Secondary Glazing For Sash Windows Many homeowners are not able to add new double glazing to their homes due to financial constraints or because they reside in listed buildings that restrict any modifications to the exterior. Secondary glazing is an excellent alternative to sash windows. It can be put in various ways. It's an additional pane of glass within the window frame that prevents cold air from getting into your home, while also offering insulation and noise reduction. Fixed Inserts There are a variety of styles of secondary glazing for Sash windows. Each style has each of its own benefits ranging from increased security to reduced condensation. Which is the best choice for you? The fundamental idea behind secondary glazing is to install an additional pane of glass within the window frame. This adds a layer of insulation and noiseproofing to your home, increasing its energy efficiency. It's not always practical to install double-glazed windows particularly if you live in classified as a historic property or you are bound by strict planning regulations dictating what can and cannot be done to your exterior. Secondary glazing is a fantastic alternative in these circumstances. It can be put in relatively easily. It's also a popular option for those looking to upgrade their home without having to tear down the original sash windows and replace them with contemporary ones. There are many different options for secondary glazing sash windows, each one of can be customized to fit the frame you have. Proprietary systems typically have painted aluminium frames that are made to fit within the depth of a staff bead on an existing sash window, which means that sills and shutters can still be retained. They can be equipped using a variety of methods for installation, including glazing clips or Velcro. They offer a more stylish solution than screw-fixed units, and are ideally suited to windows that aren't required to be opened often. Alternately, you can choose a fixed lift out unit, which can be lifted and put back in its place with ease to allow windows to be opened. Horizontal Sliders Horizontal Sliders offer excellent thermal insulation and are the most popular solution for improving existing windows with sash. They are also extremely discreet and ideal for historic buildings, conservation areas, and listed properties. In most cases, they can be installed without access from outside because they operate from inside. They are simple to operate using a hand, and can be opened wide or left partially open to allow for ventilation. They are very effective at stopping draughts and also offer the added benefit of filtering out harmful UV light. They can be used in conjunction with a flyscreen to keep out mosquitoes and other insects during summer months. Our Trackglaze horizontal sliding systems offer all the benefits of modern double glazing to your traditional sash windows. It consists of PVC double sliding track that runs across all four sides of cavity and a simple brush seal around each sheet of glass and a finger pull angle handle to function as a hand and reduce bowing. It is available in kits of 1m or 2m of track and angle that can be put together to create bigger spans. Secondary glazing can have a significant impact on noise reduction, specifically for rail, road and airport traffic. The addition of laminated or toughened glass can further improve acoustic performance. Standard secondary glazing reduces outside noise to 52dB (Rw) and special glass, like Stadip Silence Laminated Acoustic Glass can provide even more impressive levels of acoustic performance. It can increase the efficiency of your house by keeping it warmer longer. This will decrease the need for central heating. It's less expensive than replacing the original sash window and can be installed without the need to remove the existing frame. Vertical Sliders Secondary glazing is an affordable option that is often more manageable than a complete window replacement. It's suitable for Listed Buildings & Conservation Areas. It's a great option to upgrade sash windows in Suffolk & Essex with modern insulation benefits while keeping the traditional look of older homes. Vertical Sliders were specifically designed to be used in sash window applications in which hinged panels from the standard range are not suitable. They come with two secondary sashes that are secured, one over the other, within an outer frame and are supported by robust spring balances that allow for effortless movement. The system is available as a 'face-fixed' (installed to the inside of the window) to improve thermal efficiency or a'reveal-fixed' version which is fitted with an air cavity for glass inside the window reveal, to ensure optimal acoustic performance. They can be fitted with a variety of handles and stop strips to meet the needs of the homeowner, propping open either the top or bottom pane for ventilation, or they can be fixed in an open position for additional security. They can also be fitted with an insulating bristle seal that can stop draughts. 'Choices’ Imagine vertical slider secondary glass has the same authentic wood details you'd expect to find in a period window treatment. It is available in a variety of colours that match your existing sash. It's nearly impossible to differentiate from the original sash windows, since details such as sash horns and traditional joints are included in the design. It comes in a variety of sizes and can be fitted with glass up to 6.8mm for additional insulation against loss of heat. A tilt-in option is available that allows the sashes to be hinged into the safety stays to help with cleaning. Hinged Casement Our single-pane hinged secondary glazing can be fitted to sash windows of any style, including casement and traditional box sash. Our hinged units can be supplied with a keylock handle, and are manufactured with multi-point locking. This ensures that the glazed panel is secured and is pulled tightly to the outer frame, forming a seal to reduce loss of heat. Hinged windows are available either top or side hung and are also available as double-glazed. Double-glazed windows offer enhanced acoustic performance and are available in 43dB, 47dB or 51dB. Contrary to horizontal sash windows with movable sashes that slide horizontally within the frame, casement windows are able to open outward and capture breezes from various angles. They can be opened both from the top and bottom to allow controlled ventilation. They are therefore able to improve airflow and offer a fantastic alternative to traditional sash window. They are popular in modern homes due to their small “sightlines” that allow for an unobstructed view. However, they can also be incorporated in listed buildings since they do not require transoms and mullions. They're also a good option for areas that are difficult to access as they can be opened with the turn of a handle. This kind of window could be a disadvantage because it can restrict the use of certain window treatments. They can also be difficult to clean because they swing outward and may require regular maintenance and service. Lift Out Windows Secondary glazing can be put in place using a variety methods. The cost will differ depending on your preference of the materials, thickness, and type of glass. UPVC windows are generally the most affordable followed by aluminium, and then wooden window frames. Specialized glass may also increase the cost and also any 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 labour will be required. This is also true for heritage properties that have more complex designs for sash windows. The best place to begin is to evaluate the condition of your current windows. You can get a precise estimate of the cost by having them examined by a professional. In general, secondary glazing has an insignificant impact on the appearance of your home. Modern FINEO double-glazing features slim and distinct frame lines. This allows you to achieve thermal efficiency without compromising aesthetics. The horizontal sliding secondary glazing option is a popular choice because it permits easy access to the existing sash window to clean or for ventilation. They also come with a tilt feature that can be activated by releasing the catch and then lifting the secondary glazing panel vertically up to a certain point. This is perfect for windows that don't get frequently opened. 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 the traditional sash bay windows to create a more uniform look.
