The external walls of Climatic modular buildings are ready for all types of facade systems available on the market. Ventilated facades are installed in a way that eliminates thermal bridges occurring on fasteners. A standard modular building is equipped with a thermal-insulated flat roof with a parapet wall. Its structure can be reinforced at the design stage, making it possible to create green roof layers. Partition walls are installed using framed partition systems compliant with the highest standards of fire-proofing, moisture resistance and impact resistance, and allows easy rearrangement during building operation.
