In 2024/2025, Sament Group supplied and installed 264 daylighting solar tubes from the Architectural Line, as well as dynamic smoke curtains from the Industrial Line, at the production facility of BTL Industries EAD in Plovdiv.

Solar tubes, which provide natural light through the roof or facade, are a reliable way to ensure an ergonomic and comfortable environment in workspaces when this cannot be achieved by other means.

In the production facility of BTL Industries EAD, light tubes are the only product providing natural light through the roof. The configuration and placement of the tubes ensure good natural daylighting and a comfortable working environment inside the building.

This element of the building systems was carefully selected for its excellent thermal insulation properties and is in harmony with the other components of the building, which is designed for a high level of energy efficiency and comfort. The building was named "Building of the Year 2025" in the "High-Tech Manufacturing Buildings" category.
