Lead glass does not exist in isolation. It must integrate seamlessly with lead‑lined doors, modular shielding panels, and wall framing.
| Integration Feature | Jovvi Specification | Benefit |
|---|---|---|
| Matching lead equivalence | Glass Pb eq. matches adjacent wall within ±0.1 mm | No weak spots around window perimeter |
| Frame interoperability | Compatible with ETS‑Lindgren, Nelco, Ward-Bray frames | Retrofit without reframing |
| Thermal expansion matching | Coefficient (9×10⁻⁶ /°C) matches aluminum frames | No gap opening over temperature swings |
| Seal compatibility | Neoprene gasket (Shore A 45) – industry standard | Off‑the‑shelf seal replacement |
| Lead tape overlap | Factory‑cut lead tape strips (50 mm wide, 2 mm thick) | Simple field installation |
Jovvi provides frame compatibility drawings for 15 major lead‑lined wall systems worldwide.
Scenario A: New Construction with Modular Lead Panels
Challenge: Panels arrive pre‑cut with window opening. Glass must fit exactly (±1 mm).
Jovvi solution: Jovvi delays glass cutting until modular panel shop drawing is final. No field trimming.
Result: Zero installation delays.
Scenario B: Retrofitting into Existing Lead-Lined Door
Challenge: Door has small viewing window (often degraded acrylic). Door cannot be replaced.
Jovvi solution: Custom‑cut 1.5–2.0 mm Pb glass to fit existing door frame. Weight limit: door hinges can handle ≤20 kg.
Result: Door upgraded from acrylic (yellowed) to glass (clear, durable) without new door.
Scenario C: Corridor Viewing Between Two Lead-Lined Rooms
Challenge: One glass panel must shield two rooms from each other (e.g., CT and MRI). Both sides need clarity.
Jovvi solution: Double‑sided AR coating. Symmetric construction (no orientation arrow – both sides identical).
Result: Clear view from either side; no installation mistakes.
Jovvi provides system‑level documentation:
Compatibility matrix – lists which Jovvi glass models work with which wall systems
Torque specifications for each frame type (varies by manufacturer)
Lead tape application guide for corner sealing (diagrams for butt, lap, and miter joints)
Thermal gap calculator – minimum gap required for given temperature range
Warranty note: Jovvi warranty covers glass. Wall system warranty remains with wall manufacturer. Jovvi provides technical support for integration but does not assume liability for wall system failure
