After speaking with the Warranty Department, I was informed that the crack in my window (Model 0971 - Casement) was not covered by the warranty, as the warranty does not cover breakage of glass.
The glass cracked however, on day when in Minneapolis it was -20 degrees and I believe there was a defect within the hermetically sealed insulation that failed. The window was only 2 1/2 years old.
I was told by a contractor that warranties from other window companies would cover this circumstance, but Alside did not. Will replace with another company. Their warranty is very poor.
