proud partnership
We're proud to partner with the Window Preservation Standards Collaborative (WPSC) and the work they are doing to promote the education and standards used in the window restoration trade.
The Start
In the Fall of 2010 several window specialists realized the time was right to create national standards for the repair and weatherization of old and historic windows.
The Window Preservation Standards Collaborative (WPSC) now includes over one hundred and fifty other window specialists from across the country and in Canada.
Why Now?
There is an immediate need for standards that include well researched energy data as well as a catalog of proven methods used to repair and restore historic windows.
We cannot wait for years or decades for a standard to “evolve” since the replacement window industry is now actively destroying millions of historic and perfectly functional old windows every month. Obviously there is nothing green or environmentally sound about this tragedy.
Urgent Action
The quicker we put this effort into play, the less time the replacement window industry has to spend their tens of millions in marketing money to discredit this critical and objective effort.
The window replacement industry’s aggressive marketing has bamboozled homeowners, contractors and property developers into believing window replacement is the only option.
Just because they claim their products are superior does not make it true. Act now or lose your historic windows forever.
New Hope
Over the past 30 years, a handful of experts have been repairing, restoring, and weatherizing historic windows—often fighting to keep them from being replaced. Today, the tide has turned. From the National Trust to local preservation groups, saving historic windows is now a priority.
Yet, many architects, developers, and tradespeople still lack clear standards and data for proper restoration. Our mission is to change that—by providing sustainable restoration guidelines and proven energy-performance testing for historic windows.
The Book
In the summer of 2013 the National Window Preservation Standards book was published and available for purchase. It catalogs specific methods for the assessment, maintenance, repair, preservation and weatherization of older and historic windows.
Many detailed methods, procedures and materials will be included, as well as basic strategies for saving older and historic windows.
National Window Preservation Summit,
July 26-28, 2011
WPSC hosted the first National Window Preservation Summit at Pine Mountain Settlement School in Kentucky—a landmark research initiative. Founders demonstrated restoration and weatherization methods daily, followed by adviser feedback sessions.
Energy testing measured the efficiency of each method, refined based on expert recommendations. The Summit brought together 35 leading advisers from across the country and 15 invited observers.
Fundraising
The WPSC is raising money support this project through bi-annual Summit gathers, silent auctions, sale of the first standards book and donations from the community and restoration trades people. Every donation gets us one step closer to publication of the second edition of the Window Preservation Standards book.
