The Invisio Floorlight System is a walk-on glass floorlight designed to bring natural light through roofs, floors and lower-ground spaces while maintaining a clean frameless appearance. Its thermally broken hidden fixing detail helps reduce cold bridging, supporting improved insulation and better long-term comfort.

Engineered for pedestrian traffic, the system is suitable for roof terraces, basement lightwells, internal glass floors, external walk-on rooflights and high-end architectural glazing projects where daylight needs to pass safely between levels.

Sieger Systems supplies and installs thermally broken glass floorlights across London, Buckinghamshire, Berkshire, Oxfordshire, Hertfordshire, Surrey, Bath, Bristol and Somerset.
