Materials Used in Prefabricated Modular Buildings – Houses

Prefabricated Buildings – houses (prefab houses) are specialised houses where the components as walls, floor, windows or roof panels are constructed off-site in standard sections to be assembled and finished on-site. As an alternative to the traditional building method, this serves as a faster construction technique with less waste and a less negative environmental footprint. Prefab houses can be referred to in many ways, including prefabricated homes, modular houses, and modular homes.

Due to the nature of the requirements for prefab houses, the materials used need to meet criteria, such as stability and lightweight. However, not every single component of a building needs to be considered for prefabrication. Only specific elements that make up the bulk of a building’s construction and interior fittings can be prefabricated, such as walls, floors, roofs, closets, and shelving units.

Industrialization and mass production

Prefab homes can be mass-produced since the components can be constructed relatively faster than on-site building. This would represent a shift in the focus and infrastructure of building from producing raw materials such as cement, sand and I-beams, to producing modular components.

Speed and Affordability

Prefab homes are much cheaper than regular homes due to the amount of time spent and effort saved compared to traditional construction buildings. The time consumed is more often concentrated in making the components rather than in assembling them.

Customization and Sustainability

The design of prefab houses needs the components to fit in a way that allows for a reasonable degree of customizability. Furthermore, the processes employed in the construction and assembly need to have an as little environmental impact as possible.

Materials used in prefab Modular Buildings – Homes

Several materials are used in prefab homes, such as Concrete Board Panels, Rock wool Panels, and Steel structure. Here, we examine some of these materials and their efficacy of use.


-Low Thermal Conductivity
-Light Weight Materials
-Excellent Sound Insulation
-A Level Fireproof
-Long Life Span
-Faster Installation Time


The Rock Wool Wall sandwich panels with a mineral wool insulation core offer high fire resistance and thermal insulation properties. ROCKWOOL external wall insulation is central to developing energy-efficient walls, and meets modern code requirements by providing continuous insulation for residential, commercial and industrial buildings. … ROCKWOOL boasts excellent thermal performance both in winter and summer. Rock wool Sandwich Panels are composed of 3 layers, the external and internal is two dyed Galvanized or Aluminum corrugated plates, and core high-density Rockwool (Mineral Wool). Thanks to their properties the panels may be applied in an object that requires very high fire resistance, Rockwool sandwich panel is the most effective acoustic materials used on construction.

-Low Thermal Conductivity
-Thickness of insulation 75mm
-Excellent Sound Insulation
– High fire resistance
– Long Life Span
– Waterproof


A modular building is a pre-engineered steel structure, which means its components, or modules, are built in a factory set according to the same codes as any traditionally constructed buildings. The finished modules are transported by commercial trucks to a construction site, where they are assembled by a builder. Steel can be recycled and is so durable, and requires so little maintenance, it is a more economical choice for building owners.

Galvanizing is an industrial finishing process that provides corrosion protection to steel structures. By immersing structures in a bath of 450 °C molten zinc, structures adhere to several layers of zinc extending its life for many more years.


Glass is a highly customisable material for several building functions. Several types of glass are used in construction, including tempered glass, laminated glass, heat-strengthened glass, and wire glass. Glass can bring about useful properties, such as high strength, insulation, chemical resistance, and fire resistance. Glass also has a unique aesthetic quality and is fully recyclable, a common theme of prefab houses.
