Two Essential Functions in One Board
The Waterproof Thermal Insulation board combines two functions. It insulates. It also waterproofs. Many building parts need both. Basement exterior walls need both. Roof insulation layers need both. Ground floor suspended slabs need both. Using two separate materials costs more in labor and time. Our Luckyfoam Waterproof Thermal Insulation solves both with one board. The XPS material has a very high closed-cell rate. Moisture cannot get through. Waterproofing is excellent. Its thermal conductivity is very low. Thermal insulation is excellent. One board. Two uses. One less step in construction. One less cost. We have been making XPS since 2003. We are one of the earliest XPS manufacturers in Southern Zhejiang. Our factory covers 15,000 square meters. We have three production lines. We produce 50,000 cubic meters per month. Our annual output exceeds 300,000 cubic meters.
Proven Performance in Underground and Roof Projects
The Waterproof Thermal Insulation measures 1800 by 600 mm. We also support large board sizes up to 2440 by 1220 mm. The thickness ranges from 10 mm to 180 mm. The compressive strength is 200 kPa. 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 have supplied this board to Sanmen Nuclear Power Plant and Fuding Nuclear Power Plant. Underground structures there needed both insulation and waterproofing. Our Waterproof Thermal Insulation met the requirements.
A Smart Solution for Below-Grade and Roof Projects
The Waterproof Thermal Insulation is widely used in underground projects. Large commercial buildings use our board on basement exterior walls. The soil outside is wet. Groundwater is present. The board keeps the basement warm. It also keeps groundwater out. Roof garden projects also use our board. Plants and soil are on top. Living space is below. Waterproofing and insulation are both critical. Our product does both jobs well. We offer a one-year warranty. We support mixed orders. We support OEM. We support EXW, FOB, and DDP terms. We accept RMB and USD payments.
