Condensation in Triple Glazing

Condensation in triple glazing and double glazing can occur both on the inside and the outside of the window. Older double glazing units were particularly susceptible to condensation appearing; nowadays modern triple glazing systems have been design to combat condensation. While condensation cannot be ever fully prevented, installing triple glazing to replace double glazing does help the matter.

Outside of glass

Condensation in triple glazing may appear on the outside of the glass; this has a lot to do with the energy efficiency of the window and the fact it is designed to reduce heat loss. The insulating properties of triple glazing result in the outer layer of glass, becoming much cooler than that of the double or single glazing. If the outer glass temperature sinks below the temperature in the air and the humidity on the high then condensation will appear on the glass. This can be seen happening in the early hours of the morning when the temperature begins to rise; condensation is more recognisable during autumn months, and August, September and October tend to see a lot of condensation.
Condensation on the outside of the glass is not anything to worry about, it is a regular occurrence and in fact shows that the window has good insulating properties and is doing its job. 

Inside of glass

If condensation in triple glazing has appeared on the inside of the glass, it normally suggests that the window has poor insulation properties. This form of condensation is usually found in older windows, during winter months and is rare in triple glazing. Poor insulating capabilities mean that the glass will get colder than the room itself, hot air form the room hits the cold glass and condensation appears.

There are other ways that condensation in triple glazing appears on the inside of the glass, these can include, bad ventilation systems and very high humidity. Curtains and blinds can also be a factor in condensation building up; curtains and blind can prevent air close to the window from circulating resulting in condensation.

Whereas condensation on the outside of a window is nothing to worry about, condensation on the inside is. First of all it indicates that the window is not providing proper insulation and may have a break in the seal. Secondly if condensation is left for a prolonged period it can be harmful to the window as triple glazing units are not designed to prevent moisture from the inside.

Repair

If condensation in triple glazing has appeared on the inside of the glass, it is advisable to contact the manufacturer or a repair company as soon as possible; acting quick may prevent the window from needing replacement. Manufacturers generally provide a ten year guarantee on their triple glazing units, and it will cover any fails in the system. Trained repair companies will be able to remove the condensation and reseal the unit if caught early.

Companies can be easily found on the internet and through local directories.
