Silicon Rock Panel functions as an eco-friendly construction material which creates its structure by fusing inorganic silica with high-strength reinforcing fibers. This material displays characteristics like weight reduction and superior strength and fire resistance alongside waterproof and fungus-resistant features as well as durable weather endurance. This building material finds extensive usage throughout building exterior walls along with interior wall decoration applications and partition panels and building ceilings. The unique characteristics of Silicon Rock Panel include its visually flexible designs alongside material-like aesthetic effects and its efficient construction properties alongside reduced building weight.

What are the advantages and disadvantages of Silicon Rock Panel over other Sandwich Wall?

Advantages of Silicon Rock Panel

1. Superior fireproof performance

The fireproof grade reaches Class A, i.e. completely non-combustible, which can effectively stop the spread of fire.

Compared with flammable materials such as PU boards and EPS (polystyrene) boards, it is much safer.

2. Stable structure and high compressive strength

Adopting inorganic silica rock mineral filling, the overall structure is stable and not easy to deform.

With strong impact resistance, it can meet the demand of high strength load, and is suitable for industrial plants and steel structure buildings.

3. Good insulation and heat preservation performance

Silica rock panels have a low thermal conductivity (about 0.035~0.045 W/m-K), which provides good thermal insulation and heat preservation in both winter and summer seasons.

Compared with rock wool board, it is more water-resistant and stronger, although its thermal insulation performance is slightly inferior.

4. Strong weather resistance and long service life

Composed of inorganic materials, it is not easy to age, has strong UV resistance and stable performance in various climatic conditions.

Compared with PU boards, EPS boards or other Roof Sandwich Panels, it has a longer service life and will not produce significant deformation or degradation due to the external environment.

5. Green environmental protection, safe and non-toxic

Silica board does not contain harmful gases and does not release toxic fumes when burning at high temperature.

There is less dust in the construction process, which is in line with environmental standards.

Disadvantages of Silicon Rock Panel

1. Insulation performance is not as good as PU board

The thermal conductivity of silica rock panels is higher than that of PU panels (about 0.018~0.025 W/m-K for PU panels), and the thermal insulation effect may not be as good as that of PU panels in extremely cold areas.

For applications with very high thermal insulation requirements (e.g. cold storage), it may be necessary to increase the thickness or use additional insulation.

2. Higher weight and construction requirements

Silica rock panels are denser and heavier compared to lighter materials such as EPS panels and PU panels.

It needs stronger structural support, while transportation and installation are more difficult, increasing construction costs.

3. Relatively high construction cost

Higher material cost due to complex manufacturing process, higher initial investment compared to PU boards, EPS boards, etc.

Suitable for long-term use of the building, but short-term projects may not be cost-effective.

4. Lower flexibility, not easy to cut and process

Due to the hard material, it is more difficult to cut and adjust during construction, not as flexible as PU board and EPS board.

Suitable for standardized large-area installation, but less friendly to complex shaped structure construction.

Summarize

Silicon Rock Panel of the Aluminum Sandwich Panel Roofing is suitable for buildings with high requirements for fire safety, strength and weather resistance, such as industrial plants, steel buildings, commercial complexes and so on.

Not suitable for places with high requirements for extreme heat preservation, lightweight structure and low cost, such as cold storage, temporary buildings, etc.
