NCPTT is conducting a comparative study of commercially available window glazing compounds (also known as “window putty”). There are many different products on the market and, while we would like to include all of them, we must limit the study to the top six compounds. Help us determine the most commonly used glazing compounds by taking our very brief survey.

UPDATE: This survey is now complete. Thank you for your participation.

Research findings will be made available to the public on our website once our analysis is complete.
