This presentation took place during the 2020 Region V Meeting. Window replacements and retrofits represent a significant investment, and, therefore, it is key to decide on the right strategy and to provide the owner with accurate information on performance and options. Before you replace or retrofit windows, many factors need to be carefully evaluated. The most important first step is understanding the owner’s reason for wanting to replace or retrofit windows. For example, if improving sound control is the primary reason, then glass selection for the new window or a retrofit storm sash are the critical factors to consider. If water intrusion is the main complaint, then it is critical to understand whether the water intrusion is related to the window only or the surrounding wall claddings or flashing. The second most important step is evaluating the existing conditions of the windows and its integration and flashing with the surrounding wall claddings. These first two critical steps will then help you advise the owner on appropriate replacement and retrofit strategies and options, which include window types and installation options. This presentation will cover this evaluation, design, and installation process and explain several key energy efficiency upgrades that can be considered at the time of window replacements for low incremental cost. This presentation will also show example case studies of what can go wrong when these steps are not followed.

Learning Objectives:

1. Identify the owner’s reasons for window replacement or retrofit, including whether to address water intrusion, condensation, air leakage, thermal comfort, energy performance, functionality of window sizes, aesthetics, acoustics, or security.
2. Describe the steps in a condition assessment to determine performance of existing windows and the integration with surrounding wall claddings and flashings.
3. Summarize window replacement and retrofit options, including punched windows, ribbon windows, reglazing options, and installation options.
4. Explore with the owner energy efficiency retrofit options for both windows and surrounding claddings that can be performed at the time of window replacement for low incremental cost
