The Stratus lantern was designed around thermal performance first: a TUV-certified aluminium system whose chambered profiles and warm-edge glazing keep heat in the room rather than leaking through the roof.

We supply and install Stratus roof lanterns across the UK in two, three and multi-pane configurations, with the full glass and colour range.
Stratus uses a structurally bonded, thermally broken aluminium frame with concealed fixings and a clean square-cut internal pelmet line that suits both contemporary and traditional rooms. U-values reach 1.0 W/m²K with the upgraded glass package, and the system carries independent TUV certification for its thermal claims — rare in this market. Configurations run from compact two-bar designs to large multi-hip roofs, all made to measure. Stocked colours are anthracite, black and white with the full RAL chart to order.
