Hi All, I'd appreciate your thoughts/ experience. The two rooms at the front of the house have big beautiful windows, which is wonderful, but you can really hear the cars as they go past. We're in a conservation area, and willing to pay more to have it look good - what would you recommend? Its also for heat purposes, but realistically mainly for noise proofing. Is there anything out there that effectively cuts the sound whilst still looking nice/ in keeping with an old property?
