The heart of the Preservation platform is Origin II™ premium vinyl resin. This advanced vinyl is rugged, durable, and virtually maintenance-free. The material’s low thermal conductivity makes it the perfect choice for window manufacturing. It assures that Preservation Windows will never rot, peel, blister, swell, or deteriorate from corrosion or pitting. Preservation’s Origin II vinyl also features through-and-through color compounding, so your windows will never require staining or painting. And, Preservation utilizes natural warm white and taupe for its base vinyl color.


Every sash and masterframe corner of the Preservation Window features IntegraWeld Fusion Welding, a technologically advanced method of construction that delivers superior strength.  The IntegraWeld method produces full-contact welding points, and does not require below-the-face flash clean up. The result is maximum strength welding with a clean low-spread finished appearance. And, unlike mechanically fastened windows, Preservation Window corners will never work loose, or leak air or water.


Preservation Double-Hung, Sliding, and Casement Windows feature a beveled exterior masterframe. This masterframe design helps the Preservation Window accommodate differing installation methods and architectural styles. It helps to ensure that every Preservation Window installation will look and perform great, now and for generations to come.


Our double-hung and sliding windows feature Maxum33™ fiberglass sash meeting rail reinforcements. Maxum33 adds extra strength to the sash meeting rails to help prevent flexing during heavy winds.


The premium vinyl resin used in the construction of Preservation Windows provides superior energy efficiency. But we’ve taken thermal performance even further by incorporating Progressive Efficiency high-density carbonized polystyrene insulation into both the sash and masterframe of our windows. Preservation’s insulation is also pre-expanded to eliminate the inconsistencies found with some insulating methods.


Our double-hung windows feature a TrueCapture™ sloped sill. This sill design incorporates the elegant look of a traditional sloped sill with the energy-efficient properties of a capture sill. The result is a great-looking window that is better able to withstand harsh elements.


Our double-hung windows feature the EvenForce™ block and tackle balance system. This system ensures smooth and easy sash opening and closing and has been rigorously tested for decades of operation.


BetterVue® screens do for your window what high-definition technology has done for television: it maximizes the view by making it sharper and more brilliant. Better airflow, a clearer view, and superior insect protection versus standard fiberglass screens.
