I have just had new double glazing installed, but two of the windows are misting up overnight on the outside. I am not sure why this is happening.
The misting is not inbetween the glass but actually on the outside of the glass.
Does anyone have any ideas please
I am very unsure but I am thinking it might be like dew on the grass. It may only be misting because of the change of the outside air temp. Good chance the whole side of the house does this but you can only see this on the window. Are both windows on the same side of the house causing the shade to be the same?
Hi thanks for replying
Yes both windows are on the same side of the house but there is no grass.
I can see that it would be change of temp but the upstairs windows which have been installed for a long time are not affected.
The dew it new related to the grass it is just a common place to find it. I believe the dew would be more common closer to ground level. The upstairs windows probably have more breeze and light hitting them in the morning. I would be still be curious to see if any one else has any theorys or reasons.
