Inorganic Thermal Insulation Mortar for Interior Walls

Inorganic thermal insulation mortar for interior walls is a new type of energy-saving mortar material used for plastering both interior and exterior walls of buildings. It offers excellent properties such as energy efficiency, waste utilization, thermal insulation, fire and frost resistance, and aging resistance. It is also low-cost and has a broad market demand.

Composition and Properties

Inorganic thermal insulation mortar for interior walls is primarily composed of inorganic lightweight insulation particles (such as fly ash floating beads, glass floating beads, ordinary expanded perlite, polystyrene particles, and vitrified microspheres) as lightweight aggregates, combined with cementitious materials, anti-cracking additives, and other fillers to form a dry-mix mortar. When mixed with water, it forms a slurry that is applied to the base surface and hardens to create an insulation layer. This material has the following characteristics:

Strong temperature and chemical stability: Made from pure 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, matching the lifespan of the building walls.

Simple construction: It can be directly applied to rough walls, with a construction method similar to that of cement mortar leveling layers. The machinery and tools required are simple, the construction period is short, and quality is easy to control.

Wide applicability: Suitable for various wall base materials and complex wall shapes, it is fully sealed, seamless, and cavity-free, preventing thermal bridging.

Environmentally friendly: Non-toxic, odorless, and free of radioactive pollution, it is harmless to the environment and human health. It also utilizes some industrial waste and low-grade building materials, offering significant environmental benefits.

Application Scenarios

Inorganic thermal insulation mortar for interior walls is suitable for various wall base materials and complex wall shapes, including external wall insulation, internal wall insulation, simultaneous internal and external wall insulation, as well as roof insulation and underfloor heating insulation layers. Its fully sealed, seamless, and cavity-free design effectively prevents thermal bridging.
