Which houses can use sandwich panels for external wall insulation? Generally speaking, there are three types, let’s talk about them today!
Brick wall load-bearing, called brick-concrete structure Brick-concrete structure refers to the wall of the vertical load-bearing structure in the building using bricks or blocks, and the wall, floor, and roof of the structural column and horizontal load-bearing beam adopt reinforced concrete structure. The material is easy to use and the construction is simple, which is in aligns with theon in rural areas. Polyurethane foam is in the middle of the metal engraving board exterior wall insulation board to form thermal insulation. The broken thermal layer and its interior are independent closed-cell structures. The aluminum foil on the back can effectively reflect the heat source and keep it warm. The construction of the concave-convex buckle groove structure is very simple.
2. Concrete beam-column load-bearing is called frame structure. The frame structure makes the indoor space larger, which can meet the complex building form, the earthquake resistance is slightly stronger, and the room partition wall can be removed and replaced at will. The outer layer of the metal engraving board external wall insulation board is the aluminum galvanized board, the board is connected with a gusset plate connection, seamless, polyurethane foam protection, low water absorption, excellent moisture, and seepage resistance, very suitable for frame structure.
3. Steel columns and steel beams are load-bearing, called steel structures. Advantages of steel structures: lightweight, fast construction speed, energy saving, and environmental protection, good sound insulation performance, and durability. Its height can reach more than 500 meters. Due to its flexible structure, it is less affected by earthquake destructive force. In foreign countries, it is called metal engraving board "century board". The reason why it is called century board is because of its long service life. The appearance color is not affected by the harsh environment and always maintains a new appearance. Excellent basic characteristics, and thermal insulation performance.
