Ultrasky Lantern Roof

Thermally Broken Inside and Out

With fewer bars than other roof lanterns, the Ultrasky Lantern is perfect for extensions and orangeries with a flat roof, ideal for creating a focal point in a dining room, kitchen or living area

A high performance thermal break in the ridge, an insulating eaves rail and other thermal breaks throughout the roof lantern provide unrivalled thermal performance.

A super strong ridge means Ultrasky requires less bars than other lanterns and can span up to 4m x 5.85m

Available in uPVC or Aluminium internally or externally with a choice of performance glazing options Ultrasky lantern is available in any RAL colour.

The 25 degree pitch optimises light refraction, drawing more natural light into the room below.

Ultrasky’s unique Stormshield provides triple layers of protection against extreme weather at the ridge ends.

Installed in minutes – Ultrasky is easy to glaze and extremely fast to install with no drilling or cutting and no fiddly trims.

Key Product Information

Rectangular double ended lanterns, with a width up to 4m and a length up to 5.8m*. 25 degree fixed pitch to all four sides, with a thermally broken aluminium ridge body.

Low profile eaves rail (no gutter) designed to be fitted with oversailing 24mm double glazed units (which can be supplied with the Lantern).

Ultrasky is designed around maximum uninterrupted sight lines – glazing bar numbers are reduced (or can be added if you prefer) and the ridge board and hub ends are as unobtrusive as possible.

The thermal performance has been optimised to make it suitable for extensions in domestic properties. Typical U value with 1.2 glass for a 1m wide x 2m long lantern is 1.4 W/m2K.

How to Measure

A timber kerb of 150mm high x 70mm wide (not supplied) must be fitted around the opening in the flat roof – the weatherproofing membrane laps onto the top face of the kerb.

IMPORTANT: SET OUT DIMENSIONS ARE ALWAYS MEASURED TO EXTERNAL FACE OF KERB.
