LiGrA Thermal Insulation Paint — Affordable Energy Savings Through Sustainable Coatings

Introduction

Keeping buildings cool in hot climates is expensive. Air-conditioning often accounts for 40–60% of household electricity bills in Southeast Asia. Thermal insulation paints provide a simple solution: they use special fillers that reflect sunlight and reduce heat transfer through roofs and walls.

Traditionally, these paints rely on ceramic microspheres, silica beads, or expanded perlite — all of which require high-energy processing or imports. LiGrA, processed into fine insulating powders through sintering, offers a low-cost, locally sourced, eco-friendly alternative. Its porous microstructure traps air pockets and enhances reflectivity, while also encapsulating heavy metals in industrial ash, ensuring no harmful leaching.

The Challenge with Conventional Thermal Paints

• High production energy for ceramic/perlite fillers.
  

• Imported materials raise costs and carbon footprint.
  

• Durability concerns: some fillers degrade under UV, humidity, or heat cycles.
  

• Limited affordability for low-cost housing projects.
  
  

The LiGrA Solution

• Porous filler: Traps air → lowers thermal conductivity.
  

• High reflectivity: Enhances solar reflectance when mixed with light pigments.
  

• UV and heat stable: Non-combustible, weather-resistant.
  

• Sustainable: Made from recycled waste streams with encapsulated heavy metals → safe and circular.
  
  

Hypothetical Project: Low-Cost Housing in Metro Manila

Scope: A government project retrofits 100 low-cost concrete homes with LiGrA thermal paint applied on roofs and exterior walls.

Paint Coverage:

• Roof area per house: 50 m²
  

• Wall area per house: 100 m²
  

• Total per house = 150 m²
  

• For 100 houses = 15,000 m²
  
  

1) Cost Comparison

• Conventional ceramic-based insulation paint: USD $2.50/m² × 15,000 = $37,500
  

• LiGrA-based insulation paint: USD $2.00/m² × 15,000 = $30,000
  

• Upfront saving = USD $7,500
  
  

2) Cooling Energy Savings

• Average indoor temperature drop: 5°C
  

• AC energy use cut: 20% reduction
  

• Average bill = USD $40/month/household
  

• Saving = $8/month × 12 months × 100 homes = USD $9,600 per year
  
  

3) Carbon Emissions Avoided

• Each house saves ~1,200 kWh/year (20% less cooling).
  

• For 100 houses = 120,000 kWh/year saved.
  

• Grid factor = 0.40 kg CO₂/kWh.
  

• Annual reduction = 48 tons CO₂
  
  

4) Waste & Safety Benefits

• 15,000 m² coating uses LiGrA powder equivalent to diverting ~20 tons of waste glass and ash.
  

• Heavy metals stabilized in sintered matrix — no leaching into rainwater or runoff.
  
  

Before vs After

👉 “With LiGrA thermal paint, one housing block saves $7,500 upfront, $9,600 every year in cooling bills, and cuts 48 tons of CO₂ — all while recycling 20 tons of waste.”

Conclusion

LiGrA thermal insulation paint is an accessible, high-impact solution for cooling buildings in tropical climates. By combining cost savings, durability, and sustainability, it delivers a triple win for governments, homeowners, and the environment. For communities, it means cooler homes and lower bills. For cities, it means lower carbon and smarter resource use.
