Mortar polyurethane insulation board is a kind of efficient insulation material, which combines the advantages of polyurethane insulation performance and the protective and strengthening characteristics of mortar.

Structural composition

Polyurethane core: Polyurethane is the core part of the insulation board. The polyurethane material itself has an extremely low thermal conductivity, generally between 0.022-0.024 W/(m · K), which allows it to effectively prevent the conduction of heat. Its internal structure is closed cell structure, and these closed holes can effectively reduce the convection of air and further enhance the insulation effect. Moreover, polyurethane material also has good flexibility and compressive strength, and can withstand a certain degree of external force without deformation.

Mortar layer: On both sides (or one side) of the polyurethane core material composite mortar layer. The mortar layer mainly protects the polyurethane core material and prevents it from being damaged by external environmental factors (such as ultraviolet light, wind and rain erosion, etc.). At the same time, the mortar layer can enhance the overall strength of the insulation board, making it more stable during installation and use.

Thermal insulation

High efficiency and energy saving: the insulation performance of mortar polyurethane insulation board is excellent, and its low thermal conductivity can effectively reduce heat transfer. In building applications, it can significantly reduce the heat loss of buildings in winter and heat absorption in summer, thereby reducing the frequency of heating and air conditioning use, reducing energy consumption, and achieving the goal of energy conservation and emission reduction. For example, a building using mortar polyurethane insulation panels can reduce energy consumption in heating and cooling by about 30-50% compared to a building that does not use highly efficient insulation materials.

Thermal insulation lasting stability: due to the closed cell structure of polyurethane and good chemical stability, as well as the protective effect of the mortar layer on the thermal insulation core material, the thermal insulation performance of this thermal insulation board can be maintained for a long time. It will not be like some traditional insulation materials, because of long-term use, moisture or physical extrusion and other factors, the insulation performance is significantly reduced.

Structural properties

High strength and stability: the mortar layer enhances the overall strength of the insulation board, making it have good compressive and flexural properties. After installation on the exterior wall or roof of the building, it can withstand various loads, such as its own weight, wind load, snow load, and pressure generated by personnel activities and equipment placement. This makes the use of thermal insulation board in building structures more safe and reliable, and can maintain a stable state in the complex building environment for a long time to reduce the risk of thermal insulation system failure caused by structural deformation.

Accurate size and easy installation: mortar polyurethane insulation board is usually strictly controlled in the production process of dimensional accuracy, its edge neat, uniform thickness. This not only facilitates cutting and splicing in building construction, but also helps to ensure the integrity and tightness of the insulation system. The construction personnel can accurately install the insulation board according to the actual needs, reduce the error in the construction process, and improve the construction efficiency.

Waterproof and moisture-proof

Excellent waterproof performance: the hydrophobic and closed cell structure of polyurethane makes it itself have good waterproof ability, coupled with the outer mortar layer to further enhance the waterproof effect. This dual waterproof guarantee makes the insulation board can effectively resist the water penetration generated by rain, snow and condensation inside the building, and avoid moisture in the insulation core material. For example, in the roof insulation system, the mortar polyurethane insulation board can effectively prevent rain from penetrating into the insulation layer, protect the roof structure at the same time, but also ensure the long-term stability of the insulation performance.

Moisture-proof and mildew proof: Because it can prevent moisture from entering, the mortar polyurethane insulation board can effectively prevent moisture and mildew inside the insulation layer. In a humid environment, mold breeding will cause damage to the insulation material and building structure, and the waterproof and moisture-proof characteristics of this insulation board can avoid such problems and extend the service life of the insulation system and building structure.

Fire safety

High fire rating: By adding flame retardants and other measures, the mortar polyurethane insulation board can reach a higher fire rating, such as B1 (flame retardant) or even A2 (non-combustible). In the event of a fire in a building, it can effectively delay the spread of the fire and gain valuable time for personnel evacuation and fire rescue. This is of great significance for improving the fire safety performance of buildings, especially in densely populated residential, commercial and public buildings.

Good combustion performance: Even in the fire environment, some excellent quality mortar polyurethane insulation board also has the characteristics of self-extinguishing from the fire, further reducing the risk of fire. This combustion performance enables the thermal insulation board to self-control the combustion process in the early stage of the fire and reduce the loss caused by the fire.

Durability and service life

Strong weather resistance: it can withstand the influence of natural factors such as ultraviolet radiation, temperature change, wind and rain erosion. Whether it is in the cold northern region or the hot and humid southern region, it can maintain stable performance for a long time. Its aging resistance is good, it will not be quickly damaged because of long-term exposure to the outdoor environment, and it can provide lasting insulation, waterproof and fire protection and other functions for the building.

Long service life: Considering its thermal insulation performance, physical properties, waterproof and fireproof performance and weather resistance and other advantages, mortar polyurethane insulation board has a long service life. Under normal circumstances, its service life can reach 25-30 years or even longer, compared with some traditional thermal insulation materials, reducing the cost and resource waste caused by frequent replacement of thermal insulation materials.

Environmental and economic aspects

Environmental protection characteristics: In the process of production and use, mortar polyurethane insulation board is relatively environmentally friendly. The polyurethane material itself is a recyclable material, and its excellent performance in heat preservation and energy saving also helps to reduce the energy consumption of buildings during use, indirectly reducing carbon emissions. At the same time, some manufacturers will also pay attention to environmental protection standards in the production process to reduce environmental pollution.

Affordable: Although the initial procurement cost of mortar polyurethane insulation board may be slightly higher than some traditional insulation materials, its excellent performance can reduce long-term energy consumption costs, maintenance costs and replacement costs. From the perspective of the whole life cycle of the building, it is an affordable insulation material choice. For example, by reducing energy consumption, the cost difference caused by slightly higher material prices can be recouped within a few years, and there are continued savings in subsequent use.
