'Interstate' Replacement Windows?
Has anyone heard of Interstate Windows? Apart from the fact that they seem to be out of P.A., I can't find any discussion about them on the internet. We've been pricing some expensive replacement windows, and along came a quote from one company with Interstate (for their CompositeWood collection - composite wood)They're 1/2 the price installed of the better windows we've researched. They are Energy Star qualified and NFRC rated very well, so why can't I find a darn thing about them?
