So far this has been a great easy experience. The sales person came out he was very knowledgeable and I can say I really did not want to hear the whole spiel. I just wanted a quote. Well I let him do his spiel and one thing he did was show me the difference in the heat transfer of their window versus others. Since that was the issue that I was dealing with I was extremely impressed. I feel sure now it will make a huge difference in the temperature of the rooms in the house. That demonstration was the actual clincher. So make sure you listen to the spiel and you might just hear the answer to the questions you have in your head going into it.
