All Lumen rooflights are manufactured entirely in Great Britain. It is not only this, but our attention to detail and use of quality materials that sets Lumen apart from the rest.

Whether a stock size or bespoke our aim is to provide you with the best rooflights on the market. We combine leading design with the finest craftsmanship to offer rooflights that are as unique as your project.

Every Lumen rooflight is hand finished at our factory in Devon and is supplied with Pilkington Activ self-clean solar control double glazed units, American ash interior linings and British manufactured winding mechanisms.

Not just good on the inside, our Lumen Heritage range is ideal for installation in any project but especially period properties, Listed buildings, barn conversions or areas where flush fitting glazing is required. The low profile design remains unobtrusive and maximises light and ventilation into the space below.

The reality is: yes our rooflights are likely to be more expensive than others. But it’s a beautiful rooflight, not mass produced or constrained by material costs, and the interior is far more detailed and exceptional than most other rooflight manufacturers.

In a world where price is regularly put ahead of quality; we’d like to think that Lumen is the rooflight your building would choose.
