DIY GLAZING FILM

double glazing film and condensation?
In my home, not all the windows are double glazed. Only 3, and the other 4 are single glazed.
So to save energy I bought and install a kind of double glazing film I found in a DIY store.
Now I think that there is less condensation on those windows but more on the wall and corners inside those rooms.
Can anybody see a reason for this?
Yeah! Your house is damp – somewhere moisture is building up.
Good place to check first is guttering and drainpipes – see if they are blocked up – water will splash and seep into the mortar joints
Next – check the seals on the outside of the windows as they join the bricks.
Do the obvious first and work around. Are the rooms bedrooms – moisture (especially in this weather) from your breath alone can cause damp walls
Water tanks in loft can leak – etc etc etc
You just have to seek I’m afraid
