Condensation

[rosiew]

Since having Cavity Wall Insulation installed my windows are constantly covered in condensation even if the windows are opened when i am cooking, not only the kitchen window but all the downstairs windows. Would a humidifier help.
Thanks in advance

Most certainly.

This is not normally an effect of having cavity insulation. One must suspect that air bricks linking inside to outside have been filled with the foam. They shouldn't have been.
