Easy to Clean


Most of the operating windows available at Window Wire are exceptionally easy clean. On the double hung window for example, both the top and bottom sashes effortlessly tilt in allowing for safe and easy cleaning of the exterior of the windows. If you have grids, they're placed between the two (or three) panes of glass further simplifying the cleaning process. In addition the easy cleaning features, there's virtually no other maintenance required. Simply wipe down the frame with a damp cloth and your new windows will continue to look new for years to come.

Exceptional Comfort


An often overlooked aspect to replacement windows is how easy they are to live with. A houseful of Mezzo windows from Window Wire will make your home substantially quieter. The insulated glass and sealed air chambers not only keep the outside elements out of your home, but also the outside noises. You'll sleep better and can finally relax in peace and quiet (unless you have kids). With the superior insulation properties will help keep your home at a consistant comfortable temperature. The special Low-E coatings on all Window Wire windows, will reduce the sun's ultraviolet and infrared energy which in turn reduces fading to keep your curtains, carpets, and furniture looking new. Lastly, the slimline frame allows for a generous amount of glass and you a better view.

Superior Insulation


The Alside Mezzo, available through Window Wire, is exceptionally well insulated. Argon gas fills the air chamber between two panes of glass counteracting the heat/cold conduction. The gas is held in place with a PPG Intercept Warm Edge Spacer which keeps the edges of the glass warm and reduces condensation problems found with a typical box metal spacer. The glass itself is coated with a Low-E metallic coating which reflects heat back the way it came. The airtight insulation chambers around the perimiter of the frame, further enhance the superior thermal efficiency of the Mezzo. These features and many more come standard on even the "Not Energy Star" rated windows available through Window Wire.
