Q: What are extruded solutions?
A: Extruded solutions are custom-shaped materials—such as vinyl frames, window spacers, and sealants—created by pushing polymers, metals, or composites through a die. They provide durable, efficient, and tailored components for windows, doors, and solar applications.
-
Q: What is a warm-edge spacer and why is it important?
A: A warm-edge spacer separates glass panes in insulating glass (IG) units. Unlike traditional aluminum spacers, warm-edge spacers improve thermal efficiency, reduce condensation, and extend the life of IG windows.
-
Q: Why choose vinyl extrusions for windows and doors?
A: Vinyl extrusions are durable, low-maintenance, and energy-efficient. They offer flexibility in design and are proven to perform well in both residential and commercial environments.
-
Q: How do sealants improve window and solar performance?
A: High-performance sealants protect against moisture, air, and energy loss. In solar panels, specialized sealants prevent moisture ingress that could cause premature power degradation.
-
Q: Does Quanex offer custom extrusion capabilities?
A: Yes. Quanex provides fully customized extrusion services using metals, polymers, and composites. From concept to final production, we engineer solutions tailored to your exact performance and application requirements.
