Advantages of wall insulation spraying
Enhanced Thermal Insulation Performance, Improving Energy Efficiency By 30-50%
High closed-cell rate and low thermal conductivity allow for a single spray application to form a highly efficient insulation layer.
Seamless And Waterproof, Waterproofing And Insulation Achieved In One Step
The sprayed polyurethane adheres perfectly to the roof structure, without seams, nail holes, or joints, eliminating concerns about leaks in rain or snow.
Lifespan Can Reach 20–30 Years, With Low Maintenance Costs.
It is weather-resistant, water-resistant, and aging-resistant, not prone to cracking, and does not require frequent repairs or replacements.
Strong Adhesion, No Delamination Or Hollow Spots
Whether on concrete roofs, corrugated steel roofs, or for old roof renovations, the sprayed coating adheres firmly and offers strong wind resistance.
Insulation And Sound Insulation
The microporous structure of polyurethane effectively reduces roof noise (rain/wind noise) while also providing insulation.
Fast Application Speed
The spraying machine can achieve a flow rate of 2-12 kg/min and can be equipped with 60-105m heating pipes, making it far more efficient than panel or roll-type applications.
Recommended Thickness Of Wall Insulation Layer
Roof Type / Climate Conditions | Recommended insulation thickness | Description |
Tropical/Warm Regions (Hot Year-Round) | 3–5 cm | Primarily reduces direct sunlight heat and improves cooling efficiency. |
Conventional Residential Roofs (Four Distinct Seasons) | 5–8 cm | Most commonly used thickness for residential roofs, with significant energy-saving effects. |
Cold Region Roofs (Long Winters) | 8–12 cm | Improves thermal insulation performance and reduces heat loss in winter. |
Industrial Plants/Steel Structure Roofs | 5–10 cm | Insulation + noise reduction, improving the indoor environment. |
Warehouses/Logistics Buildings (Requires Temperature Control) | 8–12 cm | Upgrades insulation level and stabilizes indoor temperature. |
Cold Storage Roofs (0℃–5℃) | 10–15 cm | For high insulation requirements, reduces cold loss. |
Frozen Storage Roofs (Around -20℃) | 15–20 cm | Thicker coating is necessary in extremely cold environments, using multi-layer spraying. |

- Our polyurethane tank insulation spray coating uses a high closed-cell formula with a closed-cell rate of over 90% and a thermal conductivity as low as 0.022 W/(m·K). This allows it to quickly form a dense, seamless insulation layer on the tank surface, significantly reducing heat loss.
- The material has a controllable expansion ratio and strong adhesion (≥ 0.3 MPa), maintaining uniform foaming on vertical, horizontal, and large curved tank surfaces without sagging or collapsing.
- The material has a temperature resistance range of -40℃ to 120℃, is resistant to aging, waterproof, and corrosion-resistant, and maintains stable insulation performance even after long-term use.
- We also offer customized formulas to better suit customer temperature requirements, construction environments, and tank types, resulting in more efficient and durable insulation.

PU Spray foam machine roofing insulation Success Stories
A Russian commercial building owner used our high-performance polyurethane spray coating material in a roof insulation renovation project. Due to the complex roof structure, traditional insulation materials were difficult to apply and prone to leakage. We provided a customized formula with a controllable expansion ratio and high closed-cell rate, along with full technical support. The application was completed in just two days, forming a dense insulation layer with a thermal conductivity as low as 0.022 W/(m·K), significantly reducing energy consumption. The owner reported that the roof’s waterproofing and insulation performance far exceeded expectations, while the construction period and labor costs were significantly reduced, resulting in a noticeable overall energy saving for the project.
▶ Watch on YouTubeThe equipment performed very stably, with uniform pressure output and precise foam mixing. Even in cold environments, there were no issues with nozzle clogging or pressure fluctuations. The team was also very professional in installation and training, allowing us to quickly get started. We are very satisfied with this sprayer and will continue to use it and recommend it to our peers.
