New double glazed windows ... condensation inside

if the window had a 30mm gap and they used a frame extender, then they measured the window wrong. If this is the one they are taking out I would hope they have re measured and remade the window. Condensation on the inside of the window is definitely related to internal humidity and surface temperature of the glass.

No this isn't the one they are taking out.  I dread to think what is behind the trims of the  window they are taking out I didn't see this window go in whereas the lounge and dining room I did and saw the large gap.  Hence the frame extender

Condensation on the inside is nothing to do with the windows. If you have poor ventilation, look into getting a dehumidifier. 

I don't have poor ventilation.  So why am I getting it on one window and not the other.  Same room different products!

Are both windows on the same wall?

When is the condensation occurring, throughout the day or is just when you get up in the morning?

Separate walls downstairs lounge and condensation in the morning

One wall may well be cooler than the other due to it's aspect hence the condensation on that particular window. It may be nearer to the occupants of the lounge during the evening and therefore come into contact with more of the moist air than the other wall.  The point being unless the different windows were on the same wall it's difficult to say if one's performing better than the other, or if one is somehow faulty.

I fully agree with this. Our lounge and kitchen have two windows each on different elevations of the house. The windows were all made by the same company to the same specification and were all installed at the same time. Some mornings  we get condensation on the outside of the windows (not the inside) which can affect one window in each room but not the other.

Condensation on the inside of the windows points squarely at a lack of adequate ventilation despite what the OP would like to believe.

Both products on different walls.  We've had condensation on the outside on both products.  I'm not to worried about this as this proves the windows are doing there job and working.  I do have adequate ventilation this is the first thing the installers said when the problem first become!  Having worked for a major double glazing company for several years help running the service department, I do have a slight insight to what I'm talking about.  Yes, I did have loads of angry customers and the majority of problems was down to bad fitting/mis measured products! But products have changed rapidly since I worked in the industry so that's why I'm asking the question
