Sandwich Wall Panel To Enhance A New Level Of Architecture

The sandwich panel offers various possibilities for different colors, textures and outer surfaces. Buildings with sandwich exterior wall panels can have very different appearances, depending on the formwork and raw materials used in the production of sandwich wall panels, the color of the wall panels and the exterior finish of the precast concrete sandwich wall panels. Ornamental themes and three-dimensional effects are becoming more and more popular in architecture, leading to the rise of new and innovative prefabricated production technologies.

Choose the right material and mold

The sandwich panel offers many possibilities to change the appearance, color, texture and architectural image. For any project, the best choice depends on the exterior needs of the building.

One point to consider is the materials used in the concrete mix. Which is better, white or gray cement? What is the natural color or size of the stone? These choices will determine the color and smoothness (or unevenness) of the appearance. The sandwich plate can also be colored in its entirety. In this case, color pigments need to be added to the mixture.

The table form produced by precast concrete wall panels determines the appearance of the surface. Ordinary table molds can create straight surfaces, but with the help of additional equipment, there are more options. Special molds can be used to create different shapes, patterns and textures. The mold can be made of wood, steel, rubber, plastic or silicone, and its contours are extremely diverse. The surface structure of the selected mold will also affect the perceived color of the wallboard. According to the architect's idea, the mold can be unique and tailored for a specific project.

The choice of rubber mold determines the shape of the surface, but it is equally important what lies below the surface. The steel table mold used to manufacture the prefabricated wall panels must be of high quality and must be straight and accurate in size-any bending or deformation of the table mold will cause the same defects in the prefabricated components.

Painting or exterior?

The prefabricated components can also be made of other materials, such as precious natural stone, ceramic tiles or facing tiles. Another option is to paint the wall with the desired color. The range of exterior wall finishes has recently expanded, and a variety of decorations are compatible with sandwich wall panels.

Fresh concrete is easy to process, and the final appearance of the wall panel can be obtained by treating its surface while the concrete is still plastic. For exposed aggregate concrete, the retarder should be sprayed on the surface of fresh concrete, and then the surface mortar should be removed by spraying with high-pressure water guns, thus creating a beautiful and stylish patterned concrete wall panel, including some exposed aggregate surfaces and some smooth surfaces .

Hardened concrete can also be processed. An example is sandblasted concrete. The depth of sandblasting can be shallow, moderate or deep. Mild blasting can only eliminate the gloss of the cement slurry, while the advanced treatment can almost completely remove the surface cement slurry. After deep blasting, the color and appearance of the wallboard mainly depend on the aggregate in the concrete.

Sandwich plates can also be polished and polished, or they can be chemically treated or polished to obtain specific colors, such as blue, turquoise, or shades.

Construction plan

Because the sandwich wall panels are factory-made, the doors and windows can be installed in the components, and the construction and installation can be carried out directly at the construction site. Installation requires a small number of cranes and workers, and no scaffolding is required. The size of the sandwich plate can be small or large, up to two layers high.

Sandwich wallboards can reduce costs because less manual work and surface treatment are required on site. The possibilities of different sandwich wall facades are endless.
