Performance
Telescoping welded sill detail improves performance and structural rigidity. Our high-performance sloped sills are made from a single extrusion, which makes them stronger and more durable. Multi-chambered extrusions and storm interlock improve energy efficiency and structural performance

Easy Operation
Constant force balances provides extra lift assistance for easy operation, while our tilt latches allow both sashes to tilt in for easy cleaning from the inside.

Strong Seal
The integrated full-perimeter nailing fin and triple weather seal ensure a weathertight seal to reduce drafts and protect against leaks.

Continuous Head & Sill
Envision Double-Hung windows have a continuous head and sill on multiple wide units up to eight feet wide. This provides clean sight lines, and ensures there’s more visible glass to enjoy.

Full Screens
Open both the top and bottom sashes to allow for ventilation, while still keeping bugs out with full screens, which come standard on Envision Double Hung windows.

Ultimate Energy Efficiency
Want to achieve the ultimate in energy savings? Our Envision Double-Hung windows are available with triple-pane glass, which will qualify for the new Energy Star® “Most Efficient” product category.
