Sound Proof Windows

Secondary double glazing of windows & doors in Melbourne Australia. To secondary double glaze windows or doors means we install a new, fully independent secondary window or door on the room side of your existing window or door. Secondary glazing existing windows & doors is not only cheaper than double glazing, but provides better soundproofing. And, once manufactured, it only takes around one hour to install each secondary glazed window or door, so it is less disruptive than complete replacement. And we guarantee it will be draft proof.
