Polyurethane insulation characteristics
Polyurethane insulation meets two key elements of designing an effective insulation solution:
Low thermal conductivity
Durability
Advantages of polyurethane insulation
Reduce space loss
The limited space available for the placement of insulation materials is a common refurbishment problem. Polyurethane rigid foams have excellent low thermal conductivity, making them one of the thinnest and smallest footprint solutions.
Improve air tightness and eliminate cold bridges
Many older buildings have areas where insulation is weakened (thermal bridges), such as joints and doors and windows around the exterior walls of the building. These areas can cause air leaks. Cold bridges and air leaks can cause condensation. Filling these voids with one-component foam can easily solve this problem
Improve living comfort
Stable temperature control and air tightness can greatly enhance the comfort of life. Polyurethane rigid foam is one of the most effective insulation materials to achieve this goal: the effect of warm winter and cool summer can be achieved without increasing the cost of heating or cooling.
Provide solutions for difficult locations
Insulation of existing buildings sometimes requires the transformation of difficult to reach locations. Spray polyurethane foam provides a comprehensive solution that not only has good thermal insulation properties, but also bonds to any surface and cures quickly. Polyurethane infusion foam can be used for hollow and under-insulated hollow walls, which brings significant benefits in terms of energy saving, airtightness and structural properties, and properties and benefits of polyurethane foam insulation.
Low thermal conductivity
It is well known that polyurethane foams have excellent low thermal conductivity and are one of the materials with the lowest thermal conductivity in thermal insulation materials. This ensures that it retains heat efficiently, or, on the other hand, provides stable control of the temperature of the refrigerated or frozen environment.
Strength
Polyurethane rigid foams achieve high levels of shear and compressive strength. After bonding to a surface material such as metal or gypsum board, it is possible to increase the above strength.
Machinability
Polyurethane rigid foam is the only insulation material that can be processed in continuous fast or continuous batch production or through on-site mixing for spraying and filling operations.
Chemical resistance
Polyurethane rigid foams have excellent corrosion resistance and are resistant to many common chemicals, solvents and oils.
Fire performance
Like all organic building materials, polyurethane rigid foams are combustible materials, but can be calibrated for flammability and burn rate to suit a variety of architectural applications. Polyurethane insulation is usually protected by non-combustible or protective covering materials; the use of steel and other cladding materials can greatly improve the overall fire performance of the composite panel.
compatibility
Most of the building's cladding materials (including paper, fiberglass, aluminum, composite panels, gypsum board, asphalt and foil) are compatible with polyurethane rigid foam. The inherent strength of the foam can be increased in a variety of combinations to allow it to be used in semi-structures and cladding. It can also be coated with decorative surfaces such as face paint and plaster, so that the product can effectively exert moisture resistance in a high-humidity environment.
Adhesion
In the curing stage, polyurethane rigid foams are extremely strong and can be bonded to a variety of building facing materials. Adhesion often exceeds the tensile strength or shear strength of the foam.
Durability
Polyurethane insulation is not affected by water vapor or air permeation, does not sag or bulge, and is difficult to crush, which better ensures that it has high performance throughout the life of the building.
Water vapor permeation
Polyurethane rigid foams have a low water vapor permeability. Polyurethane foam products with aluminum foil or polyethylene film coverings will have water vapor permeability of these materials.
Lightweight
The typical density of polyurethane rigid foam is 30 kg/m 3 , at which time 97% of the volume of the body is the gas remaining in the void, while the polyurethane polymer only accounts for 3%. The light weight of the material is also a big advantage, which reduces transportation costs and ensures easier handling and installation on site.
