Horizontal Sliders

This type of secondary glazing is most frequently used as it can be applied to high rise or low level commercial properties, historical buildings as well as domestic dwellings. This system provides solutions to problems created by noise.

How It Works

This system is available in two, three or four paneled versions and the sashes are fitted with brass rollers providing the smoothest sliding action. Twin brush seals provide excellent high sealing efficiency. This has been proven to eliminate drafts and increase thermal insulation but also give greater improvements to the security of the primary windows. The security i also enhanced with the use of the latest handles and locks.

Vertical Sliders

The Balanced Vertical Slider is the most common complex type of secondary system. This is due to the characteristics of the existing primary window.which is suited to the upgrade and refurbishment of the nations 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.

Hinged Units

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 of 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 and can be secured by use of a multi-point locking system actuated by a single handle anti-ligature detail and gear box. The ability to utilise Tilt and Turn gearing also increases the flexibility of use, giving high level ventilation and a secure night vent position, whilst retaining easy access to the primary glazing for cleaning and general maintenance.

Lift Out Units

Economically, the Lift Out is the most cost effective type of secondary glazing available. It’s most common application is where limited access to the primary window is required, for example a window which has been installed will the sole objective of providing light to 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 a double brush pile seal, further increasing the thermal and sound insulation properties.

I had a problem with a water leak and when it was mended I was left with floor boards lifted and a huge mess. Scott came with no prior notice and fixed and repaired everything.
