Common problems in Beauharnois

Understanding the three types of fog in a sealed unit

Not all fog is identical, and the type of fog determines whether defogging is the appropriate solution. Dry fog (or halo) appears as a permanent whitish haze between the panes, often more visible around the edges. It is caused by mineral deposits left by repeated evaporation of moisture that has infiltrated and dried out over time. This type of fog is the most common and generally responds well to defogging.

Wet fog appears as visible droplets or condensation between the two glass panels. It indicates active moisture infiltration through the broken sealant. If the wet fog is recent and the sealant is not too deteriorated, defogging can be effective. In cases where the infiltration is severe and long-standing, sealed unit replacement is often preferable.

Misty fog presents as a diffuse, uniform haze between the panes. It often results from a combination of mineral deposits and residual moisture. This type of fog can be more difficult to treat by defogging, and our technician will honestly assess the chances of success before proceeding.
