Timber Secondary Glazing for Sash Windows

The Sash Window Man is an approved installer of the SoundBlocker timber secondary glazing system. The SoundBlocker secondary glazing system is specifically designed for installation on timber sash windows where heat preservation and sound insulation is required but space to fit a conventional secondary glazing system is not available and when the way it looks is more important than the way it performs.

We have chosen to fit this secondary glazing system in preference to any other because it looks good, it is easy to use, it works well, and it can be painted to match the decoration of your existing windows, and thus appear almost invisible. Unlike most secondary glazing systems on the market it is made from wood, not plastic or metal.

Watch the video below to see how it works:
