It is said that the standard of the education is down to the teacher’s skills and somewhat of the individual; others will place more emphasis on the resources of the school. But what about the building itself? The sound of commuter traffic from the outside drifts in, voices in the hallway can be heard as people walk to class, a draft from the windows sweep in - not a comfortable environment to learn in, let alone to concentrate. Secondary glazing can help combat all of these problems and can also improve a building’s energy efficiency and increase window security.
