Introducing the sleek Flat Roof Skylight 400 x 1500 mm from the esteemed Regal Glass Group, a masterpiece in the realm of skylight windows. This elongated skylight is designed to redefine flat roof spaces by maximizing natural light entry, ensuring your interiors are bathed in the rejuvenating glow of daylight.

Crafted with the latest triple-glazed technology, this skylight achieves superior thermal efficiency with an impressive U-value of 0.9 W/m²K. At its core, a 15-millimeter warm Edge spacer filled with Argon gas between each pane of glass significantly limits heat transfer, maintaining a consistent and comfortable indoor atmosphere year-round.

The true beauty of this skylight lies in its frameless design, which not only offers a sleek, contemporary look but also allows for unobstructed natural light to flood the space below. This minimalistic approach ensures that every ray of light is captured and utilized, brightening your interiors more effectively than ever before. Equipped with a self-cleaning mechanism, activated by sunlight, these skylights maintain their clarity and transparency with minimal maintenance, providing you with a clear view of the sky above without regular cleaning hassles.

This model is versatile, suitable for installation at pitches ranging from 6 degrees up to 45 degrees, allowing it to adapt to various architectural styles and requirements. Alongside enhancing the visual appeal of your space, it also offers sound reduction, UV protection, and is built with safety toughened glass to ensure durability and security.

Adhering to British Standards & Building Regulations, the Flat Roof Skylight 400 x 1500 mm is fully compliant, featuring all necessary Safety Markings and the CE mark, denoting its conformity with the highest EU quality and safety standards.

At Regal Glass Group, we understand the importance of choice and customization.
