At Advanced Glazing Systems, we offer both Korniche and Atlas roof lanterns across Essex & London, each expertly crafted from durable aluminium. Aluminium is the perfect material for roof lanterns due to its strength, slimmer frames, and exceptional thermal performance. Our lanterns achieve impressive U-values from 1.0, with triple glazing options, solar control glass to reflect the sun’s energy, and self-cleaning glass. We offer a range of colours, including Anthracite Grey and White, with bespoke colours available to match your style.
Here are some great reasons to add roof lanterns to your home for natural light and elegant style.
Our roof lanterns are designed with thermal breaks and energy-efficient glazing to help reduce heat loss and lower your energy bills. The use of low U-values ensures that your home stays comfortable throughout the year.

Great service from Start to finish.
After looking around for a while I made the great decision and chose AGS.
From the start Tyler was very professional and helpful on the phone, he sent me pictures by email of doors in the colours I was thinking about and also pictures of the fixtures and fittings so I could compare colours.
Tyler was very communicative throughout the whole process. On the day of installation the fitter was punctual and polite and clearly knew his stuff, door is working a dream. Especially happy with the making good and how he installed the trim, such a clean and tidy finish.
