Our Core and Best-Selling Product
The Polystyrene Thermal Insulation Board is our foundational product. It is also our best-seller. It is made from extruded polystyrene. The interior has a uniform closed-cell structure. This structure makes the thermal performance very stable. It does not degrade over time. It does not lose effectiveness when wet. It does not change shape with temperature shifts. Our Luckyfoam Polystyrene Thermal Insulation Board suits most building insulation needs. It works for new construction. It works for renovation projects. It works for residential buildings. It works for commercial buildings. It is always a reliable choice. We have been making XPS boards since 2003. We have 23 years of experience. We know this product inside and out. Our factory covers 15,000 square meters. We have three production lines. We use a 160-type extruder. We use a 150-type CO₂ foaming line. We use a 300-type CO₂ foaming line. Our monthly output is 50,000 cubic meters. Our annual output exceeds 300,000 cubic meters.
Specifications You Can Count On
The Polystyrene Thermal Insulation Board measures 1800 by 600 mm. The thickness ranges from 10 mm to 180 mm. The compressive strength is 200 kPa as standard. We can go up to 1000 kPa. The thermal conductivity is ≤0.034 W/(m·K). We can lower it to 0.024 W/(m·K). The water absorption rate is ≤1.5%. The dimensional stability is ≤1.5% after 48 hours at 70°C. The density is 25 to 32 kg/m³. We can customize it up to 65 kg/m³. The standard color is blue. We also offer yellow, pink, and white. We also contributed to the standard-setting for near-zero energy building insulation systems. This shows our technical expertise in the industry.
