicator of a broken seal.
  • Humidity Fluctuations: Increased humidity changes within the panes cause condensation.

Why It Happens

  • Thermal Barrier Failure: The rubbery sealant acts as a thermal barrier, and its failure allows moisture to enter the space between the panes.

2. Distortion of the Glass

What to Look For

  • Visual Distortion: Glass panes appear distorted or warped even without condensation.
  • Gas Equilibrium Disruption: The inert gas between the panes is at equilibrium, and a broken seal disrupts this, affecting the structural integrity.

Why It Happens

  • Seal Breakage: When the seal breaks, it affects the balance of the gas, leading to distortion.

3. Dirty Windows from the Inside

What to Look For

  • Persistent Dirt: Dirt, bugs, or dust trapped between the panes despite cleaning the windows.
  • Impossibility to Clean: The dirt inside the panes is not removable through normal cleaning.

Why It Happens

  • Barrier Failure: The seal acts as a barrier to keep out contaminants. A broken seal allows dirt and bugs to enter between the panes.

Causes of Seal Failure

  • Defective Manufacturing: Poorly manufactured windows can have inherent seal issues.
  • Poor Installation: Incorrect installation can lead to early seal failure.
  • Extreme Weather Conditions: Severe weather can damage seals over time.
  • Aging Windows: Over time, seals naturally degrade and fail.

What to Do Next
