“…Their research results showed that the values of both studied thermo-physical characteristics fulfilled the requirement laid for the thermal insulation. It means the recycled textile materials have competitive thermal properties and can be used as an alternative to commercial thermal insulation materials (the extruded polystyrene or mineral wool) in construction [9].…”

The sound absorption coefficient is a commonly used parameter to characterize the acoustic properties of materials. The fire performance of construction products has to be evaluated on the basis of their reaction to fire performance. The evaluation of the reaction to fire performance for the flammable construction materials which are in Class E reaction to fire is based on the ignitability test and the thermal test using the radiant heat source. For this study, nine types of STERED® products, which were made from the recycled automotive technical textiles, were chosen in order to evaluate their ability for sound absorption and the reaction to fire. The fire performance was evaluated on the basis of the relative mass loss in the radiant heat source test; the ignitability in accordance with ISO 11925-2, the possible appearance of flame, duration of flame, and the glowing during the single flame source test. The sound absorption of nine products was rated on the basis of the sound absorption coefficient and the noise reduction coefficient. The measurement was performed using the transfer function method in accordance with ISO 10534-2. From the nine tested types of STERED® products, the product Senizol AT XX2 TL 60 had the lowest mass loss at thermal loads up to 700 °C and it fulfilled the conditions for Class E reaction to fire. This product had the highest noise reduction coefficient of 0.81 and a high absorption coefficient for frequencies ranging between 500 Hz and 2000 Hz. The STERED® product Senizol AT XX2 TL 60, as well as Senizol AT 22 TL 50, Senizol AT 40 TL 25, Senizol AT XX4 TL 50 and Senizol AT XX4 TL 10 with a sound absorption coefficient α of between 0.80 to 0.95 and corresponding NRCs from 0.66 to 0.81, these STERED® products can be classified according to ISO 11654 into the sound absorption classes A and B.

101|Medición de la conductividad térmica en materiales aislantes bajo régimen de flujo de calor no estacionario construcción, el tamaño de las muestras a evaluar y el método de medida, comparado con los métodos tradicionales para medir este parámetro.Palabras clave: Conductividad térmica; flujo de calor; aislantes térmicos; incertidumbre; consumo energético; construcción de edificaciones. AbstractA device to measure thermal conductivity in thermal insulating solid materials commonly used in buildings was developed following a one-dimensional model of heat flow through a plate of the material to be evaluated. The temperature gradient between the plate faces was measured as a function of time by means of a set of type T thermocouples. A circuit with commercial microcontrollers was designed to control the instrument's mechanisms, the acquisition and the treatment of data. In preliminary tests with some materials, thermal conductivity values similar to those reported in the literature were obtained by using a linear adjustment with R values between 0.90 and 0.98. This device turns out to be a good instrument for measuring thermal conductivity because it has several advantages, such as: easy implementation, sample size, measurement method; compared to those using traditional methods.
