KingsView™ 1500x3000mm (Internal Size) Extra Large Architectural Rooflight
Transform your extension with our flagship 1.5m x 3m frameless skylight. Engineered specifically for grand-scale UK builds, this architectural unit fits a 1500x3000mm internal structural opening, providing a massive “infinity glass” aesthetic without the structural compromises found in standard-spec glazing.
Why the KingsView™ 3-Metre Flagship Leads the Market:

- Acoustic & Solar Protection: Blocks up to 39dB of external noise and features Sunlight-Activated Self-Cleaning technology—essential for maintaining large, hard-to-reach roof spans.
- Certified Strength: Rated to support high snow/wind loads, fully UKCA Certified, and backed by an industry-leading 20-Year Warranty.

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