Why choose a Stratus Roof

The purpose designed Stratus aluminium lantern roof system is discreet yet stylish. Stratus allows light to flood into your home’s interior, the ideal modern lantern solution, coupling sleek contemporary looks with truly outstanding performance.

Create light, airy spaces

Designed from the ground up around an innovative thermally broken system, it provides excellent thermal performance – keeping cool in the summer and warm in the winter – while delivering the architectual refinement you’d expect of a high end aluminium lantern system.

Whether you are building a new kitchen-diner extension or replacing an existing lantern roof, Stratus will help redefine your home, creating light and airy spaces for you to enjoy.

Simply built better

Every element of the Stratus Thermal Lantern Roof has been designed to be exceptional. From the low profile 20˚ pitch that allows us to use purpose designed cappings that keep sight lines to a minimum – and your view of the sky maximised – to the discreet black
finish of our perimeter beam, that ensures if you view the lantern from above all you’ll see is glass and a discreet shadow line.

Stratus is high-quality British engineering at its best.

Innovative Technology

Thermal break technology ensures that Stratus is warm in the winter and cool in the summer. Every element of the lantern has an ultra-low conductive element that separates the inner and outer aluminium skin, helping keep heat transfer down, and your heating bills low.
