Hi Paul, Just writing to commend your work. Aside from the huge reduction in noise I have now, I think the bigger thing is how much warmer the apartment is now.  I walked in after dropping Cameron home tonight and was blown away by how warm it is inside. Obviously I was losing a lot of heat through the single windows. Now I am clearly retaining a lot more of it. Very happy with the work you have done and also your excellent service. I just wish I could keep living in it! Ha
