As shown in the comparison table, multiple key components have been upgraded with higher-grade materials. These improvements significantly boost the unit’s thermal insulation performance, structural stability, overall living comfort and long-term service lifespan. We will walk you through each major upgrade in detail below.

Exterior Wall Panels: EPS wall panels VS metal carved wall panels

The F20 comes with 65mm EPS wall panels for its exterior walls, whereas the upgraded variant features 16mm metal carved PU composite panels. What exactly sets these two wall panel options apart? We will first introduce each material individually before drawing a detailed comparison between them.

What are EPS wall panels?

EPS wall panels are lightweight sandwich panels consisting of an Expanded Polystyrene (EPS) foam core bonded between two rigid metal sheets. This composite structure offers excellent thermal insulation and structural rigidity, making them a widely used wall cladding solution for prefabricated buildings.

What are metal carved wall panels? 

Metal carved wall panels come with a structure similar to sandwich panels, but they are different. Metal carved wall panels are composite wall panel, consist of protective coating, embossed metal surface, Polyurethane(PU) insulation core, and aluminum foil. This layered design delivers superior thermal insulation, waterproofing, corrosion resistance, and decorative effects compared to conventional wall panels.

Which is better?

In terms of thermal insulation, polyurethane (PU) outperforms EPS by a noticeable margin. Even a 16mm-thick PU panel provides superior heat preservation compared to a 65mm-thick EPS panel. For example, imagine a thin down jacket (PU panel) is to a heavy cotton coat (EPS panel). If your project is situated in extremely hot or frigid regions, insulation performance should be your top priority.

When it comes to appearance, the embossed texture of metal carved panels offers a far more premium aesthetic. If you plan to use the expandable unit as a guest house or rental accommodation, metal carved wall panels will greatly enhance its visual appeal.

From a cost-performance perspective, EPS wall panels come at a more budget-friendly price point.

 Insulation Layer: Graphite EPS VS Conventional EPS

For interior wall panels, our standard models adopt 50mm-thick EPS color-coated steel sheet, while the pro version uses 50mm-thick carbon fiber graphene EPS integrated board. The core performance gap mainly comes from the different EPS insulation materials used.

What is Conventional EPS?

Conventional EPS is made of pure polystyrene particles through thermal foaming, forming a white closed-cell foam structure. It achieves basic thermal insulation by trapping static air inside dense air bubbles, with a thermal conductivity of 0.036~0.039 W/(m·K). The lower the thermal conductivity value, the better the heat preservation performance.

As a cost-effective insulation material, conventional EPS is budget-friendly. However, it cannot reflect infrared heat radiation, resulting in faster internal and external heat exchange and weaker temperature locking capability.

What is Graphite EPS?

Graphite EPS is an upgraded modified foam infused with high-purity graphite particles, presenting a unique silver-gray appearance.

The embedded graphite particles act as countless micro reflective mirrors to block infrared heat radiation, effectively reducing heat transfer. It features outstanding thermal insulation.

Which perfoms better?

Except for material cost, graphite EPS outperforms conventional EPS in thermal insulation, structural stability, and overall durability.

Thermal Insulation

Graphite EPS provides around 30% better insulation than conventional EPS at the same thickness. It effectively retains indoor heat in winter and blocks outdoor high temperatures in summer, greatly reducing air conditioning and heating energy consumption for resort cabins.

Cost

Conventional EPS features lower material cost and serves as the standard configuration for basic models. Graphite EPS comes with a higher raw material premium and is offered as an upgraded optional configuration.

Climate Adaptability

Conventional white EPS fully meets the usage demands of tropical and subtropical warm climates. For snowy, freezing regions and high-altitude camps, graphite EPS is strongly recommended for reliable thermal performance throughout the year.

Durability & Fire Resistance

Graphite EPS boasts a more stable physical structure with better resistance to thermal deformation. It also delivers superior flame-retardant performance compared to conventional EPS, ensuring safer and longer-term service.

 SPC Flooring VS PVC Flooring

SPC flooring delivers significantly better waterproof performance compared to ordinary PVC flooring, making it a more reliable option for prefab houses and humid environments.

What is SPC Flooring?

SPC flooring adopts a durable three-layer integrated structure formed through high-temperature hot-melt pressing technology. It is water-resistant, flexible, and features zero formaldehyde emission. It also boasts unique anti-slip performance: instead of becoming slippery when wet, it gains stronger friction, greatly improving walking safety.

What is PVC Flooring

PVC flooring, also known as polyvinyl chloride flooring, is an eco-friendly decorative material. It is 100% free of toxic substances such as formaldehyde and benzene, and produces no radiation, causing no harm to the human body.

Which is better?

The core differences between SPC and PVC flooring lie in hardness, structural stability and installation methods. The better option depends on your application scenarios, budget and actual demands.

Structural Stability: SPC Flooring Is More Reliable

PVC flooring is sensitive to temperature and humidity changes. It tends to expand or contract under varying environmental conditions, which easily causes warping and deformation, leading to higher long-term maintenance costs.

In comparison, SPC flooring features high hardness, outstanding scratch resistance and exceptional structural stability. It is 100% waterproof and rarely deforms or warps under daily use.

Installation method

SPC flooring adopts a convenient click-lock installation system, enabling fast, easy and glue-free assembly.

On the contrary, traditional PVC flooring requires glue bonding during installation. Many low-cost suppliers opt for inferior adhesive that contains harmful residual substances, posing potential risks to indoor environmental health.

 Upgraded Waterproofing

Placed outdoors, waterproof treatment for housing units is a critical consideration. We apply differentiated waterproof construction processes to our standard and upgraded models respectively.

The upgraded waterproofing system adopts non-woven fabric combined with three layers of Oriental Yuhong waterproof material, which delivers remarkably boosted waterproof performance. By contrast, most competitors merely seal gaps and apply just one single layer of waterproof coating.

 Upgraded Bathrooom

We have also fully upgraded the bathroom configuration, with improvements mainly to the floor drain, wall and floor tiles and other key parts.

The upgraded bathroom comes equipped with anti-slip floor tiles and carbon crystal wall panels.

 Bottom Line

In short, the F20 Pro meets the requirements of a wider range of projects, greatly extending the building’s service life and elevating overall living experience. Meanwhile, the standard F20 model boasts an unbeatable price advantage, making it an ideal pick for short-term housing solutions.

We hope this comparison helps you pick the most suitable option for your needs.
