Level

To make a line or surface horizontal or flat; parallel with the plane of the horizon. No portion of a line or surface is higher than the other.

Low "E" Glass

Glass which is coated by a Low "E" (low-emissivity) coating, The transparent metallic coating is applied to the surface of the glass (soft coat) or applied into the glass during the manufacturing process (hard coat). The Low "E" coating allows short-wave energy to pass through but reflects long-wave infrared energy. The Low "E" coating increases the window's insulating value. In addition, it helps reduce fading of carpeting, furniture and draperies.
