Mezzo’s refined and purposeful design stays true to the classic double-hung style, yet exudes a cool, contemporary elegance with clean lines and crisp corners. The double-hung window is equally loved for its carefree functionality. No need to struggle with hard-to-reach areas. Both sashes tilt in to allow easy cleaning from inside the comfort of your home. Built for everyday wear and tear, the expertly constructed sashes raise and lower easily on a constant force balance system eliminating sash cords, weights and pulleys.

Visually sleek and deceptively strong, Mezzo sliding windows are distinct in their slim silhouette, ample glass area and smooth gliding action. They provide wide-open volume and natural light. Both sashes slide horizontally for easy opening and closing and lift out for convenience cleaning. The heavy-duty construction and weathertight fit ensure excellent performance and protection.

The beauty of our EdgeForce narrowline frame and sashes is subtle and substantial at the same time. The sleek design is visually clean and contemporary, with a larger glass area for exceptional daylighting and outside viewing. And beneath the elegance? Internal chambers are meticulously engineered for structural integrity and enhanced energy efficiency.

CoreFX is a structural component that never quits. This innovative composite reinforcement allows for secure mounting of hardware and the non-conductive material also reduces the transfer of energy for superior thermal performance.
Double-hung base model will automatically be upgraded to ST (steel reinforcement) for all units ordered in excess of 48″ wide or 84″ high.

Stylish and strong, this low-profile secure locking hardware features an indicator that tells you if your windows are left unlocked. But the true beauty of Defense-Tek is its end-of-throw cam shift locking action, expertly constructed for increased protection.

Forecaster elevates both the appearance and performance of Mezzo Windows with its smooth, uniform design. The true sloped sill is expertly crafted to provide a highly efficient drainage system that promotes water runoff without the use of weep holes.
For larger size windows or to meet specific DP/PG ratings, optional weeps/performance package must be ordered.

The benefits distinction here is three-fold: protection from air and water infiltration, increased structural stability and enhanced beauty. The integrated telescoping sill dam effortlessly blends strength with style.

When extreme wind and weather hit your home, Gatekeeper stands strong. Traditional sloped sill designs can allow the sash to bow during powerful winds, but with Gatekeeper interlocking sash-to-sill technology, the sash is channeled firmly into the window frame for a unified wall of strength. Combined with three layers of weatherstripping, Gatekeeper delivers unmatched protection, as well as peace of mind.

Improved form and functionality is the focus of our Ocular screen bulb seal. The compression bulb aids in the installation and removal of the extruded aluminum screen. The snug fit also eliminates light penetration between the screen and frame and helps block insect access.
