Foggy & Broken Insulated Glass (IGU) Replacement
Fog or moisture between the panes means the seal of your insulated glass unit has failed and its insulating value is gone. CBE Glass measures, orders and replaces failed or broken insulated glass units in commercial windows, storefronts and curtain wall, keeping your existing frames.

Why replace failed insulated glass
Failed units raise heating and cooling costs, look neglected and can hide further damage. Replacing only the glass unit is far less expensive than replacing the whole window, and it is the perfect moment to upgrade to higher-performance low-E glass.
