Fixed Inserts
There are many different types of secondary glazing that are available for sash windows. Each comes with its own set of benefits, from improved security to reduced condensation. Which one is the best option for you?
The fundamental idea behind secondary glazing is to fit an extra pane of glass within the frame of your existing window. This adds a layer of insulation and noiseproofing to your home, increasing its energy efficiency.
However it's not always possible to install new double-glazed windows to your property, especially if you live in a listed structure or are subject to strict planning regulations that dictate what can and cannot be done to your exterior.
In these instances, secondary glazing is a great alternative that can be installed with ease. replacing window sashes 's also a popular choice for those who want to modernize their old home without having to take down the original windows in sash and replace them with new ones.
There are many different systems available for secondary glazing sash windows, all of can be customized to fit your existing frame. 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 meaning that shutters and sills can still be retained.
They can be fitted using a variety of methods for installation, such as glazing clips or Velcro. These types of units look more attractive than screw-fixed ones and are ideally suited to windows that do not need to be opened often. You can also opt for an unfixed lift-out unit that can be easily removed and then reinstalled to open your windows.
Horizontal Sliders
Horizontal Sliders offer excellent thermal insulation and are the most popular solution to improve the performance of existing sash windows. They are also very discreet and are ideal for historic buildings, conservation areas, and listed properties. In most cases, they are installed without access from outside because they operate by the inside.
They are simple to operate with a hand and can be open wide or left partially open for ventilation. They are extremely effective in eliminating draughts and offer the added benefit of blocking harmful UV light. They can be used in combination with a flyscreen to keep out mosquitoes and other insects during summer months.
Trackglaze horizontal sliding systems provide all the advantages of double glazing for your original Sash window. It consists of PVC double sliding track that runs across all four sides of the cavity and a simple brush seal around each glass sheet and a finger pull angle handle to act as a hand and reduce bowing. It is available in kits with 1m or 2m of track and angle that can be put together to create larger spans.
The acoustic benefits of secondary glazing are very important and can enhance noise reduction from outside, particularly the airport, rail and road traffic. The addition of toughened or laminated glass further enhances the acoustic quality. Secondary glazing that is standard reduces outside noise to 52dB (Rw) and specialist glass, such as Stadip Silence Laminated Acoustic Glass, can achieve even higher levels of acoustic efficiency.
It can increase the efficiency of your home by keeping it warmer for longer and decreasing dependence on central heating. It is less expensive than replacing the original sash window and can be installed without the need to remove the frame.
Vertical Sliders
Secondary glazing is an affordable option that is often simpler to manage than a full window replacement. It is suitable for Listed Buildings & Conservation Areas. It's a great way to improve the look of traditional sash windows in Suffolk & Essex while retaining their originality.
Vertical Sliders were developed for sash window applications where hinged panels of the regular kind would not be suitable. The system is comprised of two secondary sashes, which are secured one over one within an outer frame. They are supported by spring balances to allow for easy movement. The system is available as a 'face-fixed' (installed to the inside of the existing window) for improved thermal performance, or a'reveal fixed' version which has an air cavity for glass within the window's original reveal, to ensure optimal sound quality.
You can choose from a range of stop-strips and handles to match your preferences. They can be fixed in a closed position for additional security or propped open for ventilation on the glass's top or bottom. They can also be equipped with an insulating bristle seal to keep out drafts.
'Choices' Imagine vertical slider secondary glazing has the same authentic wood detailing you'd expect from an antique window treatment and comes in an array of colours to match your existing sash. It's almost impossible to distinguish from original sash windows, as details like sash horns and traditional butt joints are incorporated into the design. It's available in an extensive selection of sizes and will accept glass up to 6.8mm to add insulation to prevent heat loss. The tilt-in feature allows the sashes of each window to be hinged backwards on safety stays for easier cleaning.
Hinged Casement
Our single-pane hinged secondary glass can be incorporated into sash windows of any style, including traditional and casement sash. Our hinged units are constructed with secure multi-point locking and can be supplied with keys and a handle for the lock. This combination ensures that the glass panel is securely locked in place and is pulled tightly against the frame, creating a seal to minimise loss of heat. Hinged windows are available as either side or top hung and can also be made with double-glazed. Our double-glazed windows provide enhanced acoustic performance and are available in 43dB, 47dB or 51dB.
Contrary to horizontal sash windows which have movable sashes, slide horizontally within the frame, casement windows are able to open outwards and catch breezes from different angles. They can also be opened from both the top and bottom to offer controlled airflow. Because of this, they can increase airflow and provide an effective alternative to traditional sash windows.
They are typically employed in modern homes since they have small "sightlines" and unobstructed views. However, they can also be fitted into listed properties due to the fact that they do not require transoms or mullions. They can also be utilized in areas that are difficult to access since they can be opened simply by turning a handle.
The main drawback of this type of window is that they can block off large openings and limit the use of certain window treatments. They are also difficult to clean as they swing outward, and could require regular maintenance and service.
Lift Out Windows
Secondary glazing can be set up with a variety of methods and the price will vary depending on the type, thickness and the materials you select for your frame and panes. Upvc frames are the most expensive followed by aluminium, and wooden frames. Specialized glass can also add to the price and include extra features, such as sound reduction or security.
Another factor that will influence the cost is the complexity of the installation. The more complex the project will take longer and more labor will be required. This also applies to heritage properties with more complex sash windows, which require expertise and knowledge.
Analyzing the condition of windows that are in use is a good place to start. The survey conducted by a skilled professional will give you an accurate estimate of what the cost could be.
Generally speaking, secondary glass will have minimal impact on the overall appearance of your home. This is thanks to the fact that modern FINEO double-glazing has slim and discreet frames, meaning you can attain thermal efficiency without sacrificing aesthetics.
The horizontal sliding secondary glazing option is popular because it allows easy access to the sash window to clean or for ventilation. It is also possible to get them with a tilt function which is activated by unlocking the catch on your secondary glazing panel and lifting it vertically to a preset point. This is perfect for windows that aren't opened very often. It can be used to provide air conditioning access to bay windows. You can even make use of them to open the middle sash of a traditional sash bay window to create a more uniform look.
