KingsView™ 1200x2500mm (Internal Size) Extra Large Elongated Skylight

Flood your home with natural light using our flagship 1.2m x 2.5m frameless rooflight. Specifically engineered for large-scale extensions and modern open-plan living, this architectural unit fits a 1200x2500mm internal structural opening, providing a seamless "glass-to-sky" view while delivering industry-leading thermal insulation.

Why the KingsView™ 2.5-Metre Series Excels:

  • Anti-Sag Engineering: Spanning 2.5 metres requires superior structural tension. We use an upgraded 8mm toughened glass top pane to ensure the unit remains perfectly rigid. This prevents "glass bowing" and ensures Zero Water Pooling for a leakproof, clear finish.
  • Maximum Thermal Performance: Achieve an incredible 0.9 W/m²K U-Value. This triple-glazed unit is fully Building Regulations compliant (Part L), designed to keep your home warm in winter and significantly reduce heat gain in summer.
  • Acoustic & Smart Glass: Blocks up to 39dB of external noise and features Sunlight-Activated Self-Cleaning technology—essential for maintaining large, hard-to-reach spans.
  • Certified Strength: Rated for heavy snow and wind loads, fully UKCA Certified, and backed by an industry-leading 20-Year Warranty.
