AESTHETICS AND TECHNOLOGY . . . REDEFINED

L.J. Neal & Sons Mezzo window replacement

EdgeForce Narrowline Frame and Sash

The beauty of the EdgeForce narrowline frame and sashes in the Mezzo windows 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. The internal chambers are meticulously engineered for structural integrity and enhanced energy-efficiency that compliments our heat-stopping triple pane in your double-hung window replacement.

CoreFX Composite Reinforcement

CoreFX is a structural component in the Mezzo windows that never quits. This innovative composite reinforcement allows for secure mounting hardware and the nonconductive material also reduces the transfer of energy for superior thermal performance in your double-hung window replacement.

Defense-Tek Secure Locking System

Stylish and strong, this high-profile locking hardware in our Mezzo windows 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 in your double-hung window replacement.

Forecaster True Slope Sill

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 in your double-hung window replacement that promotes water runoff without the use of weep holes.

HP3 Telescoping Sill

The beneficial distinction in Mezzo windows is three-fold: protection from air and water infiltration, increased structural stability and enhanced beauty. The integrated telescopingsill dam effortlessly blends strength with style in every double-hung window replacement.

GateKeeper Sash-to-Sill Interlock

When extreme wind and weather hit your home, Gatekeeper in the Mezzo windows stands strong. A traditional sloped sill design in a double-hung window can allow the sash to bow during powerful winds. But with Gatekeeper interlocking sash-to-sill technology, the sash in our double-hung window replacement 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.

Ocular Screen Bulb Sill

Improved form and functionality is the focus of the Ocular screen bulb seal constructed in our Mezzo windows. The compression bulb aids in the installation and removal of the fully extruded aluminum screen. The snug fit also eliminates light penetration between the screen and double-hung window replacement frame, while helping to block insect access.

Add sophistication to your home with optional grids in your double-hung windows.
