Durability

Kelly Window Systems is determined to produce products that last.

Whether you are purchasing one of our ALUMINUM WINDOW or DOOR systems, or one of our all VINYL lines, you are guaranteed to be getting a product that will perform and keep on performing for years to come.

Our ALUMINUM line of products is constructed with 6063T5 Thermal Barrier Extrusions. During manufacturing all the mechanical joints are telescoped together and securely fastened by two stainless steel screws providing superior strength and durability.

Our VINYL line of windows is produced with Ridged PVC extrusions that are designed to meet and exceed the requirements of the nationally recognized AAMA standards.

All of the products we manufacture have been physically tested for air and water infiltration as well as structural limitations assuring your safety and comfort.

We would be happy to share all of our test results with you so please contact us for more information.
