Has anyone purchased safe and sound windows from Anglian windows?

Posted 20th Jun 2015Available: National
I had a contract with Anglian windows for triple glazing, but was phoned today to say they had made a mistake and can't offer triple glazing on the oak finish and they would upgrade us to there safe and sound glass free of charge. Has anyone had this installed in there home and does it help with reducing noise level?

thanks in advance
