White aluminium roof lantern interior view

More sky, less roof

Made possible with slimline technology, our aluminium roof lanterns utilise a minimal design. This, however, does not mean that your extension will ever be at risk of draughts or cold spots. Comprised of energy efficient glazing and rafters, each lantern delivers impressively low U-values of just 1.5 W/m²K – that’s twice as thermally efficient as the nearest competitor. This in turn keeps energy bills under control. The space will remain comfortable all year round and the risk of condensation is reduced with these high performance glass roofs.
