When you look at aluminum-clad windows, you will learn that some are clad with roll-form aluminum, while others are clad with extruded aluminum. What’s the difference? Which is better? You should not make such a large investment in your home or business without understanding exactly what you are getting. At Clevernest, we enjoy helping our customers understand the products and the process of installation. We believe that educated consumers will recognize the quality of our product over many of our competitors and the value of our pricing relative to the quality.
