The main difference between a skylight and a roof lantern is that a roof lantern is a pitched structure which sits upon a flat roof, as opposed to a skylight which is flat and fitted into the construction of a roof.

Timber – We use a premium grade knot-free laminated Redwood timber, selected for its durability and stability. Our timber is sourced from fast-growing, FSC® certified forests and is a sustainable alternative to both tropical hardwoods and PVC.

Aluminium – Our lanterns are fully capped in marine-grade, powder-coated aluminium.

Glass – Pure in colour with no tint, our standard glass makeup is high insulating 4-16-4mm toughened glass units with Soft Low-E coating, argon gas-filled cavity and warm edge spacer bar.

We also offer upgrade options to our Security, Solar Control and Low Maintenance glazing options.

In our products, these thermal breaks include resin, silicone and styrofoam, which separate the conductive aluminium components to provide superb thermal insulation.
