Our frameless roof lanterns are particularly popular among architects and designers for rooms that need an injection of natural light. Simply by installing a roof lantern into a room, you can completely transform the look of an interior with the illusion of more space and a luxe feel. Roof lanterns can enhance and revitalise a room, giving it a feature and focal point.
The InfiniLIGHT® is the epitome of luxury with a lightweight and slimline frame, self-cleaning glass for minimal upkeep and created using premium grade materials. Adding a roof light adds a whole range of features and benefits to the property or building they are installed into, with high performance functionality and aesthetically pleasing finish.
Our unique roof lights offer excellent benefits all year round, keeping a property warm with exceptional insulation levels during the colder months and reflecting the suns glare in warmer months. Intelligently designed with clever functionality, they are a sophisticated addition featuring superb design.
Unlike traditional windows, the InfiniLIGHT® is installed horizontally on the roof which is why they are often popular in modern extensions such as orangeries and conservatories. They feature advanced and bespoke technology, tailored to suit a range of architectural types whether traditional or contemporary.
