The purpose of this study was to find solutions for unlocking the production of wool from sheep as an alternative to the use of insulation materials and traditional isolation to improve comfort index, which lead to decrease heat loss in winter, to reduce intake summer heat and provide a positive thermal balance inside the building. The research was conducted by the method of comparing the existing data in the literature on the technical features of main construction materials used for thermal insulation and construction noise. It also was a cost analysis and thermal insulation per unit area. Following the study observed that the coefficient of thermal conductivity value for wool sheep (λ), is 0.0326 kcal / m · h · ° C, slightly higher than that of expanded polystyrene which has a value of 0.029 kcal / m · h · ° C and lower than for mineral wool that has a value of 0.060 kcal / m · h · ° C. Given the qualities of good isolation system of sheep's wool, it can be concluded that its use in construction may be one of the main options for recovery, given that national production of wool is purchased in a proportion rather reduced from producers.
