Just a quick post today. Did you know the average lifespan of an insulated glass unit (IGU) - a double pane window - is 15 to 30 years. Some can last longer, some can fail earlier. That doesn't take into account breakages or other damage. That's why most window companies offer a 5-10 year warranty on their IGUs. Why is it, then, that we offer a lifetime warranty? Check back tomorrow, and I'll go into the details!
