Installation

Overview

Stylish full 3 1/4" depth uPVC fusion welded frame and sashes with a beveled colonial exterior curve that are not only beautiful, but also allow for maximum weld surface resulting in outstanding strength and years of long-lasting performance.

The sill dam wall is mortised into the jamb adding strength and lowering the possibility of leaks that may occur at corner seals.

Eco-Pro double hung features beautifully designed metal handle on the top sash and a fully integrated lift rail on the bottom sash. 

Push button spring-loaded vent latches allow both window sashes to remain partially open for ventilation. Vent latches not available on laminates.

Standard slim profiles sash lock with tamper-resistant cam ensures a much smoother turn and increases the life cycle over traditional locks.

Additional high-density composite reinforcement inside the locking sash makes our windows structurally stronger than others available on the market. 

One-piece sloped sill with double dam leg helps eliminate clogged and frozen weep holes as well as makes windows structurally stronger. This reduces air infiltration and chimney effects drafts.

WOCD latches available as an optional upgrade.  WOCDs add an extra level of safety for you and your family. When activated, the device will allow the window to be opened no more than 4 inches. If you would like to open the window fully, you can deactivate the device and when you close the window the device automatically reactivates. 

Available in White and Almond.
