Duratherm Window Corporation

The Duratherm Difference Every once in a while a company comes along that defines its category. When it comes to high-quality hardwood windows and doors that are customizable and that enhance and enable architects’ designs, Duratherm Window Corporation defines that category and everyone knows it. But as a company, we understand the competition is hard on our heels and that in each year and on every project we have to be better and better. There’s no resting on one's laurels in the window business. Our customers may happily gaze out of our windows in wonder, but all we can think about is how to make windows that meet our customers’ demanding specifications more fully, more beautifully and more affordably. We know that Duratherm windows and doors are not for everyone, but we wish they were. One of our long-term key employees said recently, “If architects and contractors knew what I know about Duratherm, they would never go anywhere else.” That idea, of helping you know what we know, is the purpose to which this site is dedicated.
