At B-Pro Windows & Doors, we supply Philadelphia homeowners, architects, and commercial clients with access to an exclusive selection of premium custom window systems, engineered by Cortizo — one of Europe’s most trusted aluminum systems manufacturers. Every window in our catalog is built to the highest international performance standards, combining thermally broken aluminum profiles, advanced glazing technology, and precision engineering to deliver exceptional comfort, energy efficiency, and lasting architectural refinement.

Our window systems are available across a comprehensive range of series — from the robust, high-rated COR60 and COR70 lines to the thermally elite COR80 Industrial — covering a wide spectrum of performance classifications, profile depths, and glazing capacities. Each system supports multiple opening configurations including tilt & turn, side-hung, hopper, and fixed inoperable, giving you the flexibility to specify the right solution for every room and every exposure. Whether your project calls for standard residential replacement windows or large-format custom units with triple glazing and concealed hardware, we have a system that fits.

Every window we supply is fully custom — specified to your exact dimensions, performance requirements, finish preferences, and hardware selections. With AAMA ratings reaching AW-PG80, U-Values as low as 0.15, STC ratings up to 46 dB, and sash dimensions spanning up to 59″ × 102″, our window systems represent the upper tier of what residential aluminum construction can achieve. Contact our team for a complimentary consultation and let us help you identify the right system for your home or project.
