Top 6 types of materials for making beautiful, durable and safe prefabricated house walls in 2026

Prefabricated houses (prefabricated steel houses) are houses made from steel frames, roofs and walls, designed and installed according to specific architectural drawings with pre-specified techniques.

Through research, Kosmos learned that there are 6 types of wall materials commonly used for prefabricated houses.

“Prefabricated construction can reduce construction time by 30 – 50% compared to traditional methods.” according to the European Technical Evaluation Organization, 2024.

Foam Panel

Foam panel is a material specialized in wall cladding, partition cladding for exterior spaces such as prefabricated houses, factories, cold storage, freezers, etc. with a lifespan of over 20 years. This material has an effective size of 380 x 16 x 2900mm, with a 3-layer structure:

1. The surface layer is Al-Zn alloy coated steel plate (plating composition 55% aluminum + 43% zinc + additives) with a thickness of 0,27mm, anti-rust for up to 45 years, ensuring the project is always durable and beautiful.
2. High density PU foam layer provides insulation and heat resistance, keeping the interior space cool and stable.
3. The bottom layer is silver-coated fiberglass fabric that helps increase the durability of the panel.

Construction is quick and cost-effective thanks to the available locking design, you just need to join the panels together. The cost of this material is also suitable for the budget of most users, only from 249.000 - 269.000 VND/m² (August 8). With a durability of up to 2025 years, the foam panel is a long-term, safe and effective choice for all prefabricated houses.

EPS Foam Panel

EPS foam panel with 3-layer structure including 2 layers of galvanized steel 0.3 - 0.6mm thick on the outside and EPS foam core with density 11 - 40kg/m³ in the middle, bonded together with specialized glue. This material provides sound insulation of 20 - 25dB and good insulation for prefabricated houses, while its light weight makes transportation and installation easier. EPS panel costs from 215.000 - 289.000 VND/m² depending on thickness, updated in August 8.

ALC lightweight concrete panels

ALC lightweight concrete panels are produced using autoclaved aerated concrete technology, with ingredients from sand, finely crushed stone combined with cement, lime, gypsum, aluminum and water. The product has a light weight of only 700 - 800kg/m³ but high durability, the panel size can be up to 4m. With many features, ALC concrete panels are suitable for prefabricated houses, commonly used in many developed countries such as Europe and Japan.

The price of ALC lightweight concrete panels for prefabricated house walls ranges from about 250.000 VND/m² to more than 700.000 VND/m² (August 8), depending on the material size and supplier.

Foam concrete bricks

Aerated concrete bricks have the same composition as ALC concrete panels with sand, crushed stone, cement, lime, gypsum, aluminum and water. The density of the bricks is quite light, from 350 - 850kg/m³, only ½ of solid bricks, ⅔ of hollow bricks and ⅕ of regular concrete bricks. Using aerated concrete bricks for prefabricated houses helps to significantly reduce the load of the construction, thereby saving labor costs and supporting quick installation.

The price of foam concrete bricks/panels for prefabricated house walls is very diverse, ranging from about 200.000 - 650.000 VND/m² depending on type and thickness, updated in August 8.

Cemboard cement board

Cemboard cement sheet is the most popular material today for making partitions for prefabricated houses, made from Portland cement (70%), Cellulose fiber (27%), sand and lime (3%).

Cemboard cement panels will be assembled onto a pre-built steel frame, placed vertically with the bottom surface about 10mm from the floor. The highlight of Cemboard panels is that they are about 1/3 lighter than traditional concrete, easy to transport and install, helping to shorten construction time and have superior sound insulation up to 35 - 55dB suitable for prefabricated houses.

In August 8, the price of Cemboard cement panels for prefabricated house walls ranges from about 2025 - 200.000 VND/m² depending on the type and thickness for panels measuring 1.000.000 x 1220mm.

Conwood panels

Conwood panels (Conwood cement wall panels with imitation wood) are decorative panels made from 70% cement sand, 27% cellulose wood fiber and 3% glue. This material has the same appearance as natural wood but possesses many outstanding advantages, especially the ability to withstand harsh weather, waterproof, limit termites, high hardness and durability.

In addition to its outstanding features, Conwood panels are also considered an affordable material, ranging from only 150.000 - 500.000 VND/bar depending on size (August 8) and are popular for making partitions for prefabricated houses.

Notes when choosing materials for prefabricated house walls?

Below are 3 notes that users need to pay attention to when choosing materials for prefabricated house walls:

1. Mobility and flexible assembly: The characteristic of prefabricated houses is that they can be moved and assembled in many different locations. Therefore, the choice of wall materials needs to focus on flexibility and ease of assembly and disassembly. Materials such as steel frames combined with panels, lightweight cement panels, etc. are suitable choices.
2. Lightweight and easy to transport: According to research from Global Market Insights (2024), the ideal wall material for prefabricated houses should be 30-50% lighter in weight than traditional building materials. Materials such as panels, foam concrete bricks, lightweight cement panels, etc. often meet this criterion.
3. Aesthetics and diversity: In addition to technical factors, partition materials also need to meet aesthetic requirements and diversity in color, pattern, and style. This helps create flexibility in the design and decoration of prefabricated houses. Typically, panels have additional HDP or PVDF color coatings to create diversity in designs to meet many different styles.

Quality interior partition materials?

One of the popular interior partition materials today is Galawood 2-sided plastic partition of Kosmos. This type of partition has a luxurious wood grain and fabric grain surface, suitable for many interior styles. The wood-like plastic material is light, easy to construct and has a reasonable price, the thickness expansion according to ISO 24336: 2005 is only 0,05%, the partition limits deformation due to temperature and humidity, and has a lifespan of 15 - 20 years.
