KingsView™ 1000x3000mm (Internal Size) Extra Large Panoramic Rooflight

Flood your extension with natural light using our flagship 1m x 3m frameless skylight. Specifically engineered for wide-span UK residential projects, this architectural unit fits a 1000x3000mm internal structural opening, providing an uninterrupted “infinity glass” view with maximum structural safety.

Why the KingsView™ 3-Metre Series Excels:

  • Anti-Sag Technology: Spanning 3 metres requires elite engineering. 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 finish.
  • Maximum Thermal Performance: Achieve a 0.9 W/m²K U-Value. This triple-glazed unit is fully Building Regulations compliant (Part L), keeping your open-plan space warm in winter and cool 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 Security: Fully UKCA Certified and rated as non-fragile, backed by an industry-leading 20-Year Warranty.

Critical Specifications:

Internal Size 1000 x 3000 mm (Structural Opening)
Glass Build 8mm Toughened Top Pane (Triple Glazed)
Performance 0.9 U-Value | 39dB Sound Insulation
Unit Weight Approx. 181.8kg
Installation Min. 8°–10° Pitch Recommended for Run-off

— Delivery & Pitch Note:

Due to the 3m span, a minimum pitch of 8°–10° is required to ensure efficient water run-off. Delivery is Kerbside Only (181kg); appropriate manpower or lifting equipment must be available on-site.

The ultimate wide-span daylight solution for luxury builds. Direct-from-manufacturer pricing with full technical support for architects and trades.

CE & ISO CERTIFIED
Precision Fit: 10-year leak-proof warranty included.
Transit-Safe: Arrived damaged? We swap it in 24h.

      TECHNICAL GUIDE

      Step-by-Step Installation

      Ensure your project meets British Building Regulations with our verified fitting process

      01

      Structural Prep

      The upstand opening must allow for a 5mm tolerance on each side. The internal distance must be 10mm larger than the quoted size.

      02

      Support Timber

      Install 25x50mm timber support. Ensure the top of the support for triple glazed units is exactly 42mm below the upstand top.

      03

      Seal & Level

      Apply foam rope on the timber support to level discrepancies and prevent glass cracking. Failure to use foam rope voids your warranty.

      Pro Tip: Use DOWSIL 791 Weatherproofing Sealant. DO NOT use acrylic sealants as they cause loss of adhesion and leaks.

      Original price was: £ 1.260.13.Current price is: £ 1.079.02. incl. VAT

      KingsView™ 1000x3000mm (Internal Size) Extra Large Panoramic Rooflight

      Flood your extension with natural light using our flagship 1m x 3m frameless skylight. Specifically engineered for wide-span UK residential projects, this architectural unit fits a 1000x3000mm internal structural opening, providing an uninterrupted "infinity glass" view with maximum structural safety.

      Why the KingsView™ 3-Metre Series Excels:

      • Anti-Sag Technology: Spanning 3 metres requires elite engineering. 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 finish.
      • Maximum Thermal Performance: Achieve a 0.9 W/m²K U-Value. This triple-glazed unit is fully Building Regulations compliant (Part L), keeping your open-plan space warm in winter and cool 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 Security: Fully UKCA Certified and rated as non-fragile, backed by an industry-leading 20-Year Warranty.

      Critical Specifications:

      Internal Size 1000 x 3000 mm (Structural Opening)
      Glass Build 8mm Toughened Top Pane (Triple Glazed)
      Performance 0.9 U-Value | 39dB Sound Insulation
      Unit Weight Approx. 181.8kg

      — Delivery & Pitch Note:

      Due to the 3m span, a minimum pitch of 8°–10° is required to ensure efficient water run-off. Delivery is Kerbside Only (181kg); appropriate manpower or lifting equipment must be available on-site.

      The ultimate wide-span daylight solution for luxury builds. Direct-from-manufacturer pricing with full technical support for architects and trades.
