04. Semi-Noncombustible Polyurethane Foam
The building insulation material is made of polyisocyanurate (PIR) known for having the lowest thermal conductivity among all insulation materials. It is a top-grade insulation material that satisfies the heat transmission rate at half the thickness specified in the energy saving design standard.
Thermal InsulationIt has the lowest thermal conductivity among insulation materials, and it completely blocks heat conduction even with a low thickness, which helps maximize spatial utility.
Flame Retardant & Heat ResistantPIR is a semi-noncombustible polymer building material that displays excellent flame-retardant properties compared to other insulation materials. It satisfies KS M 3809, which requires heat resistance at temperatures up to 100°C.
Sound InsulationPolyurethane foam makes an excellent sound insulation material that blocks noise transmission from both the inside and outside. So those indoors can enjoy peace and quiet, regardless of what is going on outside.
EconomicalIt produces a relatively low amount of industrial waste, and it boasts excellent workability. Thus, it reduces the time and cost it takes to complete the insulation installation work compared to other materials.
Moisture-proofWhen moisture penetrates into an insulation material, its performance decreases by 30 to 50%, so it is necessary to install a moisture-proof layer on the walls and floors to prevent this. Polyurethane uses a vapor barrier and PE coated paper as a surface material, so there is no need to make a separate moisture-proof layer.
■ Semi-Noncombustible Urethane Board
The isocyanate ring structure ensures excellent safety against fire and prevents deformation. It does not melt even when combusted, and this helps minimize the chance of a fire spreading. It also displays excellence when it comes to toxic gas emissions and gas hazards.
■ Urethane Board
It has recorded the lowest thermal conductivity (0.020 W/m·k) and the best thermal insulation performance among thermal insulation materials for buildings. A PIR board is a building material that helps save energy and promotes fire safety, based on excellent flame-retardant performance to lower the chance of combustion.
