Lightweight Exterior Wall Systems (LSF)

In recent years, the use of Lightweight Steel Framing (LSF) (also referred to Light Gauge Steel (LGS)) as a structural and non-structural construction element has emerged and proliferated. This construction method has replaced the traditional method of using brick and mortar.

LSF Systems allow for detailed planning of all the construction phases and the use of higher quality construction materials.

With this system, Terraco’s goal is to provide effective building solutions by offering better performance than traditional systems without increasing cost and time, and affecting sustainability. The use of Terraco Exterior Insulation Finishing Systems (EIFS) as part of LSF / LGS achieves this objective.

Light Steel Framing

LSF Systems incorporating an EIFS System have the potential to achieve:

  • Lower energy consumption due to continuous wall insulation results in carbon dioxide (CO2) reduction 
  • Reduction of a building's external wall weight
  • Reduction of the construction timescale
  • Reduced construction cost
  • Reduced long-term heating / air conditioning cost

The attached LSF Finishing Systems brochure contains technical details with regards to:
