Good afternoon! We had the glass on our Elmira insert crack last night. It is a good crack, splitting the glass into two pieces, held together only by the glass gasket. There is nothing open today (Sunday) and an emergency call is minimum $500! It is our sole hear source and the temp in the house is 4.5 degrees Celsius .... -30 degrees Celsius outside. Is there anything I can do so we can use the insert until tomorrow evening when hubby can get glass replaced? Someone suggested using the gasket glue on it, but I'm not sure of that. Glue? Aluminum tape? Suggestions? TIA for your advice
