The Problem
Many of today's energy efficient windows offer glass packages with a full metal spacer. The problem is that this highly conductive metal-based insulating glass spacers cause problems.
The edge of the insulating glass is the most vulnerable to heating and cooling loss. This usually leads to condensation. It's a problem that looks unsightly, and over time, it will stain wood, peel paint and rot frames.
Not only that, but window condensation (top picture) causes and contributes to mold growth (lower picture), a sinister presence hidden from sight deep inside window and wall openings.
In fact, poorly built or installed windows are a prime indoor mold source whose occurrence is more and more being linked to child asthma plus increases in general respiratory illness, allergies and outbreaks of fungal diseases. |
