Preservation Window Features & Benefits
Origin II™ Vinyl Technology
The heart of the Preservation platform is Origin II™ premium vinyl resin. This advanced vinyl compound is rugged, durable, and virtually maintenance-free. The material's low thermal conductivity makes it the perfect choice for window manufacturing.
IntegraWeld Fusion Welding
Every sash and masterframe corner of the Preservation Window features IntegraWeld Fusion Welding, a technologically advanced method that produces full-contact welding points, for superior strength and a clean finished look.
The beveled exterior masterframe on Preservation Double-Hung, Sliding and Casement Windows is precision-engineered to ensure that every installation will look great and perform great for generations to come.
Maxum33™ Fiberglass Sash Reinforcement
The Maxum33 fiberglass sash reinforcement in Preservation Double-Hung and Sliding Windows adds extra strength to the sash meeting rails to help prevent flexing during heavy winds.
ProgressiveEfficiency Sash and Masterframe Insulation
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.
TrueCapture™ Sloped Sill
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.
EvenForce™ Balance System
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: they maximize the view by making it sharper and more brilliant. You’ll have better airflow, a clearer view and superior insect protection versus standard fiberglass screens.
