Insulating glass is used in residential and commercial construction and has risen steadily over the year to where the majority of all new and renovation construction today includes IG units. IG units not only save monthly heating and cooling costs but they also reduce the initial size and cost of the heating and cooling equipment required on a project.

A combination of Low-E coatings, tinted glasses, reflective coatings, silk-screened patterns, laminated glass products and a wide variety of insulating glass configurations are available to satisfy a wide range of performance and aesthetic requirements.

Midland Glazing Insulating Glass (IG) units are hermetically sealed combinations of two or more sheets of glass separated by a dry airspace, IG units improve thermal performance, significantly reducing heating and air conditioning costs. IG units also reduce interior condensation in cold climate.
