Flat Roofs

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.
