Double Hung windows have two operable parts— the top sash and the bottom sash. They are both able to open to provide ventilation and tilt for easy operation and cleaning.

• Two multi-function, heavy duty die cast locks activate the integrated tilt feature and are engineered for easy cleaning while eliminating the need for unsightly tilt latches.

• Neopor ® rigid thermal insulation contains heat reflecting graphite particles to improve thermal efficiency.

• Cove-crafted interior sash moulding combined with equal sight lines create an attractive traditional window styling.

• IdeaSeal™ triple protection weather seal keeps the indoor and outdoor environments separate with an integral interlock, sill compression seal, and multiple rows of weatherstripping.

• Dual Function partitioned sloped sill forms a negative pressure pocket that keeps sashes securely in place and water flowing away from your home, even in the most adverse weather conditions.

• Biomaxx advanced composite locks and keepers are 50% stronger than typical die-cast hardware while remaining lead-free, color-true without fading, warping or chipping.

• Shadow grooved sash welds replicate the classic look of mitered wood corners.

*Features vary depending on which window model collection is selected.
