Product Introduction

DDASAMI Board Rigid Polyurethane Foam

High-Efficiency Super Insulation Material

The rigid polyurethane insulation material stands out among organic insulation materials for its superior thermal conductivity, enabling application across various construction methods.
Additionally, it allows for a reduction in the thickness of walls and floors, facilitating the expansion of usable space.

Characteristics of DDASAMI Board

  • Thermal Insulation

    With its low thermal conductivity (0.020W/mk), this high-efficiency insulation material can be installed at 30-40% thinner than the thickness of Grade "A" insulation materials based on thermal transmittance, providing effective heat retention, cooling, and insulation.

  • Weather Resistance

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

  • Cost-Efficiency

    Its thinner construction compared to standard Grade "A" insulation thickness results in lower costs, thereby increasing indoor space.
    Additionally, its excellent insulation performance significantly reduces heating and cooling expenses.

  • Construction Efficiency

    The material has excellent adhesion and robust strength, reducing 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 blocks external and internal noise, contributing to a more comfortable environment.
