Lightway is the ideal product to bring daylight into attics, hallways and closets that are located below roofs in Passive Houses. Made with CO2 blown XPS (low Global warming potential).

Combining this integrated, fully over-insulated double pane glass Blue Performance 300 insulation break with the Lightway pitched roof or flatroof 300 series (purchased separately) eliminates the performance issues associated with conventional Solar Tubes – thermal bridges, heat loss, condensation, and air tightness – and creates the ideal product for bringing daylight into Passive Houses and high performance buildings.
