Having recently moved to a house with PVCu double gazing I have noticed
how stuffy the environment inside the house is now that the windows are

stale the air seems. My previous home was quite draughty.

Must be quite old DG.

All modern stuff has (adjustable) vents above the
windows.

The UPVC DG in my last house was installed in 2000 - not old in my book,
it didn't have trickle vents.
