Abstract: This research focused on the preparation of insulation sheets from oil palm fibers (OPF) and waste rubber foam (WRF) blended with natural rubber latex (NRL) to enhance the properties for building materials. These materials were investigated for flammability, thermal conductivity, sound absorption, and mechanical properties. In the case of flammability of the materials, it was found that the best condition for fire resistant materials was the treated OPF and WRF with 10% (w/v) borax that were blended with the diluted rubber compound (DRC): water (weight ratio of 1:3) and 16%wt zinc borate. The insulation sheets with various ratios of treated OPF, DRC, and treated WRF (1:3:0, 1:3:0.2, 1:3:0.4, 1:3:0.8, 1:3:1.2 weight ratios, respectively) were studied. The results showed that the insulation sheets with the treated OPF, DRC, and treated WRF (1:3:0, 1:3:0.2, and 1:3:0.4 weight ratios) did not ignite. After that, the effects of the amount of treated WRF on the thermal conductivity and sound absorption were investigated. It was found that the increase in the amount of treated WRF led to the better thermal and sound insulation properties. The insulation sheet with the treated OPF, DRC, and treated WRF (1:3:1.2 weight ratio) had the best values of thermal conductivity and noise reduction coefficient (NRC) were 0.0036 W/m.K and 0.293, respectively. Moreover, the bending strength, internal bonding, and thickness swelling of the insulation sheet with the treated OPF, DRC, and treated WRF (1:3:1.2 weight ratio) showed the best values that were 0.4197 MPa, 0.1337 MPa, and 0.9394%, respectively. The results indicated that the treated OPF and WRF enhanced the mechanical properties of the insulation sheets. However, the optimum ratio of insulation sheet with the treated OPF, DRC, and treated WRF for building applications was 1:3:0.4 weight ratio because this insulation sheet did not ignite, used more waste rubber foam, and displayed the good properties such as fire resistance, thermal insulation, sound insulation, and mechanical properties.
