Recently, as increasing of demand for passive house and green house as low energy green building, development of lightweight insulation materials by using natural resource will be an important part for establishing green building technology in the future. Wood fiber insulation board (WFIB) can be a one of the key material for low energy consumption, comfortable, and safety construction of residential space because of its eco-friendly and high thermal insulation performance. This study was carried out to compare the characteristics of WFIBs manufactured with different conditions. WFIBs (20 mm (T), 0.10 g/cm3) were successfully manufactured by melamine-urea-formaldehyde (MUF), phenol-formaldehyde (PF), and emulsified MDI (eMDI), and latex resins. Thermal conductivities of all WFIBs were 0.037 W/m∙K which was similar insulation performance with extruded polystyrene foam. A 20, 25, 30, and 35% resin contents of melamine-urea-formaldehyde (MUF) was used for preparing of WFIB and then their properties were compared. There was almost no effect on the insulation performance of WFIBs. To investigate optimum density, WFIBs were prepared in 0.10, 0.15, 0.20 and 0.25 g/cm3. The higher thermal conductivity (0.037 W/m∙K) was observed on the WFIB at 0.15 g/cm3 density, and thermal conductivity tended to gradually increase to 0.043 ~ 0.046 W/m∙K as density increase. The optimum conditions of WFIB could be about 0.15 ~ 0.20 g/cm3 density with 25% resin contents of MUF for securing both insulation performance and human body and structural safety.
