Built with extra-slimline 57mm-wide sections, the range of roof lanterns from Korniche guarantees maximum ambient light with reliable, long-lasting construction. This version of the bestselling roof lantern features black on white frames for a contemporary effect, and cool blue glass, which allows a light transmission of 47%, a U-value of 1.2 W/m2K and solar heat reflection of 60%, providing you with pleasant natural lighting in your living space as well as optimum thermal efficiency. Each Korniche roof lantern is manufactured from lightweight aluminium, and features specially designed insulating T-bars that bridge the gaps between the profiles and finishing caps to provide the greatest possible thermal break, without interrupting the timber-style aesthetics of the overall design. Each unit's lightweight construction belies its strength, with the 6m by 4m unit comfortably withstanding more than eight tonnes. Self cleaning and super simple to install, Korniche roof lanterns can be fitted by roofing contractors, removing the need for external glazing specialists and therefore cutting down your project's time and costs significantly. With all this plus innovative, tamper-proof safety features as standard and premium seals and gaskets for reliable weatherproofing, the range from Korniche has gained a solid reputation for peace of mind that keeps the heat in and the weather firmly out.
