Secondary glazing is a fantastic alternative to sash windows. It can be installed in a variety of ways. box sash windows is a double-paned window that can be placed inside the window frame you already have. It provides insulation and noise reduction, in addition to blocking cold air from entering your 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 reduced condensation. Which is the best choice for you? The fundamental idea behind secondary glazing is the installation of an additional glass pane within the window frame. This adds an additional layer of insulation and soundproofing, which can significantly increase the efficiency of your home's energy use. However it's not always feasible to add new double-glazed windows to your home, especially if you live in a listed structure or are subject to strict planning regulations that define what can and can't be done to your exterior. In these instances, secondary glazing is a great alternative that can be put in with ease. It's also a popular choice for those who want to modernize their home without the need to tear down the original windows with sash and replace them with new ones. There are several different systems for secondary glazing on sash windows. Each one can be configured to fit into your existing frame. Proprietary systems are generally made of painted aluminium frames that fit into the existing bead depth on windows with sash. This lets shutters and sills remain. They can be equipped using a variety of methods for installation, like glazing clips or Velcro. These are more appealing than screw-fixed ones and are ideal for windows that do not need to be opened often. Alternatively, you can choose an adjustable lift-out unit, which can be lifted out and put back in place with ease to allow windows to be opened. Horizontal Sliders Horizontal Sliders provide excellent thermal insulation and are the most well-known option for enhancing existing windows with sash. They are also quiet and ideal for historic properties as well as conservation areas and listed property. In most instances, they can be installed without external access because they operate from the inside. They are simple to operate by hand and can be opened wide or left partially open for ventilation. They are very effective in eliminating draughts and offer the added benefit of removing harmful UV light. They can be used in conjunction with a flyscreen to ward off mosquitoes and other insects during summer months. Trackglaze horizontal sliding systems give all the advantages of double glazing for your original Sash window. It is comprised of PVC double sliding track on all four sides of cavity, a simple brush seal around each glass sheet and a handle for a finger pull angle to function as a hand, reducing bowing. It is available in kits of 1m or 2m of track and angle that can be stacked together to create larger spans. The acoustic benefits of second glazing are very significant and can dramatically enhance noise reduction from outside, especially road, rail & airport traffic. The addition of laminated or toughened 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 more impressive levels of acoustic performance. It can increase the energy efficiency of your home by keeping it warm for longer. This will decrease your reliance on central heat. It's much less expensive than replacing your sash windows, and can be installed almost everywhere without the need to remove the existing window or door frame. Vertical Sliders Secondary glazing is a cost effective alternative that is usually more manageable than full window replacement. It is also suitable for Listed Buildings & Conservation Areas. It's the ideal option for upgrading traditional sash windows in Suffolk & Essex with modern insulation benefits while keeping the character of older homes. Vertical Sliders were developed to be used in sash window applications in which hinged panels from the standard range are not suitable. The system is comprised of two secondary sashes, which are secured one above the other inside an outer frame. They are supported by spring balances, allowing for easy movement. The system is available as a 'face-fixed' (installed to the inside of the window) for improved thermal performance or a 'reveal-fixed' version which comes with a glass to glass cavity inside the window reveal, to ensure optimal acoustic performance. They can be equipped with a variety stops and handles to accommodate the preferences of the homeowner and can be used to prop open the bottom or top pane to allow for ventilation, or they can be secured in a closed position for added security. They can be fitted with an insulation bristle to block drafts. The 'Choices' vertical slider secondary glass features all the authentic wood detailing you'd expect to find in a period window treatment. It is available in a variety of colours that are compatible with your sash. It's almost impossible to tell apart from the original sash window, with details such as sash horns & traditional butt joints being incorporated into the design. It's available in a wide range of sizes and accepts glass up to 6.8mm to give additional insulation against heat loss. The tilt-in option permits the sashes of each window to be hinged inwards to make it easier for cleaning. Hinged Casement The single-pane hinged secondary glazing can be incorporated into windows in sash of any design including casement and traditional box sash. The hinged units we offer are made with secure multi-point locking and can be supplied with keys lock handles. This will ensure that the glazed panel is locked in place and is pulled tightly to the outer frame, forming a seal to minimize heat loss. Hinged windows are available either side or top hung and can also be constructed by double-glazing. Double-glazed windows provide better acoustic performances and are available in 43dB (for 47dB) or 51dB (for 51dB) or 47dB (for 49dB). In contrast to horizontal sash windows which have movable sashes that slide horizontally within the frame casement windows are able to open outwards and catch breezes from various angles. They can also be opened from the top and bottom to offer controlled ventilation. They are therefore able to improve airflow, and offer a fantastic alternative to traditional sash window. They are used in modern homes due to their narrow “sightlines” that permit clear views, however they can also be installed in listed homes since they do not require mullions and transoms. They're also a good option for those who live in areas that are difficult to reach as they can be opened with the flick of a handle. This type of window can be a problem as it may limit the use of certain window treatments. They can also be difficult to clean because they swing outward and may require regular maintenance and servicing. Lift Out Windows Secondary glazing can be installed in a variety of ways and the cost will differ according to the thickness, type and materials you select for your frame and panes. uPVC frames are the least expensive, followed by aluminium and wooden frames. Specialized glass, in addition to any additional features like security or sound reduction may also raise prices. The complexity of the installation will also affect the cost. The more complicated the project will take longer and require more labor it will require. This is also true for historic properties with more complex sash windows that require expertise and knowledge. Assessing the condition of windows in use is a good way to begin. You can get an accurate estimate of the cost by having them examined by professionals. In general, secondary glazing will have little impact on the overall appearance of your home. This is thanks to the fact that modern FINEO double glazing is sleek and subtle frame lines, which means you can get the most efficient thermal performance without compromising on aesthetics. The horizontal sliding secondary glazing option is popular due to its easy access to the existing sash window for cleaning or ventilation. These windows also come with a tilt function, which can be activated by opening the catch and then lifting your secondary glazing panel vertically to a predetermined degree. This is ideal for windows that don't open often and can be used to make it easier to access air cooling in bay windows. You can even use them to open up the middle sash of a traditional sash bay window to create a more uniform look.
