Work manufactured in our workshop and installed in Hospitalet de Llobregat. Our client told us that he had noise problems and we offered this type of window with a specific glass against noise as well as excellent thermal efficiency. In the Ral 7022 color finish we made the two practicable doors with Channel 16 fittings, a type of fitting that offers more safety and handling than conventional fittings. Manufactured with the ALG 75 Máxima series, with the 6+6/27/4 + 4 Butylado Guardian Sun acoustic glass, this door is designed to reduce about 45 decibels of noise and also significantly reduce the bill in electrical costs , being highly efficient. With this door we get an acoustic attenuation of about 45 decibels, enough to reduce the most annoying noise. The customer was very satisfied once the installation of the doors was completed.
