HIGH-PERFORMANCE VINYL REPLACEMENT WINDOWS

Preservation High-Performance Windows encompass all of the hallmarks of exceptional window design - unsurpassed quality, functional beauty and maintenance-freedom - in custom styles to masterfully complement your home's architecture. Plus, Preservation Windows are designed to help reduce heating and cooling costs and make your home more comfortable.

WINDOWS PERFORMANCE RESULTS

✔ Pass Air infiltration
✔ DP55 Water resistance
✔ DP65 Structural load

Preservation Windows are certified by subjecting them to the battery of ASTM (American Society for Testing and Materials) tests for air infiltration, water infiltration, and structural performance. These tests are part of the accepted industry standard for windows.* Independent third parties, from an AAMA (American Architectural Manufacturers Association) approved testing laboratory, witness all tests. AAMA is a national trade association that establishes voluntary standards for the window and door industry. The AAMA administrator issues the certification.

AIR INFILTRATION

Preservation Windows are tested for air infiltration using the industry's rigorous air infiltration resistance testing procedure. Test ASTM E 283.

WATER RESISTANCE

Preservation Windows are subjected to a driving water spray of five gallons per hour/per square foot (equals rainfall of eight inches per hour) at a simulated wind speed of over 57 mph. Test ASTM E 547.

STRUCTURAL LOAD

Preservation Windows are subjected to interior (negative) and exterior (positive) structural load conditions simulating a wind speed of over 190 mph (the highest ranking on the Hurricane Damage Potential Scale is a Category 5, which is reserved for those hurricanes which exceed 155 mph wind speeds). Test ASTM E 330.

Features and Benefits

ORIGIN II™ VINYL TECHNOLOGY

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.

INTEGRAWELD FUSION WELDING

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.

RENOVATION MASTERFRAME

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.

MAXUM33™ FIBERGLASS SASH REINFORCEMENT

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. 

PROGRESSIVE EFFICIENCY 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. 

PHIFER BETTERVUE®

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.
