Heritage Rooflights

The Lumen Heritage rooflight retains the low profile steel framed design, the Pilkington Activ self-clean double glazing and is still hand-crafted from our purpose built facilities in Devon, using the highest quality components and skilled workmanship. The main differences between our Heritage version and our original Conservation rooflight is that the Lumen Heritage rooflight offers twin American ash liners on both the casement and the outer frame and the Lumen Heritage range is internally glazed, which further boosts the security performance of the rooflight.

One of the drawbacks of the original Conservation rooflight design was that under certain conditions the exposed internal steel parts of the rooflight were susceptible to condensation. The Lumen Heritage range incorporates a hand crafted American ash lining in the casement as well as a sculpted timber glazing bar which removes the potential for condensation to form on parts that were originally steel. The Lumen Heritage rooflight has a centre pane u-value of 1.0 W/m2K and a whole frame u-value of 1.6 W/m2K.

The Heritage rooflight is available as a fixed casement, manual operation with brass or chrome screwjack mechanism or with a range of electric actuation and accessories. A range of manual and electric blinds are also available.

This premium flush fitting Conservation rooflight is ideal for installation in any project but especially period properties, Listed buildings, barn conversions or areas where flush fitting glazing is required. In addition to the range of stock sizes we can produce sizes and specifications to make your rooflight as unique as your project.
