bright colors, beautiful appearance, wear-resistant, pressure-resistant, sun-resistant, never fades, and can create different structural effects.
Flexible Porcelain (Flexible Sheet) Series
Diverse appearances and shapes, realistic stone-like effect, lightweight and flexible, crack-resistant and earthquake-resistant, good weather resistance, high safety, and belong to environmentally friendly and ecological building materials.
Images showcasing the stone-like effect of ceramic thin slabs: the similarity of the exterior finish is over 95%.
Ceramic thin slabs are fired under 6000 tons of pressure and 1200 degrees Celsius, possessing the outstanding advantages of being thin, large, light, and hard.
The water absorption rate of ceramic thin slabs is less than 0.03%, achieving double-zero waterproofing, which is superior to the waterproofing performance of natural stone. Compared to dry-hanging stone, ceramic thin slabs not only have heavier panels, but the porous nature of natural stone is also detrimental to the waterproofing of rock wool systems, especially in high-rise building projects. Currently, ceramic thin slabs have become the preferred material for decoration companies seeking individuality and quality.
Product Features
Thin decorative panels offer rich decorative effects.
A variety of finishing materials are available to meet the personalized needs of different architectural styles.
Double protection with adhesive and anchoring ensures high safety.
Adhesive is the primary method, with anchoring as a secondary method; no anchoring should be done at the expense of bond strength.
Excellent mechanical properties.
Utilizing the excellent self-adhesive properties of polyurethane, the flowing liquid polyurethane penetrates into the rock wool in molecular form, forming a penetrating physical bond, resulting in a 100% cavity-free connection and improved mechanical properties of the rock wool.
Cavity-free interface layer prevents detachment.
The insulation layer, protective layer, and finishing layer of the thermal insulation decorative panel system are prefabricated in the factory, ensuring a 100% cavity-free structure.
Simple operation, fewer construction steps, and short construction cycle.
The insulation layer and decorative layer are applied in one go, requiring fewer trades, simplifying the process, and shortening the construction cycle, thus reducing labor costs.
The three-layer waterproofing system offers excellent waterproofing performance.
The joints between the panels in the thermal insulation and decorative panel system are the most vulnerable areas for thermal bridging and waterproofing. To address this issue, we developed a low-expansion, easy-to-use polyurethane sealant. After construction, all the thermal insulation and decorative panels will be connected as a whole, which improves the system's waterproofing performance and prevents thermal bridging.
Product Comparison
PRR Insulation Decorative Board VS Ordinary Rock Wool Insulation Decorative Board
| Project | Wanhua PRR Insulation Decorative Board | Rock Wool Insulation Decorative Board on the Market |
| Production Process | Continuous method / Microporous infiltration self-adhesive foaming / High production efficiency and capacity: 2500m² per shift, single line, 8 hours | Adhesive bonding method / intermittent / low production efficiency; capacity: 800m2 in 8 hours |
| Backing Material | Cement-based reinforced roll material | Calcium silicate board |

| Lining features | A thickness of 0.45mm reduces the weight of the insulation board, facilitating handling and transportation, and provides good safety. | A thickness of 4mm increases the weight of the insulation and decorative panel system and results in lower shear strength. |
| The embedded reinforcing mesh effectively disperses stress and inhibits deformation of the insulation board. | However, it has high water absorption, low water resistance and freeze-thaw resistance, and poor compatibility between the calcium silicate board and the bonding mortar, making it prone to detachment. | |
| The material is composed of emulsions and other materials, has low water absorption, high water resistance and freeze-thaw resistance, and good compatibility with mortar. | However, it cannot effectively disperse the ground stress caused by thermal expansion and contraction of the insulation decorative board. Some manufacturers alleviate this by drilling holes, and the strength decreases during freeze-thaw cycles. |
