A revolution in rooflight design

The stunning new Lumen Planus Accoya ™ flat roof skylight range constructed entirely from Accoya® timber - a leading high technology long-life wood, renowned for its durability, stability and a truly sustainable material of the 21st century.
Available in a range of standard and bespoke sizes, this range of beautifully crafted rooflights are triple glazed and offer exceptional thermal performance with a whole frame U-Value of just 1.1Wm2K.

Outstanding quality as standard

As with all Lumen rooflights, the Lumen Planus Accoya ™ range is manufactured and hand finished by our craftsmen here in the UK to the highest quality standards.

This exceptional rooflight, with its lighter framing structure, incorporates triple glazed neutral solar control, self-clean glazing, with 90% argon gas filled cavities as standard.

Designed to match your requirements

Available in fixed frame or opening, smaller casements can be manually operated with our UK manufactured screwjack mechanisms in brass or chrome. For sizes larger it is necessary to have opening casements electrically operated and this can be achieved with a variety of options including remote control, switch operated and rain and temperature sensors.

The Lumen Planus Accoya ™ range of flat skylights also benefits from a wide range of colours including, RAL and Farrow & Ball and even a colour match service to your personal requirements.

It is also possible for customers to specify differing internal and external colours rather than just a single option.
