Compare 3 House Types: Prefabricated - Prefabricated - Module

Have you ever asked the question Prefab house - Modular house - Prefabricated house is different or not? If so, which one is the best? Does the price difference mean the quality is inferior to each other? Here are the answers to all the above questions.

Overview of the Prefab house

What is a prefab house ?

Prefab house is also known as container house , in addition, it is also known as mobile home . This model is composed of lightweight materials (smartboard cement, wood, brick, EPS lightweight concrete, ..) that functions like a normal house. Installed and designed according to the requirements of the owner.

Basic structure of a prefab house

The structure of a prefab house usually has frames, ribs, walls, partitions...

- House frame (columns, trusses): usually used materials of steel, galvanized u, house trusses will be linked with coded bolt columns.

- The roof will be used box steel, the roof sheet is made of corrugated iron with a thickness of 50-100mm.

- Roof gutters.

- The ceiling is artificial wood or heat-resistant cement panels to cool the house.

- The frame and ribs are carefully measured, the joints must be firm.

- Walls, partitions using 2 sides of corrugated iron, PU foam insulation, soundproofing.

- Anti-storm bracing, increase safety.

- Doors and windows are aluminum, glass, steel or panel doors depending on requirements.

Advantages and disadvantages of prefab houses

Advantages of prefab houses

- Save construction time

The construction and assembly phase of prefab houses is very simple and fast. Optimizing time a lot more than normal houses.

- Cost saving, economic efficiency

Because of the use of cheap and good quality materials, it is not necessary to spend too much money for this area, saving labor costs and when it comes to dismantling, changing the architecture is very simple and does not need to cost more. dismantling costs.

- High aesthetics

Existing prefab models are following the latest trends in building materials, bringing a modern architecture and a fresh feel.

- Easy to change, move

When the owner has a need to change the architecture, the structure of the house, the disassembly of the prefab house is very simple, it can be disassembled into each joint and stored in the warehouse, easy to reuse.

- Environmental friendliness

Since it is assembled from recyclable materials, there are no classical construction processes that limit health-affecting fine particles.

Disadvantages of prefab houses

- Lifespan is not too high

The durability of prefab houses can be up to 30 years, but still lower than ordinary reinforced concrete houses.

- Need a large area

It is still possible to assemble with small plots of land, but it needs a large enough space to move the materials of the prefab house and there is space to facilitate assembly.

Brief about Module House

What is a module house ?

Module house is a type of house that is built and assembled at the factory. From the interior - exterior are measured, carefully calculated to complete the house in the most accurate way. Once completed, the module house will be brought to the location where the house is to be installed. The time to install a house depends on the level of requirements of the owner but is usually very quick.

Basic structure of the Module house

Has a high-quality steel frame structure, creating stability. And there are systems like:

- System of columns: made of CT3 and U-steel materials, galvanized box.

- System of visors and partitions: using insulation materials, double-sided galvanized. Usually use heat-resistant foam or PU panels, good sound insulation. Insulation materials have 2 types (N - series) and (P - series).

- Corrugated iron roof system: usually use PE foam corrugated iron, PE layer has good effect of anti-heat, anti-fire, anti-moisture, anti-lightning Or there are other options such as bitumen roof, fake corrugated iron roof, to match the type of roof. construction.

- Anti-wind brace system ensures user safety.

- Doors and windows: made from xingfa aluminum materials, steel, or can be replaced with panel doors according to customer requirements.

- Gutter system: installed on the roof, has the effect of leading water to the outside to keep the interior space dry.

- Electrical system and ventilation system.

- There will be more furniture such as beds, cabinets, and home appliances that will be installed on request

The advantages and disadvantages of the Module house

Advantages of the Module house

- Save construction time quickly

The biggest difference compared to reinforced concrete houses is that the construction time of the Module house is very short, maybe only a few days or a few weeks depending on the requirements of the owner.

- Cost savings

When saving time, it also reduces the costs incurred such as labor, electricity, water.

- Reusable

Because of the use of materials that can be recycled many times, it can be folded for storage.

- Environmental friendliness

When using the module house form , it will limit fine dust that affects health, limit waste and environmental pollution.

Disadvantages of Module House

Module houses have one more limitation compared to other house models. When installing, it must be installed in the workshop, the water pipes and power lines must be completely assembled inside the non-removable Module wall panels.

Brief about prefab house ?

What is a prefab house ?

Prefabricated houses are also known as pre-engineered steel buildings. The structure of a house is made entirely of steel. Completed according to the pre-structured drawings and completely installed at the location required by the owner.

Structure of prefabricated house

The structure of a pre-engineered steel house includes the following basic parts:

- The house frame system (frame around the ribs, rigid frame for house construction, gable frame in the form of beams and pillars).

- Purlin roof and purlin wall.

- Bracing system, longitudinal struts, anti-storm bracing.

- Other systems: roofs, roofs, ventilation systems...

Advantages and disadvantages of prefab houses

Advantages of prefabricated houses

- Cost savings

Like the previous two models, when building a prefabricated house , it will be more cost effective than classic house models, but the price of this house model in general will not be as economical as a prefabricated house .

- Save time

The construction process of this house model is very fast, because the structures and joints of the prefabricated house have been carefully measured and handled at most stages at the workshop. Therefore, the construction process will be shortened.

- Has good bearing capacity

Assembled with solid steel bars, prefabricated houses can withstand storms that are not inferior to conventional reinforced concrete houses.

Disadvantages of prefab house

- Not recyclable

Unlike the two models above, the prefabricated house uses steel materials, so it will rust over time and cannot be reused.

- Poor fire resistance

When at a temperature of 500 - 600 degrees Celsius, the steel will melt into plastic, reducing its strength and easily collapsing.

Current prefabricated house models

So let's take a look at what is the top priority choice?

Basically, these types of houses are the optimal solution when building instead of building in the usual reinforced concrete architecture. But each type will have different limitations. Here is a specific comparison table for you to have a broader perspective.

Through the comparison table, it is easy to see that the prefab houses have better highlights than the other two types of houses. Therefore, the prefab house should be the first choice.
