Why has thermal insulation mortar not been replaced in the modern construction industry?
Thermal insulation mortar It is a type of inorganic thermal insulation building material that is widely used in the modern construction industry. Compared with other inorganic insulation materials, thermal insulation mortar possesses unique characteristics of its own, which are mainly reflected in the following key aspects:
1. Inorganic thermal insulation mortar exhibits excellent thermal stability and chemical stability: The inorganic thermal insulation mortar system is composed entirely of inorganic materials. It is resistant to acids and alkalis, highly corrosion-resistant, crack-free, non-delaminating, and boasts superior stability, with no risk of aging—ensuring a service life equal to that of the building wall itself.
2. Simple construction and low overall cost: The inorganic thermal insulation mortar system can be applied directly to the bare wall, using the same application methods as cement-sand screed. The equipment and tools required for its installation are straightforward, making construction convenient. Compared with other thermal insulation systems, this solution offers a significantly shorter construction period and easier quality control.
3. Wide applicability and elimination of thermal bridges: The inorganic thermal insulation mortar system is suitable for a variety of wall substrate materials and for insulating walls with complex shapes. It provides a fully enclosed, seamless, cavity-free insulation layer that eliminates thermal bridges. Moreover, it can be used not only for external wall external insulation but also for internal wall insulation, or for simultaneous external and internal insulation; it can also be applied to roof insulation and underfloor heating insulation layers, thereby offering considerable design flexibility for energy-saving systems.
4. Green, environmentally friendly, and pollution-free: The inorganic thermal insulation mortar system is non-toxic, odorless, and free from radioactive contamination, posing no harm to the environment or human health. Moreover, its large-scale promotion and application can utilize industrial waste residues and low-grade building materials, delivering significant benefits in terms of comprehensive resource utilization and environmental protection.
5. High strength: The inorganic thermal insulation mortar system exhibits high bond strength with the substrate, preventing cracking and delamination. This represents a distinct technical advantage over all other thermal insulation materials available in China.
6. Excellent fire resistance and flame retardancy for peace of mind: The inorganic thermal insulation mortar system is non-combustible and highly fire-resistant. It is widely applicable to high-density residential buildings, public buildings, large public venues, flammable and explosive environments, and other locations with stringent fire safety requirements. It can also be used as a fire-isolation barrier during construction, thereby enhancing the overall fire-resistance standards of buildings.
7. Excellent thermal performance: Inorganic thermal insulation mortar-based insulation systems exhibit significantly superior heat-storage capacity compared with organic insulation materials, making them suitable for summer heat-shielding in southern climates. Moreover, their thermal conductivity can be reduced to below 0.07 W/m·K, and this thermal performance can be readily adjusted to meet both structural strength requirements and the specific functional needs of the application, allowing for versatile use in various settings such as floors and ceilings.
8. Excellent mold-prevention performance: It can prevent thermal bridging, thereby inhibiting the formation of mold stains caused by condensation inside the room.
9. Excellent cost-effectiveness: When an inorganic thermal insulation mortar system with an appropriately formulated composition is used to replace the conventional double-sided plastering method for both interior and exterior applications, it can achieve an optimal solution that balances technical performance with economic efficiency.
It is precisely because inorganic thermal insulation mortar boasts such superior performance that this relatively traditional type of insulation material is commonly used in the modern construction industry.
