The customer noticed clouding in between the panes but he thought it was on the surface until i showed him.
It’s not a broken seal, I showed him that it was in between the removable pane that conceals the blinds and the double paned window. We tried to pull the booger apart but the only clip that would release was the one at the top. the bottom clip wouldn’t release so we could access the blinds.
Have you guys come across a newer interior storm window like these that hold the blinds? How do you take them apart?
