Yes, there is a difference. As a rule, replaced windows are of higher quality than newly built windows. This is due to the fact that builders of new houses are eager to reduce costs, and therefore choose doors and windows with the least advantages – energy efficiency, warranty period, quality of materials. The warranty on new windows is 2 years after replacement, while the warranty on replacement windows lasts up to 20 years or longer. All HTR Windows and Doors products come with a comprehensive warranty system of up to 30 years.
