Common Causes of Seal Failure

How It Affects Performance

Age of the unit (generally 15‑25 years)

The sealant breaks down, permitting wetness to infiltrate.

Thermal stress (severe temperature swings)

The spacer broadens and contracts, producing micro‑cracks.

Poor setup (insufficient spacing or pressure)

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

Mechanical damage (effect, vibration)

Small cracks can expand, breaking the hermetic barrier.

Chemical exposure (cleaners, solvents)

Harsh chemicals can wear down the sealant over time.

Comprehending these source helps property owners anticipate when a replacement may be essential and plan accordingly.
