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)

Performance 0.9 U-Value | 39dB Sound Insulation
Unit Weight Approx. 181.8kg

TECHNICAL GUIDE

Step-by-Step Installation

Ensure your project meets British Building Regulations with our verified fitting process[cite: 1, 4].

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[cite: 40].

02

Support Timber

Install 25x50mm timber support[cite: 49]. 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[cite: 69]. Failure to use foam rope voids your warranty[cite: 70, 83].

Pro Tip: Use DOWSIL 791 Weatherproofing Sealant[cite: 103]. DO NOT use acrylic sealants as they cause loss of adhesion and leaks[cite: 104, 82].

Transform your home with our triple-glazed flat roof skylights, maximizing natural light and thermal efficiency. Pair them with our separately sold Insulated Upstand, featuring 40mm core insulation to cut heat loss and lower energy costs.
