The Lumen Planus is designed for use on a flat or low pitch roof construction including lead, zinc sheet, copper and asphaltic material. The rooflight benefits from the fine lines of steel ensuring maximum daylight with the minimum amount of framework.
Our rooflights for flat roof applications are manufactured from a CR4 mild steel with a PZ790 powder coat as standard or can be upgraded to a grade 316 stainless steel to ensure maximum protection against the elements and standing water. The frames are painted to RAL9005 black.
The range can be manufactured using the Conservation design or utilise many of the benefits of the Evo range. The stock sizes are supplied with a high specification of Pilkington glazing, unique locking system, trickle ventilation and American Ash interior liner.
Smaller casements are supplied manually opening. For sizes larger than 1200mm x 1200mm it is necessary to have opening casements electrically operated.
Bespoke sizes and designs available, please talk to our team concerning your requirements.
Please note that we are not able to accept returns of products that have been adapted to customer requirements. In addition we cannot refund delivery charges, bespoke and fixed rooflights, electric actuators and flashing kits. We apply a 40% restocking charge to all other items so please ensure that you chose the right size to avoid further costs.

Lumen Rooflight Maintenance
Industrial coatings are no different to the paint on your car - they need cleaning and maintaining
The powder coat to the roof light protects the metal underneath.
If you are unable to adhere to the maintenance guidelines we recommend that you speak to us about using stainless steel.

Our brief was to manufacture a rooflight for a new flat roof extension which would be the kitchen area of a property in Berkshire. The installing contractors supplied a drawing of their required design and our team came up with the solution. At over 8 metres in length and 1.2 metres high, the rooflight had to comprise of both opening and fixed casements. The design was then altered when the client requested that roof light had just 4 casements sections, 2 of which needed to open. To ensure the casements could open we chose to use KA66 twin chain drive electric actuators with a 350mm stroke length.
This rooflight was supplied as the smallest of a pair of opening flat rooflights. Both were supplied to a residential project in Gloucestershire. The client wanted to maximise the amount of natural daylight into the property and to have them both opening for ventilation. At 1500mm x 1500mm, the second rooflight was the largest that we have supplied with manually operated winders. The drawing here shows the location of the casement and how the flat rooflight is fixed to the up stand section.
The client originally enquired about our Lumen conservation rooflight but then switched to the flat rooflight design due to the shallow pitch. In addition the rooflight was to be fixed shut with the inclusion of a trickle vent. As with our conservation skylight, the top section forms part of the overall frame to give the appearance of a casement. By having a continuous piece there is no opportunity for water to penetrate the casement.
All of these bespoke projects were produced with the following specification:
3mm stainless steel frame and casement (where required)
Wet spray textured paint finish to RAL9005 matt black
American oak interior liners
24mm double glazed units comprised of toughened Pilkington Activ self clean, argon gas and toughened Pilkington Optitherm.
