Should you choose fiber cement boards or load-bearing plastic boards for your mezzanine floor?

Cement fiberboard (Cemboard) and load-bearing plastic panels are two modern material solutions used to replace traditional concrete floor pouring methods in the construction of mezzanine floors, floating house floors, prefabricated house floors, and modular house floors. These materials are lightweight, quick to install, and meet the requirements for safe load-bearing capacity for the structure.

Fiber cement boards are composed of Portland cement (70%), fine silica sand, and cellulose fibers, with a load-bearing capacity of 800-1300 kg/m² depending on thickness. This material reduces pressure on foundations and columns by 33% compared to concrete pouring, while weighing only 67% of traditional concrete. Standard board dimensions are 1220mm x 2440mm, with thicknesses ranging from 14-20mm, and prices ranging from 305.000 to 625.000 VND/board (as of November 2025). However, this is a raw material requiring surface finishing after installation.

Load-bearing plastic panels use a composite core material (40% plastic and 60% stone powder/additives), resulting in a lighter weight of only 12,5 – 17,5 kg/m² with dimensions of 333 x 23 x 3000-4000 mm. Load-bearing capacity reaches 500 – 1100 kg/m² with a frame system ≤400 mm. Key advantages include quick installation using a tongue-and-groove system, aesthetically pleasing wood grain patterns, termite resistance, water resistance, and a lifespan of up to 15 years. Material cost ranges from 500.000 – 730.000 VND/panel.

The choice between the two materials depends on the specific application. Fiber cement boards are suitable for high-load bearing structures such as warehouses and factories due to their excellent load-bearing capacity. Meanwhile, load-bearing plastic boards are the optimal choice for spaces prioritizing aesthetics and construction speed, such as dorm rooms and houses, with the advantage of being a ready-to-use finishing material requiring no further processing.

Load-bearing plastic sheets, with a composition of approximately 40% plastic and 60% stone powder/additives, are a new generation of finishing materials capable of withstanding loads up to 1.100 kg/m² and an estimated lifespan of 15-20 years (depending on construction conditions and environment). According to Mr. Nguyen Minh Khoa, a finishing materials expert and member of the Vietnam Building Materials Advisory Network.

What are fiber cement boards used for mezzanine flooring?

Fiber cement board (Cemboard) is a large-format sheet material specifically used as a base layer for mezzanine floors.The product is composed of Portland cement, cellulose fibers, and fine silica sand. It is an alternative to traditional concrete pouring while still ensuring a load-bearing capacity of 800-1300 kg/m².

This product effectively meets the need for a strong yet lightweight floor, reducing the pressure on foundations and columns by 33% compared to pouring concrete. Fiber-reinforced cement boards have low expansion (0,01 – 0,07%), ensuring dimensional stability and minimizing warping over time.

Weighing only about 67% as much as concrete, this material optimizes structural load and reduces construction time by 50%. This is a key factor in old house renovation or factory construction projects.

After installing the fiber cement boards for the mezzanine floor, you need to perform additional surface finishing steps (such as tiling, vinyl flooring, or painting) to ensure aesthetics and long-term functionality.

The price of fiber cement boards for mezzanine flooring ranges from 305.000 to 625.000 VND/board (updated November 2025). The standard board size is 1220mm x 2440mm, with a thickness of 14mm to 20mm.

What are load-bearing plastic panels for mezzanine flooring?

Load-bearing plastic sheets are a groundbreaking solution for constructing mezzanine floors, attic floors in rental rooms, floating house floors, and prefabricated houses.The product is made from a composite material core (40% resin and 60% stone powder/additives).

The lightweight material, weighing 12,5kg/m² – 17,5kg/m², comes in panels measuring 333 x 23 x 3000mm – 4000mm, optimizing the building's load-bearing capacity. The load-bearing capacity of the mezzanine floor panels ranges from 500 – 1100kg/m² with a frame thickness of ≤400mm.

Using durable plastic panels for mezzanine flooring allows for quick installation with a click-lock system, reduces fine dust, resists termites, and is waterproof. The material has a fire resistance rating of B1, B2, effective scratch resistance of AC3, AC4, reduces slipperiness, and is easy to clean.

The product is manufactured in various lengths such as 3000mm, 3500mm, and 4000mm. This minimizes the need for cutting and joining floorboards, creating a seamless and aesthetically pleasing surface for interior spaces. The material has a lifespan of up to 15 years and comes with accessories such as skirting boards and V-shaped edge trims.

The material cost for load-bearing plastic sheets for mezzanine flooring ranges from approximately 500.000 to 730.000 VND per sheet, as of November 2025.

Should you choose fiber cement boards or load-bearing plastic boards for your mezzanine floor?

Choose fiber cement boards when high load-bearing capacity is required (warehouses, factories), and choose load-bearing plastic boards when aesthetics and quick installation are prioritized. Below is a detailed analysis to help you make the right decision.

Frequently Asked Questions about Load-Bearing Flooring Materials

What should be considered when installing plastic sheets for load-bearing flooring?

When installing plastic sheets for load-bearing flooring, there are 7 things to keep in mind.:

1. Do not place items that exceed the floor's weight capacity.
2. Frame materials: Square iron tubing, galvanized steel, stainless steel. Frame dimensions: 40x80mm, 50x100mm, 60x120mm. Frame thickness: ≥1,4mm
3. Distance between two bones: ≤400mm
4. After welding, the welds need to be sanded smooth and coated with anti-rust paint to increase the durability of the frame.
5. Apply construction adhesive directly to the frame for assembly. The adhesive must be applied continuously to each plank to ensure it does not dry before installing the floor.
6. The extension points at both ends of the floor beam are fixed to the frame.
7. When laying multiple rows of flooring, it is necessary to stagger the rows to distribute force effectively and avoid weak points at the joints.
