I've recently had new windows fitted throughout the house as the others were like 30 years old. The new ones legally (I believe) have to have vents on them we didn't have a choice. Now when I got to bed I can hear outside noise that I never heard with the old windows. I'm assuming it's because of the vents. I keep getting out of bed because I think I've left window open. I'm so annoyed that I've spent so much and I'm so disappointed in them. Has anyone else found this with new windows?
