Summary:This paper presents the design of a hot box with a cross sectional area of 3.5 m. x 3.5 m, to determine the heat transfer coefficient of windows and doors, under the ASTM 1363. For the design, the relevant standards were selected and defined specific atmospheric conditions to which it will be subjected in its useful life, evaluating as well the development of new materials. The test bench consists of three main sections: hot side, cold side and specimen holder. It has insulating walls with steel structure, which is provided with wheels for easy installation and assembly of different types of specimens as measuring instruments. In order to maintain stable air temperature and heat transfer coefficients, the sealed sections with rubber strips are maintained under pressure so that the heat flow or heat losses are minimal. Temperature was measured using thermocouples, where the location and tolerance of such instruments are based on ASTM C1363 standard. Additionally, drawings of equipment, system layout of data acquisition, processing cost estimate and schedule assembly were held.
