Defect Library · Roseville, MNInsulated Glass Seal Failure in Roseville Homes
Insulated glass units (IGUs) use two panes with an inert-gas-filled space between, sealed at the perimeter. Seal failure lets the gas leak out, creating a permanent foggy or hazy appearance between the panes.
What is Insulated Glass Seal Failure?
Insulated glass units (IGUs) use two panes with an inert-gas-filled space between, sealed at the perimeter. Seal failure lets the gas leak out, creating a permanent foggy or hazy appearance between the panes.
What do we find on Roseville inspections?
We document every failed seal we find with photos in good morning light (failures hide in flat midday sun). 1990s vinyl windows on south exposures are the worst offenders.
What should you do about it?
Replace the IGU (not the whole window) — $200–$400 per sash through a glazing shop. Whole-window replacement only if the frame is damaged.
How this connects to other Roseville defects
Era-defects rarely show up in isolation. A 1965 Roseville rambler that has one of these almost always has two or three more from the same construction window. Our defect library documents the full set we look for, and the inspection report cross-references findings so you can see the pattern.
