In this study we evaluated the properties of a prefabricated HOUSING prototype based on a 64mm thick "Structural Insulated Panel" (SIP; hereinafter SIP64), built by two OSB panels bonded with a two component polyurethane adhesive to a high density expanded polystyrene core. This panel was manufactured as a main element for walls in the construction of emergency housing. The thermal insulation of the SIP64 panel was evaluated according to NCh853Of.91 (thermal insulation standard to calculate the thermal resistance and transmittance). The thermal requirements for exterior walls, Roof an ventilated floors in Chile are dictated by the General Urbanism and Construction Code (OGUC) for 7 climatic zones, so we could secure in which zone it was possible to use de SIP64 panel on exterior walls. Analytical calculation is obtained from the thermal resistance of the SIP64 panel was equal to 1.41 [m * K / W] equivalent to a thermal transmittance of 0.71 [W / m * K], therefore the SIP64 panel matches the thermal requirements in all climatic zones except zone VII. In terms of fire resistance, the quality of SIP64 panel was determined empirically to withstand a common fire under NCh 935/1.Of97 standard test. In this case, it is also the Chilean General Urbanism and Construction Code that dictates the fire resistance requirement for vertical bearing elements. The fire resistance of the panel corresponds to the F15 class, which meets the minimum safety requirements for bearing vertical elements and non- supportive frame walls. Ultimately, it was concluded that it is feasible to use the SIP64 panel as the main element in the construction of emergency housing, meeting the minimum requirements of habitability and safety, and safeguarding the technical design and construction requirements dictated by the OGUC form permanent housing. The SIP64 panel proved also to below cost and easily built, which is also e main interest in emergency housing.
