Window installed on Barcelona’s Meridiana Avenue. This study sought to isolate noise from the street rather busy, so it installed a white lacquered aluminum window practicable type of two sheets of the Stilo-50 series, which offers a money quite competitive in the market. The peculiarity of this window is a glass incorporating acoustic butylated 4-10-3+3, ie a glass of 4 mm in the interior, an air chamber of 10 mm and a laminated glass 3 +3 mm, the inner sheet is specifically designed to isolate the noise. Depending on the glass thickness acoustic noise we isolate a greater or lesser extent. In windows incorporating blind, is somewhat more complex noise reduction, since no longer a resonance box which we magnified the noise inside the house. To avoid as much noise input by the registration of the blind, we developed a special cover with a material of higher density to achieve our goal. It is recommended, in case you have blinds, installing an electric motor for driving the same, because with this system, we will avoid the noise and air inlet by passing tape. As we see in the two pictures below, were reduced from 30-35 decibels, which now allows the client to rest quietly at night in your home. We recommend this type of glass in the busiest streets in the case of Barcelona and the Gran Via street, Avenida Diagonal, Travessera de Dalt, Rounds … etc.. Installation time was three hours of two workers. In case you need more information or have any questions, please contact us, we will respond without any compromise.
