Secondary Glazing For Sash Windows

Many homeowners are not able to add double glazing to their house, either because of financial limitations or because the building is listed and exterior modifications are prohibited.

Secondary glazing is an excellent alternative to sash windows and can be put in various ways.

This is a double-paned window that can be placed inside the window frame you already have. It offers insulation and noise reduction, as well as blocking cold air from entering the home.

Fixed Inserts

There are many different styles of secondary glazing that are available for sash windows. Each style has each of its own benefits that range from increased security to less condensation. Which one is the best option for you?

The fundamental idea behind secondary glazing is to install an extra pane of glass within the frame of your existing window. This provides an additional layer of insulation and noiseproofing your home, increasing its energy efficiency.

It's not always possible to install double-glazed windows especially if your home is a listed property or you are governed by strict planning regulations that dictate what can and can't be done with your exterior.

In these situations, secondary glazing is a fantastic alternative that can be put in easily. It's also a popular option for those looking to upgrade their home without having to take down the original windows in sash and replace them with contemporary ones.

There are a number of different systems available for secondary glazing sash windows, all of can be customized to fit the frame you have. The proprietary systems typically feature painted aluminium frames that are made to fit within the depth of a staff bead on an existing sash window so that shutters and sills are still able to be used.

They can be fitted with a variety of installation methods such as glazing clips and Velcro. These offer a more aesthetic solution than screw-fixed units, and are especially suited for windows that aren't required to be opened often. You can also choose an adjustable lift-out unit that can be lifted out and then put back in place with relative ease to allow your windows to be opened.

Horizontal Sliders

Horizontal Sliders provide excellent thermal insulation and are the most sought-after solution to improve the performance of existing sash windows. They are also extremely discreet and suitable for older structures, conservation areas and listed properties. In most cases, they can be installed without having access to the outside since they operate from the inside.

They are easy to operate using a hand, and can be opened wide or left partially open for ventilation. They are very effective at eliminating draughts and offer the added benefit of filtering out harmful UV light. They can be used in conjunction with a flyscreen to ward off mosquitoes and other insects during summer months.

It is available in kits of 1m or 2m of track and angle that can be put together to create larger spans.

The acoustic advantages of secondary glazing are extremely significant and can dramatically enhance noise reduction from outside, particularly the airport, rail and road traffic. The inclusion of laminated glass or toughened glasses enhances the acoustic performance. Standard secondary glazing reduces outside noise to 52dB (Rw) and special glass, like Stadip Silence Laminated Acoustic Glass can deliver higher levels of acoustic performance.

Vertical Sliders were developed for sash window applications where regular hinged panels would not be suitable. They come with two secondary sashes which are secured to one sash above the other, within an outer frame and are supported by sturdy spring balances to allow for easy movement. The system is available as a 'face-fixed' (installed to the inside of the existing window) for increased thermal performance or a 'reveal-fixed' version which is fitted with a glass-to-glass cavity, within the original window reveal, to ensure optimal acoustic performance.

They can be equipped with a variety of stops and handles to suit the homeowner's preferences by allowing the top or bottom pane for ventilation, or they can be secured in the closed position to provide security. They can also be fitted with an insulation bristle to block drafts.

Hinged Casement

Our single-pane secondary glazing can be fitted on sash windows in any style, including traditional box sash and casement. Our hinged units are manufactured with secure multi-point locking and are available with keys and a handle for the lock. This combination ensures the glazed panel is held securely in place and is pulled tightly against the frame creating a seal designed to minimise heat loss.

Unlike horizontal sash windows, with movable sashes that slide horizontally within the frame casement windows are able to open outwards and catch breezes from a variety of angles. They can be opened both from the top and bottom for controlled ventilation. They can therefore increase airflow and offer a fantastic alternative to traditional sash windows.

They are commonly used in modern homes due to their narrow "sightlines" which allow for unobstructed view, but they can also be put in listed buildings since they don't require mullions and transoms. They can also be utilized in places that are difficult to reach since they are easily opened by turning a handle.

The primary disadvantage of this type of window is that they can block large openings and may restrict the use of certain window treatments. They can be difficult to clean, as they open outward. They could also require regular maintenance and care.
