Project shelter, Part 1: Fire resistance and thermal insulation

Abstract

In Chile there is a gap that needs to be filled in order to have a positive impact upon emergencies, particularly in emergency houses (EH) In this study were evaluated the properties of a prefabricated prototype based on a "Structural Insulated Panel" 64mm thick (SIP64), built by two OSB panels bonded with a two component polyurethane adhesive to a high density expanded polystyrene core. SIP64 was manufactured as a main element for construction of EH. The thermal insulation was evaluated by NCh 853:2007 and was equal to 1.41 [m*K/W] equivalent to a thermal transmittance to 0.71 [W/m*K]. In fire resistance (FR), the quality was determined by NCh 935/1.Of97. The FR was F15 class, minimum safety requirement for bearing vertical elements and non-supportive frame walls. It is feasible to use the SIP64 as the main element in the construction of EH. FONDEF D09I1058 project has developed Technical and Normative standards for wood shelter. As main products Manuals for Manufacturing, Installation, Technical Specifications and Regulations for EH were developed and are available online for free.
