How to choose the materials of the wall and roof
The hollow brick wall and the sandwich panel wall are two different methods of wall construction. The hollow brick wall is made of hollow bricks and is commonly used for interior partition walls. It is characterized by good sound insulation and heat insulation, and has relatively low costs. The sandwich panel wall is composed of two layers of panels and a core material in the middle. It has strong integrity, is easy to install, has good heat insulation and heat preservation effects, and is often used in light steel structure buildings, but its cost is relatively higher.
Hollow Brick Wall
Advantages: Good sound insulation and heat insulation effects, relatively low cost, easy to construct.
Disadvantages: Compared with the sandwich board wall, the wall is thicker, but the load-bearing capacity and seismic resistance are relatively weaker.
Sandwich Panel Wall
The sandwich panel wall is a new type of building material. It is composed of two layers of panels (usually steel
plates, aluminum plates, etc.) sandwiched between a middle insulation core material (such as rock wool, EPS
foam, polyurethane, etc.). Its main features are integrating functions such as insulation, heat insulation, sound
insulation, and fire resistance. The construction speed is fast, and it is suitable for the roofs, exterior walls, or
interior partition walls of large public buildings, factories, and warehouses.
Sandwich Panel Wall Core structure and materials
Panel: Usually made of steel plates or aluminum plates, which have high strength and corrosion resistance.
Core material: The insulation material filled in the middle. Common ones include:
EPS (Expanding Polystyrene) sandwich panel: Good heat insulation and sound insulation effects, with relatively low cost.
Rock wool sandwich panel: Excellent fire resistance, and it is a fire-resistant material certified by the Ministry of Construction of
the Interior Department.
Polyurethane (PU) sandwich panel: Excellent insulation performance.
Sandwich Panel Wall Main advantages
Insulation and heat insulation: The core material can effectively reduce indoor temperature fluctuations and
reduce cooling and heating costs.
Sound insulation and noise reduction: The sound-absorbing performance of the core material can effectively
reduce noise.
Fire resistance: Some core materials (such as rock wool) can reach the fire resistance duration certification of
the Ministry of Construction of the Interior Department.
Fast construction: Dry hanging construction is adopted, with few fixing parts and convenient installation,
improving construction efficiency.
High aesthetic quality: The surface can be processed by various coating treatments (such as water transfer
printing, PVDF baking paint, etc.), meeting the aesthetic requirements of different buildings.
Good durability: Has anti-corrosion, anti-humidity, and strong wind resistance characteristics, with a long service
life. Application scenario
Roof and exterior wall system: Suitable for the exterior walls and roofs of various industrial plants, warehouses,
and public buildings.
Interior partition wall: Can be used as an interior partition wall, saving space and having sound insulation and
heat preservation effects.
Composite board product introduction: Also known as sandwich panel, it is made by using two layers of steel
plates as the panel and backboard, with an inorganic insulation material sandwiched in the middle for composite
production. It has remarkable insulation and...

together
Disadvantages: Higher cost, not suitable for load-bearing walls.
How to choose
If you prioritize economy and sound insulation and heat insulation performance, and the wall does not need to bear weight: You can choose the hollow brick wall, such as the interior partition wall.
If you pursue lightness, easy installation, good heat insulation, and are in a light steel structure building: You can choose the sandwich panel wall.
