Lantern roofs & skylights

Sheerline Lantern Roofs

A lantern roof is an exciting and inspiring alternative for glazed roofing

Combining the very best of both worlds, with the light, open feeling of a conservatory and the tall, pillared grandeur of an orangery. Always warm, welcoming and cosy, thanks to advanced insulation technology, innovative securty features and thermally efficient glass.

It gets its distinctive look from its lantern shaped roof, a real focal point for your new room.

Whatever the weather Thermlock® technology helps keep you comfortable and heating bills lower

Exceptional thermal performance (innovative Thermlock® multi-chamber technology) keeps the Lantern well insulated against the UK elements.

High performance 28mm glazing: Iceni Lantern Roofs offer leading thermal performance, superior to traditional systems based around 24mm glazing.

A unique co-extruded perimeter seal also makes sure draughts and moisture are kept on the outside.

28mm glazing allows for acoustic dampening glass to be fitted if required.

With great looks from every angle – due to our unique ultra low line aesthetics

Slim sightlines of 50mm for rafter, hip and ridge enhance the light entering the lantern; creating airy and bright interiors.

Iceni lanterns also feature super low line aesthetics so the rafter and hip top caps sit near to the outer glazing level.

No unsightly angles: Completing this refined architectural appearance, the corner and rafter end -aps run in line with the perimeter of the lantern.
