A Better Lantern 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.
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 architectural 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.
Colour and Design Options
Available in 2-way, 3-way or contemporary designs, with sizes up to 3m x 6m, this high end, high-performance lantern roof is ideal for modern living. Stratus is ideal for fresh, bright interiors that want to be opened up and bathed in light.
Stratus comes in a choice of two hard-wearing exterior powder coated finishes, with the option of a white or grey interior finish. For the ultimate in minimalism, the innovative contemporary style supports the ridge solely by the hip rafters, for an ultra-slim, clean and modern look.

Innovative Fully Thermally Broken Lantern Roof
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.
Polyamide nylon, glass composite thermal breaks are 533 times more thermally efficient than aluminium!
More thermally efficient than conventional aluminium roof systems.
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 sightlines 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.
