Units can and will eventually go bad and to remove the fog efficiently from your window would require a brand new sealed pane of glass. Your glass can go bad from a variety of reasons such as: deterioration, mistakes made from the installation or simply old age (Your thermal pane units typically can last between 15-25 years).
A broken seal on your window can reduce the insulating capabilities and can potentially make your heating bills go up. Do you see fog, condensation, moisture or dampness in between the panes of glass? We provide complete repair services either on site or in store for thermal pane glass. If the glass in your thermals have started to “fog” up, you may need to replace your sealed glass unit.
