Polyurethane rigid foam waterproof and thermal insulation integrated board (referred to as 'integrated board') is a new type of building board that integrates functions such as waterproofing, thermal insulation, heat insulation, light weight, and high strength. Its core material is polyurethane rigid foam (PU), which is compounded with a waterproof layer and surface layer through a special process. With its excellent performance, this material is widely used in the following scenarios:
1. Building exterior wall insulation and waterproofing system
Residential and commercial building facades
Application scenario: As the core material of exterior wall insulation system, it is suitable for new buildings or energy-saving renovation of existing buildings.
Technical advantages:
High-efficiency thermal insulation: low thermal conductivity (≤0.024W/(m·K)), with a thickness of only 3-5cm to meet energy-saving standards, reducing wall thickness and increasing indoor use area.
Waterproof performance: The surface is compounded with waterproof membrane or coating (such as TPO, PVC, acrylic coating) to form a continuous waterproof layer to prevent rainwater penetration.
Integrated decoration: It can be combined with surface layers such as stone, aluminum plates, and real stone paint to achieve simultaneous construction of insulation and decoration, shortening the construction period.
Case: After adopting integrated panels in a residential project in a northern city, heating energy consumption in winter was reduced by 30%, and there was no leakage problem in the exterior wall.
Cold storage and constant temperature storage
Application scenario: Used for insulation of exterior walls, roofs and floors of cold storage to maintain internal low temperature environment.
Technical adaptation:
Low temperature stability: Polyurethane rigid foam has stable performance in the range of -180℃ to +120℃, avoiding cracking or deformation due to temperature changes.
Moisture-proof and anti-condensation: The waterproof layer prevents water vapor from penetrating, prevents condensation on the inner wall of the cold storage, and protects the safety of goods.
Case: After a large logistics cold storage adopts integrated panels, the energy consumption is reduced by 25%, and the internal temperature fluctuation is controlled within ±0.5°C.
2. Roof waterproofing and insulation project
Flat roof and pitched roof
Application scenarios: Suitable for roof waterproofing and thermal insulation of industrial plants, commercial complexes, public buildings, etc.
Technical advantages:
Lightweight and high strength: the density is only 30-50kg/m³, which reduces the roof load and reduces the structural cost.
Convenient construction: It is installed by mechanical fixing or bonding, without the need for on-site foaming, shortening the construction period.
Wind resistance: connected to the roof structure through special anchors, it can withstand strong winds above level 12.
Case: After using integrated panels on the roof of an airport terminal, the construction period was shortened by 40%, and it passed the wind-lifting test.
Metal roof repair
Application scenario: Used for thermal insulation and waterproof renovation of old metal roofs to solve corrosion and leakage problems.
Technical adaptation:
Flexible composite: An elastic sealing layer is set between the roof and the metal plate to adapt to the micro-deformation of the roof and prevent cracking.
Corrosion resistance: The waterproof layer uses weather-resistant materials (such as fluorocarbon coatings) to extend the service life of the roof.
Case: After the metal roof renovation of a chemical plant, the insulation effect increased by 50%, and there was no leakage repair record within 5 years.
3. Waterproofing and insulation of underground projects
Basements and underground garages
Application scenario: As a waterproof and thermal insulation layer for basement exterior walls, roofs and floors to prevent groundwater penetration and cold bridge effects.
Technical advantages:
Moisture-proof and mildew-proof: The closed-cell structure (porosity ≥95%) prevents water vapor from penetrating and prevents indoor moisture and mold growth.
High compressive strength: The compressive strength can reach more than 200kPa, adapting to the load requirements of underground engineering.
Case: After adopting integrated panels in an underground commercial complex, the indoor humidity was controlled below 60% and there was no condensation.
Tunnel and subway engineering
Application scenarios: Used for tunnel lining and subway station roof insulation and waterproofing.
Technical adaptation:
Strong durability: excellent UV resistance and anti-aging properties, with a lifespan of more than 50 years.
Fire protection performance: Flame retardants can be added to meet tunnel fire protection standards (such as B1 level).
Case: A certain city’s subway tunnel passed the fire protection inspection after adopting integrated panels, and there were no leakage problems during operation.
4. Cold chain logistics and industrial facilities
Cold chain logistics center
Application scenario: Used for the insulation layer of cold chain equipment such as cold storage, refrigerated trucks, and insulated boxes.
Technical advantages:
Efficient thermal insulation: small heat loss in low temperature environments, reducing cooling energy consumption.
Environmentally friendly and non-toxic: It uses environmentally friendly polyurethane raw materials and meets food contact safety standards.
Case: After a fresh food e-commerce cold chain center adopted integrated boards, the cargo loss rate was reduced by 15%.
Industrial pipe and equipment insulation
Application scenarios: Used for thermal insulation and antifreeze of steam pipes, hot water pipes, chemical equipment, etc.
Technical adaptation:
Customizable: Curved plates or special-shaped plates can be customized according to pipe diameter and temperature requirements.
Easy installation: adopts modular design, quick splicing and installation, reducing downtime.
Case: After adopting integrated plates for steam pipes in a chemical plant, heat loss was reduced by 40%, and the annual steam cost savings exceeded one million yuan.
5. Special environment and customized needs
Military and Defense Engineering
Application scenarios: Used for thermal insulation and waterproofing of military facilities, concealed projects, air raid shelters, etc.
Technical adaptation:
Impact resistance: Improve impact resistance through reinforced fiber or metal skeleton.
Concealability: Customized camouflage or low-reflective surface layers can meet military camouflage needs.
Case: After a border post adopts integrated panels, the indoor temperature in winter increases by 10°C, and the concealment is good.
agricultural facilities
Application scenarios: Used for thermal insulation and waterproofing in greenhouses, livestock and poultry houses, agricultural product storage warehouses, etc.
Technical advantages:
Controllable breathability: Achieve a balance between breathability and waterproofing by adjusting the surface material (such as non-woven fabric).
High cost-effectiveness: Compared with traditional insulation materials (such as foam board + waterproof membrane), the comprehensive cost is reduced by 20%.
Case: After using integrated panels in a vegetable planting base, the temperature in the greenhouse increased by 5°C in winter and the output increased by 30%.
