Double glazing window seals

Please, please, please, someone (expert hopefully) tell me that the actual seals (ie the black rubber) that are on DG windows are important in helping the sound proofing. You have a seal on the window that opens and another on the casing it shuts against. I live in a country where mumpets build the houses. Both of these window 'seals' are incredibly thin and there is no 'resistance', no 'pressure', no 'seal' when you close the windows and we can still here everything that is going on outside. Yes it is reduced slightly but not enough for having double glazed windows!! And not enough to give you a peaceful nights sleep!! I am several hundred yards away from a fairly busy road and from inside my house I can here all the traffic, every lorry and their air brakes. I could even here someone talking outside of my garden with all the windows shut, blackout curtains and ordinary curtains. I am trying to explain to the window company here, that the windows need to 'seal' when you shut them. I am going out of my tree here. Please help :) Thanks

I have a very similar problem, the seal i have is just a brush type and lets a lot of noise through as well. I started researching this recently, after putting up with the windows for about 5 years, as i noticed the seals on my dads newly installed units provided a much snugger seal.
