DDASAMI Board Rigid Polyurethane Foam

High-Efficiency Super Insulation Material

The rigid polyurethane insulation material is among the organic insulation materials with the best thermal conductivity performance,
allowing for its application in various construction methods. Moreover, it reduces the thickness of walls and floors, facilitating the creation of more spacious areas.

Characteristics of DDASAMI Board

  • Thermal Insulation Properties

    With its low thermal conductivity (0.020W/mk), this high-efficiency insulation material allows for construction at 30-40% thinner than Grade "A" insulation materials based on thermal transmittance criteria, enabling thinner applications while maintaining excellent thermal insulation.

  • Weather Resistance

    The product does not deform due to external heat and maintains its physicochemical properties without changes.

  • Cost-Efficiency

    Since it can be applied thinner than the typical Grade "A" insulation thickness, it is more cost-effective and allows for the expansion of interior space.
    Additionally, its superior insulation performance continuously reduces heating and cooling expenses.

  • Construction Efficiency

    The board has excellent adhesion properties and robust strength, minimizing the risk of damage during transport and allowing for various construction methods.

  • Waterproofing and Durability

    With excellent mechanical strength and moisture resistance, it prevents condensation on walls and deterioration of insulation performance.

  • Sound Insulation

    Its superior sound insulation performance blocks noise from inside and outside the building, creating a more comfortable space.

  • a Density is optional in a country that has established a system of class identification.

  • b A specific limiting value (maximum or minimum, depending on the application) may be selected by agreement between purchaser and supplier.

  • c Flame retardancy shall comply with applicable national laws and regulations, including the Building Act, to protect life and property by preventing the generation of toxic gases and the spread of fire within the building. Flame retardancy is an optional quality requirement that applies only within the scope of application specified by national laws and regulations, according to the building's use and scale. Where applicable, the material shall meet the performance criteria for semi-noncombustible materials and flame-retardant materials specified in the relevant laws and regulations.

  • d Water absorption is required when direct contact with water is expected in end-use applications, such as inverted roof insulation, or similar applications.

  • e These may be determined separately by agreement between purchaser and supplier.
