Things You Need To Know About Pre-Engineered Building Insulation

Pre-engineered buildings (PEB) have set a benchmark in the history of structural engineering. These pre-engineered buildings are built cohesively with suitable building materials such as rigid-steel frames, cold-formed structural components and related structural panels for external or internal purposes. PEB steel structures are built offsite in a very controlled environment and shipped to the building site for further purposes.

Hence, these structures are perfect solutions for industrial facilities, restaurants, warehouses, medical offices, and related erected structures. However, it would be best to take necessary protection measures for a PEB or any metal building as various internal and other environmental conditions can destroy it. Hence, you need perfect insulation to keep your structure’s environment at the right temperature despite the changing ecological conditions.

In this post, let us see the importance of PEB insulation and the primary kinds used for this purpose.

Importance Of Insulation PEB:

Insulation is a thin lining or covering material applied on the outer surface of the steel structural building to protect, prevent, and reduce leakages, heat transfers and structural passages. Despite your environment, if your steel structure encloses human occupancy, you must insulate the building because,

  • It retains the heat and cold environment of the structure, thereby making them suitable for the ecological condition.
  • It reduces energy costs considerably.
  • Moisture condensation is prevented when insulation is applied to the building. Condensation can weaken the durability of the building.
  • It also acts as an acoustic barrier and prevents sound transmission considerably. These insulators have audio absorption quality, which absorbs the extreme sound level and reduces the transmission of the internal vibration.
  • It reduces the ROI of the business. Insulation acts as a barrier between the steel, thereby preventing rusting, which occurs due to the reaction of humidity. 

Facade Or Facing:

The facade acts as an add-on value to the steel building to enhance the insulation performance. This facade protects the insulation and acts as a vapour retarder. It also allows the insulator to hold onto the building cohesively for longer. However, PEB structure manufacturers use facades for air and vapour barriers in their buildings.

Facades protect the building from moisture condensation, fire norms, and many more. Most of the facades include solutions like polyethene, vinyl, polypropylene, metalised polyester, and aluminium foil.

Primary Insulation Types:

Four types of primary insulation are used for PEB buildings. 

Glass Wool: 

It is an insulator made of glass fibers which are arranged in a wool texture using a binder.

Mineral Wool:

In mineral wool, slag, ceramics, or rock minerals are fibrous materials formed by spinning or other methods.

Spray Foam:

It is formed from the chemical substance polyol resin and isocyanate, which react with one another to form a duct. It expands to 30-60 times its original volume and extrudes in the concerned place.


These are boards made of inorganic and organic materials that are cohesively bonded with facers or facades on either side. It is used on roofs, ceilings, and walls of commercial and industrial buildings.

Hence, complementing the structure with shielding is essential in the long run. We at Metfraa have experienced experts who can help you with all your building requirements. Approach us now for expert guidance!
