Abstract
This article provides an evaluation of the acoustical and thermal performance
of some closing systems by referencing materials such as cement plates, plasterboard
walls, precast concrete panels and expanded polystyrene. Reverberation time is calculated
by applying an empirical formula, which uses temperature and relative air
humidity values obtained from simulations that were conducted using the computational
simulation program ESP-r (Energy Simulation Program-research). The internal
temperature presented by the ESP-r is an indicator of thermal performance. Using a
simplified graphic method, the acoustical performance is also evaluated by estimating
the loss of sound transmission that occurs through the closing panels. Combinations of
these panels, which form multilayer panels mediated by a layer of air and with or without
insulating material between them, are applied. The results show that multilayered
closing systems, when filled with insulating material, are an efficient solution than can
provide adequate acoustical and thermal performance.
