Building Wall Thermal Insulation Coating
Thermal-management materials for equipment, pipework and building assemblies where heat-transfer control is required.
Product overview
Thermal-management materials for equipment, pipework and building assemblies where heat-transfer control is required.
A building insulation coating designed around hollow glass microspheres and a water-based binder system for lower-density wall insulation layers.
Problems addressed
Heat transfer through building wallsHeavy conventional wall insulation build-upsWall renovation requiring a coating-based approach
Selection guidance
How this system differs
This series manages heat transfer; it does not replace a structural repair, leak repair or corrosion-control system where those problems are active.
What must be confirmed
Suitability depends on the actual substrate, medium, concentration, temperature cycle, exposure mode and application window. Final system selection and project-specific instructions require technical review.
Product features and advantages
Low density
Low thermal conductivity
Single-component application
Applicable to prepared concrete, render and compatible metal surfaces

Project application guidance
Confirm substrate condition, contamination, corrosion, defects and access before work starts.
Remove oil, dust and loose material; prepare cleanliness and profile to the reviewed product procedure.
Check compatibility of retained coatings and complete a representative trial area when the existing system is uncertain.
Prepare and mix only according to the product source; do not improvise ratio, thinner or pot life.
Build a continuous system in controlled layers, with special attention to edges, welds, joints and shadow zones.
Protect the applied area through curing, then inspect continuity, visible defects and recorded source-backed acceptance items.
Source-specific procedure
Surface Preparation
Concrete/render must be sound, dry and clean; new cementitious surfaces require curing, moisture <10% and pH <10.
Application Environment
Normally ≥10°C; substrate ≥3°C above dew point; relative humidity ≤85%; stop below 5°C.
Mixing
Stir the single-component paste until uniform.
Application Tools
Trowel, scraper or airless spray.
Thickness per Coat
Build 2-3 mm in multiple coats; do not apply too thickly in one pass.
Curing
At least 72 h before decorative finish coating.
Packaging, storage and transport
Packaging15 kg/pail
StorageDry, cool, clean interior; protect from freezing and sunlight; 5-40°C
Shelf Life12 months unopened
TransportMaintain 5-40°C

Quality checks
Check surface-preparation records, environmental conditions, layer continuity, edges, welds and visible defects. Use only acceptance criteria stated in the reviewed product or project documents.
Maintenance and repair
Inspect representative high-risk locations during planned maintenance. Clean the area, identify the cause of damage, feather sound edges and verify compatibility before local repair.
Scope and limitations
Suitability depends on the actual substrate, medium, concentration, temperature cycle, exposure mode and application window. Final system selection and project-specific instructions require technical review.
