Explore our NFRC-tested, AAMA-certified aluminum hinged exterior casement doors and high-performance window platforms manufactured for immediate job site delivery across Greater Chicago.
By bypassing middleman markups and shipping direct from our state-of-the-art aluminum extrusion and assembly facilities, we deliver commercial-grade exterior hinged casement doors that exceed local Cook County energy codes.
Deep-dive technical insights into engineering fenestration systems built to endure Lake Michigan’s harsh atmospheric stress, extreme freeze-thaw cycles, and heavy wind-driven snow loads.
Standard aluminum is highly conductive. Our hinged exterior casement doors incorporate 24mm to 34mm multi-cavity Polyamide (PA66GF25) thermal struts. This structural barrier breaks conductive paths, preventing interior condensation frost during Chicago winters (-15°F ambient design temp) and maintaining total HVAC efficiency.
Continuous EPDM gaskets coupled with vulcanized corner boots deliver exceptional air infiltration resistance (<0.10 cfm/ft² under ASTM E283) and water penetration resistance up to 750 Pa (ASTM E331). Wind pressures blowing off Lake Michigan are deflected through engineered pressure-equalized weep channels.
For large hinged entrance and patio doors, perimeter security is paramount. We integrate heavy-duty hardware systems from G-U (Gretsch-Unitas), Siegenia, and Kinlong. Stainless steel shoot-bolts anchor the leaf at 4 to 6 points simultaneously, delivering RC2/RC3 burglar protection alongside forced-entry deterrence.
Review how our structural factory configurations compare against minimum Illinois Energy Conservation Code (IECC) requirements.
| Performance Metric | Chicago IECC Code Minimum | Our Standard Double Glazed | Our High-Performance Triple Glazed |
|---|---|---|---|
| Overall U-Factor (BTU/h·ft²·°F) | ≤ 0.30 | 0.24 - 0.26 | 0.16 - 0.19 |
| Solar Heat Gain Coefficient (SHGC) | Determined by orientation (~0.40) | 0.28 (Low-E 270) | 0.22 (Low-E 366 + Argon) |
| Air Leakage Rating (ASTM E283) | ≤ 0.30 cfm/ft² | 0.08 cfm/ft² | < 0.03 cfm/ft² |
| Structural Design Pressure (DP) | DP 35 (Zone dependent) | DP 50 / 50 psf | DP 70 to DP 90 / Heavy Wind |
| Acoustic Attenuation (STC Rating) | Standard (28-30 STC) | 34 STC | 38 - 43 STC (Laminated IGU) |
From historic brownstone rehabilitations in Gold Coast to modern luxury lakefront construction in Lincoln Park, our factory delivers customized profile geometries to fit every architectural vernacular.
Historic Chicago masonry demands specialized exterior trim profiles, custom sub-frames, and simulated divided lites (SDL). Our hinged casement doors provide authentic period aesthetics while hiding modern 3-layer thermal break cores within narrow 67mm sightlines.
Properties in Evanston, Lake Forest, and Winnetka experience persistent, corrosive lakefront moisture and severe wind pressure. We utilize AAMA 2605 powder coatings and marine-grade 316 stainless steel hinges to guarantee zero finish degradation and smooth swing operation.
Multi-family podiums and commercial storefronts require high design pressure ratings and robust acoustic isolation against urban transit noise (CTA elevated lines). Our heavy-duty 86 series casement doors offer acoustically dampening laminated glass configurations up to 43 dB STC.
Architects and structural engineers in Illinois are shifting away from traditional wood cladding and vinyl in favor of high-performance thermal break aluminum for five structural and financial reasons.
Modern Chicago architecture emphasizes floor-to-ceiling daylighting. Because aluminum possesses significantly higher flexural strength than vinyl or fiberglass, sash frames remain rigid even at heights exceeding 10 feet (3.0m). This allows specifiers to maximize daylight area without sacrificing structural wind load integrity during storm season.
Wood-clad exterior hinged doors warp and rot over time under Chicago’s rapid freeze-thaw transitions. High-tensile 6063-T6 aluminum profiles with fluorocarbon anodized or powder-coated finishes eliminate maintenance costs, resisting salt air, frost heave, UV breakdown, and color fading over a 30+ year service life.
With energy codes becoming stricter across Illinois, architects are specifying spectrally selective triple-silver Low-E glass coatings (e.g., Cardinal 366). Combined with 90% argon gas fill and warm-edge Technoform spacers, these units drastically curb HVAC heat loss during severe polar vortex events.
Industrial chic and modern farmhouse design trends have made Matte Black (RAL 9005) and Dark Bronze anodized finishes dominant choices in Chicago residential developments. Our direct factory powder-coating line provides exact color matching with AAMA 2604/2605 certifications.
Partnering with a dedicated OEM factory gives commercial contractors, fenestration importers, and luxury home builders a competitive advantage in lead times, quality control, and custom sizing flexibility.
We do not lock clients into standard size tables. Every opening is custom-cut to your architectural opening schedule. Our engineering team provides stamped shop drawings, section views, and anchoring schedules for local Chicago building permit submissions.
All units are packed in reinforced steel A-frame crates with foam edge protectors and waterproof heat-shrink wrap. Shipments arrive fully bar-coded and sorted by room/elevation for efficient job-site distribution across Cook, Lake, and DuPage counties.
Our profile lines undergo rigorous third-party physical testing by Intertek. Reports confirm air permeability, structural load resistance, water tightness, thermal transmittance, and forced entry resistance compliant with NFRC, NAFS, and AS2047 international standards.

Yes. The City of Chicago enforces the Illinois Energy Conservation Code (IECC). Our thermal break casement doors, when ordered with double Low-E argon or triple-pane glazed assemblies, deliver total U-Factors ranging from 0.18 to 0.26 BTU/h·ft²·°F, easily surpassing the local IECC requirement of ≤0.30.
Production typically takes 25 to 30 days following CAD shop-drawing approval. Ocean transit from factory to the Port of Chicago or local rail ramps takes approximately 22 to 28 days. Total door-to-jobsite delivery timeframe is generally 7 to 9 weeks.
Our heavy-duty hinged exterior doors are structurally engineered for Design Pressures up to DP70 or DP90. When swung outward into the frame, high winds off Lake Michigan press the sash tighter against the EPDM triple gaskets, strengthening the air and water seal.
Absolutely. Every door system is custom fabricated to your exact rough opening schedule. We offer standard RAL powder-coated finishes, anodized metallic options, dual-color frames (different interior/exterior finishes), and textured wood-grain architectural coatings.
We standardize on premium, field-tested European hardware brands including G-U (Germany), Siegenia, Hoppe, and Kinlong. Hardware options include concealed multi-point locking gear, 3D adjustable flag hinges, and ADA-compliant low-profile thresholds.
Our insulated glass units (IGUs) feature dual or triple tempered safety glass panes separated by warm-edge Technoform spacers. The internal chambers are injected with 90%+ pure argon gas and sealed with double-butyl structural silicone to eliminate thermal transfer.
