Calling The USA!

I've recently acquired more followers on Twitter from America, and so I thought it would be nice to hear about the window and doors industry from over the pond. It would be interesting to know if there is an emphasis on energy efficiency like there is over here, if PVCu is making much of an impact in the US yet. Those sorts of things.

If your are from America, email me at: glazingblogger@googlemail.com and I'll put your message on here as a guest post.
