Ultra-low energy consumption aluminum alloy Grade B fireproof window (outward-opening and top-hung, with built-in blinds)

A key advantage is the synergy of reliable Class B fire safety and ultra-low energy consumption. Fire performance meets Grade B requirements: steel-reinforced frames, expanding seals, and fire glass block flame/smoke for 1h, ensuring occupant evacuation. Ultra-low energy features outperform conventional fire windows: double thermal breaks + quadruple-pane krypton glazing cut heating/cooling costs by 50–60% annually, meeting global ultra-low energy standards (e.g., Passivhaus). The double Low-E coatings reflect 90% of infrared radiation—retaining indoor heat in winter and blocking solar heat in summer—while maintaining 85% visible light transmission (no need for extra artificial lighting). Unlike energy-inefficient steel fire windows, aluminum frames are lightweight (reducing building load) and corrosion-resistant (suitable for diverse climates), with anti-peeling powder-coated finishes (resisting temperature fluctuations). Airtight design also enhances sound insulation (40+ dB), reduci…
