The evolution of civil construction increasingly involves the adoption of intelligent, high-performance, and sustainable materials. Among the technologies that have been gaining prominence, spray-applied PU has established itself as one of the most complete solutions for thermal insulation. Added to its properties is its high waterproofing capacity, especially useful when applied to roofs.
At Amino, we work with systems developed to perform well at sea level or at much higher altitudes, ensuring technical efficiency.
Why spray-applied PU is a standout solution in civil construction
The application of spray-applied PU has become a strategic choice in projects that seek thermal efficiency, continuous sealing, and durability. With direct application over substrates such as masonry, concrete, metal roofing, or fiber cement, PU forms a continuous layer that eliminates gaps and coverage failures, becoming an extremely efficient system.
Among the main benefits are:
- High-performance thermal insulation
- Effective sealing against moisture, wind, and infiltration
- Increased durability of roofs and façades
- Reduction of energy consumption and improvement of thermal comfort
- Fast, versatile application with less rework
This type of application is ideal for both new construction and retrofit of existing structures, optimizing thermal performance and extending the service life of the building.
Closed-Cell Foam
PU applied under this condition has closed cells, which is essential to obtain good thermal insulation, as well as other physical properties:
- High density, with a compact and sealed cellular structure
- Main indication: thermal insulation and external waterproofing
- Excellent barrier against water and vapor
- Ideal for roofs, slabs, and exposed external façades
Our technical team evaluates the context of the project, the substrates involved, and the client’s objectives to recommend the most appropriate system — always ensuring optimized performance and durability.rabilidade.
