Product Introduction
Rigid Polyurethane
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.
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.
The product does not undergo deformation due to external heat and maintains its physicochemical properties without changes.
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.
The material has excellent adhesion and robust strength, reducing the risk of damage during transport and allowing for various construction methods.
With excellent mechanical strength and moisture resistance, it prevents condensation on walls and deterioration of insulation performance.
Its superior sound insulation blocks external and internal noise, contributing to a more comfortable environment.

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.
