Window Preservation Summit II

The National Window Preservation Standards Collaborative

Window Preservation Summit II

The Business of Window Preservation

The business of preserving & weatherizing old and historic windows is emerging as one of the fastest growing segments of the historic preservation, artisan trades industry. The national Window Preservation Standards Collaborative (WPSC) is a modern day artisan trades guild with over 200 participants. The WPSC has taken on the task of dispelling the myths perpetrated by the replacement window industry through their disingenuous marketing.

Today there are window preservation companies and individual artisans in every state in America. Yet, for over 50 years the disposable replacement window industry has owned the narrative about windows. They have replaced as much as 65% of America’s historic windows with unsustainable, unrepairable and substandard windows.

If we are to preserve the remaining 35% of old and historic windows, we need to take our businesses to the next level. It’s time to take the narrative back and to do so we need to learn from each other how to run our businesses effectively.

In 2011 the WPSC held the first National Window Preservation Summit at the Pine Mountain Settlement School in Pine Mountain, Kentucky in the heart of the Appalachian Mountains. The results were astounding. We established with practical work and scientific testing that weatherized old and historic, wooden double hung and steel casement windows exceed the 2009 & 2012 International Energy & Conservation Codes for air infiltration. The results were published in the Window Preservation Standards book in 2013, along with peer reviewed best practices for the preservation and weatherization of historic windows.

  • The business of window preservation
