1.1.10 Maintenance of wood and aluminium windows frame


Inspect regularly the windows frame and repaint it if there are cracks which can expose the timber or aluminium to moisture which cause corrosion of aluminium or decomposition of the timber. Lubricate and clean hardware components to avoid a faulty closure. Badly maintained windows cause water and air infiltration.


  • Reduce air infiltration

  • Heating and cooling energy are saved

  • The maintenance can be home made

  • Extend the lifetime of the window


  • Depending on climate conditions, it may be necessary more than one maintenance action per year

Economic assessment

Low investment. It depends on the time interval for each maintenance action.
