We noticed this one yesterday on the window above our bed in the bedroom. To be honest, we're stumped on it. It's the inside pane of a double pane window, and as can be seen it has spidered and broken out pretty well. The crack has grown since I took the photo(I have since shrink wrapped it to hopefully at least contain any glass shards should it fail completely).
We're certain neither of us hit it, as number one neither of us remember having done that, and number two you would think any hit hard enough to crack it we would have noticed. We thought of maybe the dog, but there again we feel like we would have heard it(he's only ever in the bed with us).
I looked around and couldn't find anything that would have hit it, but also don't know where it would have come from.
First of all, could something like this be caused from thermal expansion or the like? It's been hovering with highs in the 20s and and 30s the last few days, and this side does get morning sun, but that seems strange to me.
Second, I have a call in to a local glass shop to come look at it, but does anyone know if it might be possible to replace the pane without replacing the entire sash? It's a Reliance brand window that's probably not 4 years old (she bought the house in the fall of 2017, and things like the windows were fitted a few months before she bought it).
Also, can anyone suggest anything besides shrink wrapping to at least keep it insulated and contain glass until we do get this fixed? I'd like to avoid the old cardboard in the window look, but will if it's the only option.
