Inorganic Granule Thermal Insulation Mortar

Inorganic granule thermal insulation mortar is a new type of energy-saving mortar material used for plastering both interior and exterior walls of buildings. It is primarily composed of inorganic lightweight insulation granules, cementitious materials, anti-cracking additives, and other fillers. Depending on the cementitious material used, inorganic granule thermal insulation mortar can be classified into two main categories: cement-based and gypsum-based.

Classification and Characteristics

Inorganic granule thermal insulation mortar mainly includes the following types:

Expanded Perlite Thermal Insulation Mortar: Features larger granules, higher water absorption, and higher thermal conductivity.

Vitrified Microsphere Thermal Insulation Mortar: Features smaller granules, minimal water absorption, lower thermal conductivity, better insulation performance, as well as fire resistance and protection against insect and ant erosion.

Performance and Applications

Inorganic granule thermal insulation mortar exhibits the following excellent properties:

Energy Efficiency and Waste Utilization: Made from inorganic materials, it is resistant to acids, alkalis, and corrosion, does not crack or peel, has high stability, and does not suffer from aging issues.

Thermal Insulation: Offers good thermal insulation performance, making it suitable for buildings in various climatic conditions.

Fire and Frost Resistance: Provides high fire resistance, as it does not burn, making it suitable for large public buildings.

Environmental Friendliness: Non-toxic, odorless, free of radioactive pollution, and harmless to both the environment and human health.

Ease of Construction: Can be directly applied to rough walls, with short construction time and low overall cost.

Wide Applicability: Suitable for various wall types and complex wall shapes, and can be used for both interior and exterior wall insulation, as well as roof insulation.

Market Applications and Prospects

Due to its excellent performance and low cost, inorganic granule thermal insulation mortar is highly favored in the market. Although expanded perlite thermal insulation mortar with cement as the cementitious agent was phased out in the past due to issues like high water absorption and easy pulverization, new types of inorganic insulation mortar, such as vitrified microsphere thermal insulation mortar, have gained widespread application due to their superior performance. Especially in regions with hot summers and cold winters, its thermal insulation properties can meet local energy efficiency requirements. It is easy to construct, has a high fire resistance rating, and offers relatively high cost-effectiveness.
