In 2022, Sament completed the implementation of a modernization project for the roof day lighting system of Alkomet, Rolling Mill 2 production facility. The natural ventilation system based on GLOS DL BT continues roof lights was delivered and installed by Sament in 2017.

Due to the high level of  heat emissions resulting from the technological processes in the building, a project was launched and implemented to expand the functionality of the roof lighting system with an extension for permanent natural ventilation through aeration devices of the Glos HM type integrated into the sky lights.

The products from the Glos HM series are elements of Sament's Industrial Ventilation line, designed for permanent extraction of  heat emissions from the interior of the building as a result of technological processes, regardless of the weather conditions.
