In these situations, replacing the sealed unit will not suffice to restore the window's full value of insulation. It will only delay the need to replace the window.

Installing new aluminum cladding on top of wooden frames is a good option for retrofitting. This shields the wood from elements and prevents it from getting rotten. This could be a problem with older windows.

Recyclers buy scrap sealed units and then strip them down to their component parts, including the copper windings that comprise the core of the motor. The windings are then reused to create new sealed units as well as other products. Recycling these units helps avoid landfill contamination, stop gas leakage and saves natural resources and money.

4. Maintenance
