Thermalight Roof Lanterns

Are style and maximised sky views the priority? Look no further than Thermalight. Thermalight is the ideal solution where clean and classy lines, outstanding light transmission and blue-sky views are required.

The fixed unit is designed with no visible framework to maximise daylight, while the low-profile units use triple-sealed, structurally bonded glass for improved heat insulation and energy efficiency. While Thermalight units are double-glazed as standard, triple-glazed units are also available.

Thermalight Roof Lanterns

Thermalight roof lanterns have a contemporary and unique design that utilises the latest state-of-the-art technology in structural silicone glazing, creating a totally frameless product with one of the slimmest sightlines on the market. This exclusive design has been adopted across our Pyramid and Octagonal rooflight ranges.

The ultra-slim glass-to-glass joints creates a stunning flat roof lantern feature, available with a 40° pitch and 20° & 30° options also available, guaranteeing that a generous amount of natural light floods into the room beneath.

The Fixed Thermalight unit is specifically designed with no visible framework to ensure that the maximum amount of daylight floods into the space. The use of flush glazing external metalwork also means that the unit does not suffer from the ‘water-pooling’ effect experienced by some other products.
