Double Glazing Specialist

Installing a secondary retro-fit acoustic window or door will provide significant noise reduction to your home, office or commercial application. Traditional double glazing, or refitting thicker glass, will not give you the same level of noise reduction as a secondary system.  Science explains why - it is all about the air gap! Without an air gap, optimally 100mm overall, noise cannot effectively be broken down and reduced.
