Thermal Decoupling & Energy Performance (Klimabonus & Passivhaus)
Luxembourg has established some of the European Union's strictest building envelope regulations, mandating near-zero energy consumption under the Règlement grand-ducal sur la performance énergétique des bâtiments. For both residential garages connected to living spaces and commercial storage environments, non-insulated steel shutters are being phased out rapidly.
Our thermally broken aluminum roll-up profiles utilize a multi-chambered 6063-T6 extruded exterior shell filled with ultra-dense, 100% CFC-free polyurethane foam (48 kg/m³). Combined with specialized lintel sealing brushes and EPDM thermal gaskets along the guide rails, our systems achieve complete door U-values as low as 1.4 W/m²K, completely preventing condensation and energy leakage during freezing Ardennes winters.
