The Light Gauge Steel (LGS) framing technology developed by MBG Industry offers all the recognized advantages of timber-frame systems while eliminating their main drawbacks. It is a modern, high-performance, and durable construction solution suited to residential, commercial, and industrial buildings.
Technical & Functional Advantages
LGS systems offer numerous benefits in design, execution, and operation:
– Very high architectural flexibility, allowing extensive design freedom
– Competitive solution with an excellent performance-to-overall-cost ratio
– High mechanical, thermal, and acoustic performance
– Significantly shorter timelines and cleaner construction sites
– No chemical treatment of the structures required
– Reduced wall thickness, freeing up usable interior space
– Optimized foundations thanks to the lightness of the structures
– Strong capacity for extending or modifying existing buildings
– Excellent resistance to seismic activity
– Environmentally friendly solution with a low carbon footprint
Thermal Performance
MBG’s LGS building systems are designed to meet the minimum requirements of current thermal regulations for residential and commercial buildings.
Through the integration of high-performance insulating materials and a design that limits thermal bridging, the wall systems provide a level of thermal insulation that complies with applicable standards, helping reduce energy consumption — as reflected in high-energy-performance building indicators (low-energy housing).
Acoustic Performance
MBG’s solutions achieve the acoustic insulation levels required by regulations, based on surrounding noise levels, using the sound reduction index (Rw) and different wall configurations.
| Category | Surrounding Noise Level | Façade Sound Insulation |
| 1 | +de 81 dB | 45 dB |
| 2 | entre 76 et 81 dB | 42 dB |
| 3 | entre 70 et 76 dB | 38 dB |
| 4 | entre 65 et 70 dB | 35 dB |
| 5 | entre 70 et 65 dB | 30 dB |
These performance levels ensure acoustic comfort suited to urban, industrial, and residential environments.
Finishes & Architectural Appearance
The interior faces of the wall panels are compatible with standard building finishes, thanks to the use of plasterboard or fiber-cement board. This versatility allows for aesthetic and functional integration according to the project’s architectural requirements.
Air & Water Tightness
Air and water tightness of LGS constructions can be fully ensured, provided joint systems, membranes, and cladding are installed with rigorous care. This directly contributes to the building’s durability and improved overall energy performance.
