Norstar Windows & Doors Ltd. manufactures heavy-duty commercial entrance doors and storefront framing engineered to withstand demanding foot traffic and harsh environmental conditions.
Extruded from high-strength 6063-T6 architectural aluminum alloy, our 4 1/2” deep storefront systems provide contractors, developers, and architects with structural integrity, crisp site lines, and versatile performance configurations:
Every component in the Series 1450 and Series 2500 system is fabricated to rigorous Canadian and North American architectural standards (AAMA/CSA).
Extruded, reinforced welded aluminum profiles are integrated into 2500 or 1450 framing. Choose from standard Narrow (2”), Medium (3 1/2”), or Wide (5”) stiles engineered for panic devices, concealed closers, continuous hinges, and electronic strikes.
Factory-glazed with standard 1” clear sealed insulated glass units (IGU). High-performance upgrades include Low-E soft coatings, warm-edge spacers, and Argon gas fill for peak thermal U-values, plus acoustic laminated, tempered, tinted, and reflective architectural glass.
Anodic Oxide treatments in accordance with AAMA specifications, featuring #17 Clear Anodized as standard, alongside champagne, medium bronze, and black anodized. High-durability AAMA 2604/2605 fluoropolymer and thermoset powder coatings available in custom project colors.
Direct architectural comparisons for commercial general contractors, façade consultants, and international procurement teams.

Our welded corner commercial aluminum door slabs are built with heavy 6063-T6 tubular aluminum extrusions. Available in:
• Narrow Stile: 2” vertical stiles for maximum glass vision lines, ideal for boutique commercial storefronts.
• Medium Stile: 3 1/2” vertical stiles offering the optimal balance of rugged strength and glass area for office complexes and busy retail centers.
• Wide Stile: 5” vertical stiles engineered to withstand intense traffic and heavy-duty institutional abuse, school entrances, and public facilities.
Standard glazing pockets support 1” sealed insulated glazing units with silicone-compatible EPDM gaskets. Units can be configured with Low-E soft coats, Argon or Krypton gas insulation, warm-edge structural foam spacers, acoustic PVB/SGP interlayers for sound mitigation, or tempered and spandrel glass configurations.
Norstar applies premium surface treatments that exceed AAMA specifications. Standard finish is #17 Clear Anodized (Class II / Class I). Also available in Champagne, Medium/Dark Bronze, Black Anodized, and high-performance 70% PVDF / Kynar 500 resin fluoropolymer coatings engineered for severe UV and coastal marine exposure.
Series 2500 features a 4 1/2-inch frame depth with an engineered thermal break system to minimize heat conduction and prevent condensation in challenging outdoor climates. Series 1450 is a non-thermally broken 4 1/2-inch extrusion optimized for interior vestibules, commercial partitions, or sheltered exterior facades.
Norstar fabricates commercial doors in Narrow Stile (for maximum visibility in retail environments), Medium Stile (for balanced aesthetics and regular commercial traffic), and Wide Stile (engineered for high-abuse institutional, school, and heavy-use municipal facilities).
Norstar profiles comply with AAMA standards, featuring architectural anodic oxide treatments including standard #17 Clear Anodized, Champagne, Bronze, and Black, as well as ultra-durable AAMA 2604 and 2605 fluoropolymer and architectural powder coatings in custom RAL color codes.
Yes. Our CNC-machined framing and doors can be pre-mortised for standard and heavy-duty architectural hardware, including concealed overhead closers, electronic access strikes, multipoint locking, continuous geared hinges, and ADA-compliant thresholds.
