Typical on-site timeline 3-10 days with a 4-6 person crew, Prefab ratio ≈ 50%. Zero on-site welding; clean retrofit for rooftops and atriums.

Design follows local codes (EU: EN 1991; US: ASCE 7; AU: AS/NZS 1170). Typical urban wind and snow zones are covered. Typhoon/high-snow regions may require heavier sections, denser purlins, or zoned control strategies [subject to review].

We adopt an integrated strategy of passive drainage plus multi-stage sealing to achieve no leakage under typical heavy rain, with redundancy and care guidance for extreme events.

Exterior, natural drainage: Runoff is managed by roof pitch, drip edges, and node-guided flow; there are no internal drainage channels.

Minimum roof pitch: ≥2% (≈1:50).

Façade/side: EPDM labyrinth sealing with five-path drainage for enhanced redundancy.

Overlapping sashes & sliding ends: Labyrinth sealing with dual seals at sliding joints/ends, effectively resisting water ingress, sand/dust, and wind-driven rain.

Openable system: Interlocking male–female profiles forming a five-layer waterproof architecture, maintaining continuous sealing in both open/close cycles.

Performance note: No leakage in typical heavy rain; for wind-driven rain or extreme storms, verify pitch, eave details, and overlaps per local codes, and provide external discharge paths and overflow provisions (site-specific).

Maintenance: Periodically inspect and clean EPDM gaskets, overlaps, and drainage paths; replace or re-seat as needed to keep the five-path drainage clear.

It can interlock with fire alarm systems (auto open/close per local strategy) and integrates to BMS via BACnet/Modbus. Final logic follows AHJ/fire engineer requirements.

Benefits  

•Open‑sky ambience on clear days; keep trading in rain (natural drainage).

•Lighting presets and low‑noise operation improve ambience & reviews.

•Prefabricated modules: 3–10 days typical on site.

Recommended Models

•One‑way — wall‑attached single‑slope/arched; opening target ~70–75%.

•Bi‑parting — center opening symmetry; opening target ~75–80%.

•Glazing: laminated double‑tempered glass or solid PC (PVDF finish).
