Pella Commercial aluminum-clad wood fixed frames are available for entrance doors and fixed windows (including storefronts, ribbon applications, and window walls) at street level. They offer the warmth of wood interiors and are more economical than solid aluminum. The aluminum-clad wood windows, with boldly articulated clad fixed frames, create shadow lines inside and out and have a variety of exterior cladding color options. Their wood interiors can be repainted or restained, according to design needs. The company’s commercial design team works with customers to develop custom solutions that meet performance and load requirements.
