An in-depth analysis of solar heat gain coefficient (SHGC), marine salt-fog corrosion mitigation, structural wind-load resistance, and Title 24 compliance across Bay Area architectural topologies.
San Francisco's unique geographical peninsula position creates extreme thermal variance across its 47 square miles. While neighborhoods such as the Sunset and Richmond districts experience dense marine fog layer penetration, inner bay areas like the Mission District, Noe Valley, and SoMa undergo intense solar irradiance with ambient temperatures spiking up to 25°F higher during peak sun hours. Designing structural sun control solutions, motorized zip screens, and thermally broken acoustic fenestration requires tailored solar heat gain coefficient (SHGC) engineering rather than a standard one-size-fits-all model.
Under California’s stringent Title 24 Building Energy Efficiency Standards (Part 6), fenestration units installed in San Francisco (Climate Zone 3) must meet strict mandatory limits on Maximum U-Factor (typically ≤ 0.28) and Solar Heat Gain Coefficient (typically ≤ 0.23 for residential and commercial envelopes). Fulfilling these performance benchmarks requires a dual-stage approach: pairing exterior dynamic solar shading systems (such as high-tension motorized exterior zip screens or bioclimatic louvers) with high-performance aluminum frames utilizing polyamide thermal break insulation and low-emissivity double or triple glazing.
| System Specification Category | Standard Commercial Grade | Tejjsons SF Spec High-Performance | Bay Area Architectural Benefit |
|---|---|---|---|
| Aluminium Alloy & Temper | 6063-T5 Standard Recycled | 6063-T6 Primary Architectural Grade | Enhanced structural deflection strength against Pacific coastal wind gusts. |
| Surface Protection Finish | Standard 40µm Powder Coating | AAMA 2605 Fluoropolymer / 25µm Anodized | Complete protection against marine salt air and UV degradation along Ocean Beach & Bayfront. |
| Solar Heat Gain (SHGC) | 0.38 – 0.45 Range | 0.18 – 0.22 (Combined with Zip Screen) | Surpasses Title 24 efficiency; cuts summer air-conditioning load by up to 45%. |
| Acoustic Isolation Rating | STC 28 – 32 dB | STC 40 – 45 dB (Dual/Triple Laminate) | Blocks urban street noise, Muni transit lines, and freeway sound in dense SF corridors. |
| Thermal Break Insulation | 14mm Basic PVC Strip | 24mm – 34mm Polyamide (PA66GF25) | Prevents thermal bridging, moisture condensation, and interior heat loss during cold fog nights. |
Fenestration installed within 5 miles of the San Francisco coastline or San Francisco Bay faces intense atmospheric salinity, continuous humidity, and high ultraviolet exposure. Unprotected aluminum profiles suffer from filiform corrosion and premature coating chalking. Our export-grade solar screen and window frames undergo a multi-stage pre-treatment chemical bath followed by AAMA 2605-compliant PVDF fluoropolymer coating or 25-micron anodic oxidation. This architectural finish guarantees color stability and corrosion resistance under 3,000 hours of continuous salt spray testing (ASTM B117 standards).
While heavily tinted glass reduces solar heat gain, it permanently restricts natural visible light transmission (VLT), forcing reliance on artificial lighting even during overcast foggy mornings. Dynamic exterior sun screens—such as motorized exterior zip screens with woven fiberglass-PVC screen mesh—provide on-demand solar radiation blockage up to 95% during afternoon peak solar sun angles while retaining transparent interior sightlines and 100% natural VLT on foggy days.

Our architectural window and motorized screen solutions are engineered specifically to exceed Title 24 (Part 6) requirements for Climate Zone 3 (San Francisco). By combining high-density polyamide (PA66GF25) thermal break profile chambers with double or triple-glazed Low-E coating technology and optional motorized zip shading screens, our systems achieve Solar Heat Gain Coefficients (SHGC) as low as 0.18 and U-factors below 0.24. We supply complete NFRC-style energy simulation reports for your local San Francisco Department of Building Inspection (DBI) permit filing.
Standard architectural powder coating degrades quickly when exposed to Ocean Beach or San Francisco Bay salt fog. We utilize heavy-duty 6063-T6 architectural aluminum treated with an anti-corrosion chrome-free pre-treatment layer, followed by premium AAMA 2605 fluoropolymer (PVDF) coating or 25-micron anodic oxidation. This formulation is certified to withstand continuous salt spray, high humidity, and intense UV degradation without blistering, peeling, or fading.
Yes. We specialize in custom precision CNC bending and fabrication. We produce architectural radius arches, gothic curves, and custom exterior decorative grilles that match historic San Francisco facade requirements while incorporating modern dual-seal thermal breaks, soundproofing, and hidden integrated solar screens inside the frame cavity.
For dense urban corridors such as Van Ness Avenue, Geary Boulevard, or the Mission District, our soundproof casement and magnetic levitation sliding series achieve sound transmission class ratings up to STC 42 - 45 dB. This performance is realized through asymmetric laminated glass build-ups (e.g., 6mm + 1.52pvb + 6mm), sound-dampening acoustic interlayers, multi-point compression locking hardware, and continuous EPDM perimeter gaskets.
Manufacturing and custom factory fabrication take 4 to 6 weeks following CAD shop drawing approval. Direct ocean shipping from our factory to the Port of Oakland or Port of San Francisco typically takes 18 to 24 days. All shipments are packed in heavy-duty export A-frame crates with corner guards, moisture barriers, and detailed piece-marked packing lists for seamless site delivery and customs clearance.
Our motorized zip screen systems feature stainless steel side-retention tracks and weighted hem bars that lock the screen fabric continuously along the entire vertical guide. Certified to withstand wind gusts up to 60 mph (90 km/h), they prevent fabric blow-out during high wind events in elevated neighborhood locations such as Twin Peaks or Telegraph Hill.
