The cold mornings are rolling in and many homeowners who have had the very latest high performance elitis windows installed, may be encountering an unusual phenomenon.
Condensation on the outside of the glass.
External condensation may occur on the latest energy efficient double glazed windows and demonstrates that the windows are doing a fine job of keeping heat in the building. … The phenomenon is a natural and predictable event caused by the outer pane of the glazing being colder than the glass that it replaced.
You may be asking yourself though, “why didn’t I see this on my old windows?” The reason you didn’t notice this on your previous double-glazed windows was that they weren’t particularly efficient. The sealed glazed units must have been allowing enough heat to escape from inside the house that the outer panes of glass were kept above dew point temperature. Hence no dew formed on them (although it will still have been forming on the outer surfaces of your walls, where you wouldn’t have noticed it).
Once your elitis installer has completed your installation, you will be handed a completion pack which includes a very handy explanation guide regarding external condensation.
So don’t worry. If after your new elitis windows have been installed you experience external condensation, it simply means your elitis windows are performing at their peak.
