Vertical sliding secondary glazing units from Granada Glazing are an elegant choice to solve problems with noise intrusion, heat loss, condensation and poor security in heritage and modern properties alike.
Designed specifically for traditional box sash windows, our vertical sliding secondary glazing blends in seamlessly with the internal décor and are undetectable from the outside, maintaining the character of a building’s external appearance.
This makes them perfect for listed, heritage and conservation area properties where planning regulations do not allow the installation of modern double glazing. Vertical sliding secondary glazing is also an option where regular hinged panels are not suitable.
The vertical sliding secondary glazing range features three variations, all of which are designed with a traditional look, yet deliver 21st century standards of comfort. They offer a cost-effective and efficient solution in reducing external noise by up to 80% and improving thermal insulation by up to 65%.
Vertical sliding secondary glazing units can be installed either face-fixed or reveal-fixed on the inside of primary windows. They are also lockable and provide additional security, especially for single-glazed box sash windows.
Our Balanced Vertical Slider is a traditional vertical sliding product and works just like a traditional box sash. The vertical sliding units use two sashes, one above the other, retained within an outer frame. Durable spring balances support the units for easy movement, while brass rollers provide a smooth sliding action.
The Tilt-In Vertical Slider adds a convenient tilt-in feature that allows each secondary unit to be independently released from the outer frame. This variation has restrictor arms as standard which, once removed, allows the unit to be pivoted inwards by almost 180 degrees.
Tilting the units improves air flow and makes it easy to access all the frames for cleaning. Maintaining clear and sparkling glass has never been easier, with no compromising on the appearance or overall style of your windows.
The Slide Past Vertical Slider is arguably one of our most popular products across the entire range, and for good reason. Its slim sightlines blend unobtrusively with any internal décor making it a practical secondary glazing choice to improve comfort in all types of buildings, from period properties to modern apartments.
A unique feature of this variation is the ability of the panels to slide completely past one another to allow easy access for cleaning. The units are simple to operate, with brass rollers as standard to ensure a smooth sliding action within the frame.
