The difference between exterior wall hanging board and exterior wall metal carved board
External wall hanging board and exterior wall metal carving board: two different concepts, external wall insulation and color aluminum board can not replace the external wall insulation decoration, XRY exterior wall energy-saving decoration integration and XRY exterior wall insulation decoration integration trend.
I. Definition difference: The former refers to the way of on-site construction (bonding, mechanical anchoring, pasting + mechanical anchoring, spraying, pouring, etc.) with a certain fixed method, and the thermal insulation with low thermal conductivity (good thermal insulation effect) An engineering practice in which the material is fixed to the wall of the building to increase the average thermal resistance of the wall to achieve insulation or heat insulation. The latter is to fully improve the former's drawbacks, so that the external wall insulation and decoration are perfectly combined, the factory production line production, hanging, pasting, anchoring to the wall, the construction is very simple and easy, it is offsite The way of construction, that is, the finished product of insulation products, the scientificization of energy-saving materials, and the industrialization of decorative products.
Second, the former is more common in the advantages and disadvantages of insulation materials, the latter contrast superiority:
1. Expanded polystyrene board (EPS board)
The thermal conductivity is 0.038-0.041. The heat preservation effect is good, the price is cheap, and the strength is slightly worse. The state has not advocated the use of such materials for heat preservation, and the traditional heat preservation has begun to turn to the era of traditional heat preservation.
2. Extruded polystyrene board (XPS board)
The thermal conductivity is 0.028-0.03. The thermal insulation effect is better, the moisture resistance is expensive, and the surface needs to be treated during construction. This is a problem left by the traditional thermal insulation. The practice time of the external wall hanging board has no external wall insulation decoration integration, that is, the energy saving decorative board curtain wall time. Long, need further argumentation.
