What thermal performance can I expect?

Thermal conductivity is about 0.06-0.10 W/(m*K) , delivered by closed-cell vitrified microsphere aggregate - comparable to thin insulation boards while also providing leveling.

What is the mixing (water-to-powder) ratio?

Typical ratio by weight is 100 parts powder : 45-55 parts clean water). Add powder to water, mix 3-5 min, rest 2-3 min, remix, then apply within the open time. Do not re-temper after setting.

Yes. It is an inherently non-combustible inorganic mineral system with A1-class fire rating, suitable for exterior facade fire-safety compliance.

Key features

Insulation & Leveling in One: Combines thermal insulation and base-leveling in a single coat, replacing the separate insulation board + plaster workflow.

Lightweight & Load-Reducing: About 50% lighter than cement mortar, cutting wall dead load -ideal for renovation and high-rise.

A1-Class Fireproof: Inherently non-combustible inorganic mineral system, safe for fire-code compliance on exterior facades.

Low Thermal Conductivity: Closed-cell vitrified microsphere aggregate delivers 0.06-0.10 W/(m*K), comparable to thin insulation boards.

Energy-Saving Envelope: Raises wall thermal resistance, cuts heating/cooling energy use in new and retrofit buildings.

Crack-Resistant: Microsphere elasticity and controlled shrinkage resist cracking under thermal movement.

Breathable & Anti-Condensation: Vapor-permeable structure prevents internal condensation and mold.

Single Component, Just Add Water: Factory pre-blended, ready to mix on site - no on-site dosing errors.

Interior & Exterior Use: Suitable for both indoor and outdoor wall insulation-leveling systems.

Eco-Friendly Inorganic: Mineral-based, low VOC, recyclable -safe and sustainable building material.

AI-Powered supplier vetting

SummaryShanghai Languan New Building Materials Co., Ltd. is described as a developer, manufacturer, and seller of environmentally friendly building decoration materials. Its stated scope covers building materials, floor-related solutions, machinery and equipment, hardware, chemical products, communication equipment, and import/export and technical services. The supplier reports OEM service for well-known brands, quality assurance, documented complaint-handling and corrective-action procedures, and facilities including mixing, self-leveling, and automatic packaging lines. However, it has no available SDK, no stated AI-based decision-management practice, no inventory capability, no overseas warehouse or showroom, and no valid manufacturing-capacity contract with affiliated subcontractors. Financial information is limited to years identified as 2021–2023 without performance values. Certification, customer cases, and detailed customization evidence are not sufficiently documented.

Supplier typeThe supplier is presented as Shanghai Languan New Building Materials Co., Ltd., focused on R&D, production, and sales of environmentally friendly building decoration materials. Its business scope includes building materials, insulation materials, sealing fillers, cement products, machinery, hardware, chemical products, and related sales and import/export activities, supporting classification as a building-material manufacturer and supplier.

After-Sales capabilityThe supplier reports clear procedures and records for corrective and preventive actions and customer complaint handling, and describes providing technical guidance and comprehensive customer services. However, it lacks overseas warehouse and showroom capabilities, so the evidence supports structured service handling but not broad overseas after-sales infrastructure.

R&D capabilityThe company describes R&D activity and the ability to develop new materials using existing technology, and its culture emphasizes innovation. However, it explicitly has no available SDK and has not established an AI model for big-data decision support; these limitations prevent a broad conclusion that its innovation capability exceeds requirements.

Production capacityThe supplier states that it conducts production and lists processing and manufacturing activities, with a mixing line, self-leveling production line, and automatic packaging robot. Quality assurance and documented corrective-action procedures are also reported, although there is no valid contract with affiliated subcontractors and no in-stock capability.

Customization capabilityThe supplier reports OEM services for well-known brands and says it provides solutions for difficult floors, technical guidance, and development of various new materials using existing technology. This directly supports some customization and OEM capability, although the slices do not specify product scope, minimum quantities, lead times, or engineering resources.

Product Q&A

Q:What is this product used for?

It is a single-component inorganic thermal insulation plaster for interior and exterior wall insulation and base-leveling. One coat simultaneously insulates and levels the wall -an efficient replacement for the separate insulation-board + plaster workflow.

Q:What thickness can be applied in one coat?

Recommended single-coat thickness is 10-50 mm. Use 10-20 mm for thin leveling, 20-30 mm for standard insulation-leveling, and up to 50 mm for heavy-duty thermal upgrade (may be done in one or two layers depending on substrate and spec).

Q:Do I need a primer before application?

On highly absorbent substrates (AAC blocks, porous brick) dampen first; on very smooth or low-suction concrete, apply a bonding primer/interface agent (e.g. LG660 / LG690) to ensure adhesion. Normal masonry generally needs no primer.

Q:Can it be used on exterior walls?

Yes. It is designed for both interior and exterior wall insulation-leveling systems. For exterior use, finish with an approved anti-crack reinforced protection layer and decorative render per local energy-code design.

Q:How does it compare with EPS / XPS insulation boards?

It forms a seamless, monolithic layer without cold bridges, is vapor-permeable (anti-condensation) and A1 fireproof. Boards often need separate fire rating and create joints/cold bridges. Plaster also saves the extra plastering step.
