Hey, guys, I am in the midst of a home renovation right now. The house that I live in is really old and the windows are all drafty. I am thinking of getting it replaced. While doing a bit of research online I came across some energy efficient windows that not only helps in reducing draft but are durable as well. Most of them are vinyl. Do you guys have energy efficient windows at home? If you don't, then can you tell me whether there are any other windows that are equally good. I am doing a major renovation right now so I am looking for windows that lasts a long time. If you guys could give me any suggestions on this, it would be great.Tia.
