Vertical Sliders

The Product

Due to the characteristics of the existing primary window, the Balanced vertical Slider is the most complex type of secondary glazing system. It is applied generally to older properties. It is particularly suited to the refurbishment and upgrade of the nation’s architectural heritage.

How it works

The individually pre-tensioned spiral spring balances control the motion of the sash, enabling infinite vertical positioning. This design provides ease of movement and has been specially developed to withstand decades of wear and tear. Tilt in versions can be pivoted through almost 180 degrees. This is especially useful for cleaning

but just as importantly can be crucial when considering fire escape requirements. All variations of Granada’s exclusive secondary glazing styles are completely compatible. Each type can be easily used with another no matter what the application may be.

 


 

Horizontal Slider

The Product

Without doubt the most versatile type of secondary glazing, ideally suited to large glazed areas with minimal sight lines, the system offers a high level security with easy access to the primary glazing.

How it works

A robust system with a broad range of glazing capabilities, they can be hung on either butt hinges or concealed stays & is secured by use of a multi point locking system actuated by a single handle anti-ligature detail & gear box. The ability to utilise Tilt & Turn gearing also increases the flexibility of use, giving high level ventilation & a secure night vent position, whilst retaining easy access to the primary glazing for cleaning & general maintenance.

 


 

Hinged

The Product

When it comes to providing an unobtrusive secondary glazing system, the hinged unit provides the most appropriate solution, since there are no transoms or mullions to spoil the view. The reduction in noise, and improvement in thermal insulation, greatly enhances both the living and working environments.

How it works

The hinged unit can be manufactured in two main types. The single hinged unit opens on a restricting friction stay. Where the application is on a larger scale, the friction stay is replaced with a butt hinge. We have developed and rigorously tested a variety of butt hinges for differing leaf weights. The double hinged unit has been primarily designed to fit in front of larger Windows or French Doors, utilising the same range of hinges.

Lift Outs

The Product

Economically, the Lift Out is the most cost effective type of secondary glazing available. Its most common application is where limited access to the primary window is required, for example a window which has been installed with the sole object of providing light to a room.

How it works

As well as economical, the Lift Out is also the most basic form of secondary glazing. As its name implies, it simply lifts out of a secured channel. For practical purposes, it is advised that the sash size be considered since the weight of glass must be of manageable proportions. Each sash is manufactured with double brush pile seal, further increasing the thermal and sound insulation properties
