At BPro Windows & Doors, we provide architects, developers, and building professionals in the Philadelphia region with direct access to a curated portfolio of premium custom window systems, engineered by Cortizo — a leading European aluminium systems manufacturer. Our offering is built for projects that demand uncompromising performance, design flexibility, and technical precision. Every system in our catalogue is certified to the highest international standards, featuring thermally broken aluminium profiles, advanced glazing configurations, and precision hardware — delivering superior energy efficiency, acoustic comfort, and longterm durability across a wide range of building typologies.

Our window systems span a complete series hierarchy — from the highrated COR60 and COR70 lines to the thermally elite COR80 Industrial and Passive Housecertified variants — covering a broad spectrum of performance classes, profile depths, and glazing capacities. Each series supports multiple opening configurations, including tiltandturn, sidehung, hopper, and fixed inoperable units, as well as bespoke largeformat solutions. This gives you the freedom to specify the ideal system for each façade orientation, occupancy zone, and aesthetic requirement — whether for multifamily residential towers, mixeduse developments, or highend singlefamily commissions.

Every window we supply is fully customengineered — manufactured to your exact dimensional specifications, structural load requirements, thermal targets, finish palettes, and hardware selections. With independent test ratings reaching AAMA AWPG80, Uvalues as low as 0.15, STC ratings up to 46 dB, and sash sizes spanning up to 59″ × 102″, our systems represent the top tier of what aluminium fenestration can achieve in contemporary construction. For architects and developers, this means predictable performance, streamlined specification, and a reliable partner from design development through to installation.

Our systems are also engineered to meet the stringent requirements of California Title 24, Part 6 — the Building Energy Efficiency Standards (Energy Code) . Title 24 sets comprehensive energyefficiency regulations for fenestration products, requiring windows and doors to meet specific maximum Ufactor and solar heat gain coefficient (SHGC) limits that vary across California’s 16 climate zones . With the 2025 code update now in effect as of January 1, 2026 , prescriptive Ufactor requirements for window assemblies have been tightened — reaching as low as 0.27 in most climate zones , with a mandatory maximum Ufactor of 0.40 . Our highperformance glazing options, including double and triplepane configurations with lowE coatings, consistently deliver the thermal and solar control performance needed for Title 24 compliance, helping your projects move smoothly through plan review and field verification without costly lastminute redesigns . Whether your project is in California or any other jurisdiction with rigorous energy codes, our systems are ready to perform.

While we are equally committed to serving discerning homeowners seeking the best in replacement and custom windows, our primary focus is partnering with design and construction professionals at the project planning stage — offering technical consultations, BIMready data, and projectspecific performance modelling to ensure your vision is realised without compromise. Contact our technical team for a complimentary specification review and let us help you select the optimal system for your next project.
