Need advice on cracked window asap
I know nothing about windows... One of my roommates and I got back to our apartment at school after being gone for the weekend, and there is a large diagonal crack from one side of the window to the other in our living room. 2 other roommates were here this weekend and seem to know nothing about it.
My question is--what could have caused this crack?? It has gotten very cold in the past few days, could that cause a crack? There are 2 layers to the window, and it is the inside pane that is cracked. Would something have had to have hit the window, or could it just crack due to the cold??
