Thermal and acoustic insulation samples were prepared from white Portland cement. The paste of recycled paper and water was suitable to form secondary roofs, walls, and use as a non-traditional construction materials. The paste made by (paper: water) with different weight ratios) 4:1( )2:1) )1:1). These samples were reinforced by hemp as a natural fibers with weight ratios (10% and 30%), both Physical, thermal, and acoustic insulation properties was studied for the insulation samples. There results reveal decreasing thermal conductivity and increasing acoustic insulation. When the paste (paper: water) at ratio (1:1). At last, the addition of Hemp fibers at ratio (30%) to insulation samples effect on some properties, Thermal conductivity decrease to (0.2W/Mk). While the acoustic insulation increase when the acoustic level decrease to (90dB), bending and diametrical strengths increase with this addition, Finally these composites materials have a combustion resistance, no emitted toxic gas led this material can be an eco-friendly materials.
