Wendland uPVC Roof Lantern

Wendland Aluminium Roof Lantern

The Wendland Aluminium Roof Lantern delivers a perfect balance of sleek design, thermal performance, and ease of installation. Designed to flood your space with natural light, its 20° pitch maximises brightness while creating a striking architectural feature for any flat roof extension, kitchen, or orangery.

Engineered with a strong ridge system, the Wendland lantern uses fewer rafters than traditional designs, resulting in cleaner sightlines and a more open feel. With no visible fixings and a range of clip-on components, the overall finish is neat, modern, and built for long-term performance.

Thermal efficiency is at the core of the system, with features such as thermally sleeved rafters, insulating polymer barriers, and high-performance gaskets working together to reduce heat loss and condensation.

Simple to install and made to measure, this lantern is ideal for both homeowners and trade professionals looking for a reliable, high-quality solution that performs as well as it looks.
