The key to maintaining an external insulating finishing system is to periodically inspect and repair any areas that may be compromised. This includes checking the walls, windows, doors, and other points of entry for damage or deterioration due to weathering or wear. Additionally, it is important to replace deteriorating insulation materials with new ones as needed. It may also be necessary to periodically clean the outside of the building, as dirt and debris can reduce the efficiency of an insulation system. Finally, it is important to ensure that all seals and connections remain secure to prevent air leakage. With proper maintenance, an external insulating finishing system will help reduce your energy bills and maintain a comfortable environment indoors.
