A: Protect stained glass with a properly installed exterior protection system that shields against wind, rain, UV, and impact while still allowing ventilation to prevent condensation. Proper installation is essential; without ventilation, moisture can accumulate, leading to mold, lead corrosion, and damage to the artwork. Poor mounting or incompatible framing can also place stress on the glass, resulting in cracks or bowing. If the protection is not installed correctly, it can trap heat and moisture, reduce the window’s lifespan, and even cause structural damage over time. Our studio custom-designs and expertly installs each system to preserve both the beauty and structural integrity of your stained glass for generations.
