PURPOSE: An insulation material construction method using liquid type polyurethane is provided to enhance the thermal insulation efficiency by completely blocking a gap between insulation materials with liquid type polyurethane. CONSTITUTION: An insulation material construction method using liquid type polyurethane is as follows. Foreign materials and moisture on a wall are removed and positions for fixing spacer pins are marked(S1'). The spacer pins are fixed at a predetermined interval on the wall where thermal insulation is needed(S1). Liquid type polyurethane is sprayed on a surface of the wall where the spacer pins are fixed(S2). Covers are fixed on the spacer pins(S3). An interior finishing material is attached on a side of the covers(S4). |
