SJB Silver Range UPVC Windows London

SJB Silver Range UPVC sash Windows are a prestigious market-leading sash window that embodies period charm and character in every aspect. Manufactured with traditional detailing found in original period windows, the SJB Silver Range comes highly customisable and in a range of colours to suit your requirements. Decorative features such as authentic astragal bars and run-through sash horns ensure authenticity and make these windows virtually indistinguishable from timber originals.

These highly engineered windows are both secure and perform, especially when looking at acoustic and energy efficient levels. Furthermore, the modern technology behind these SJB Silver Range windows means that they are low maintenance and easy to operate.

SJB Silver Range windows also boast the slimmest sightlines available. They have flat putty-style external glass lines together with subtly moulded internal ones, fully matched on the astragal bars. There are also triple-sealed concealed brush piles, discreet silver or black gaskets and an authentic deep bottom rail.
The SJB Silver Range window also features a bespoke run-through horn, which is topped off with a flush fitting cap, the result of which is the most authentic run-through horn we believe you will find.

Another SJB Silver Range innovation sees both sashes tilt inwards, making them easy to clean from within your home. These windows might have been designed with authenticity in mind first, but they have modern benefits without affecting cost.

Max width/height and energy rating are dependent on finish and glazing configuration.
