Secondary double glazing from Falcon Windows is ideal for period properties, where window replacement is not an option. It is practically invisible from the outside and unobtrusive on the inside, allowing added comfort and security without disturbing the view.
Secondary double glazing is a discreet substitute to plastic uPVC windows, particularly suited to installation in listed and conservation properties in Ipswich and Colchester
Reducing drafts, heat loss, condensation and noise, our sound proof secondary glazing in Ipswich has the ability to lower noise values from outside as well as make a significant difference to the insulation of the property. Many of our customers have commented how neat the secondary double-glazing looks and how it blends into the sash windows which their listed property has had to retain for planning reasons. Don't just take our word for it - hear, see and read what our customers have to say..

Benefits of secondary glazing
Secondary glazing is an effective method of reducing noise pollution, whether you are looking to guard against noise, road traffic, or retain noise, for example pubs and clubs.
How is noise insulation achieved?
By increasing the gap, otherwise known as 'cavity', between the existing window and the secondary frame, the better the sound proofing becomes. We suggest a minimum cavity of 100mm for increased sound reduction. Road traffic noise pollution can be reduced by around 70-80% and can be reduced further by using acoustic glass.
There is a wide range of glass options available to ensure optimum sound reduction. The main objective when aiming to reduce levels of sound pollution is to use glass which is a different thickness to that in the existing window. By using glass of different thicknesses, sound transmits at different frequencies, thus improving sound reduction. Acoustic laminate can also be used - this has a special interlayer, which is particularly good when trying to reduce high frequency noise, for example aircraft noise.
Windows tend to be a prime area for heat loss, which can be significantly reduced by introducing secondary glazing. Improved thermal insulation can help to save energy and, in turn, lower fuel costs.
Secondary glazing also helps to eliminate draughts, improving comfort and reducing the level of airborne dust getting into a building.
The use of secondary glazing can help to meet the standards set out in Part L of the Building Regulations, which are set to change in October 2010 with the introduction of Energy Performance Certificates. These certificates will define a building's energy rating and will become a factor in property valuations.
By introducing secondary glazing, even with standard clear glass, you will improve the thermal insulation of your home, but for optimum results use Pilkington K Low-e glass. 'Low emissivity' (Low-e) glass such as Pilkington K Glass is designed to reflect heat from fires and radiators back into your home, greatly improving its thermal efficiency. Also, it allows heat from the sun through your window, contributing to its energy efficiency. By using less heat to keep your home warm, less energy needs to be produced, therefore lowering the overall levels of greenhouse gases and the cost of keeping your home warm.

Need to know - Types & components in secondary double glazing
Horizontal sliders are undoubtedly the most frequently used type of secondary glazing. This sort of secondary double glazing is to be found both in high rise or low-level commercial properties, historic buildings as well as all kinds of domestic dwellings.
The Falcon system provides sensitive solutions to the problems created by noise and sound pollution.Generally available in two, three or four panelled versions, the sashes are fitted with brass rollers, ensuring the smoothest sliding action. Twin brush seals provide excellent high sealing efficiency. This has been scientifically proven to eliminate draughts, increase thermal insulation and give greater improvements to the security of the primary windows. The security issue is further enhanced with the use of the latest locks and handles.
Due to the characteristics of the existing primary window, the balanced vertical slider is the most complex type of secondary glazing system. It is applied generally to older properties and particularly suited to the refurbishment and upgrade of the nation's architectural heritage.
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. All variations of Falcon's exclusive secondary glazing styles are completely compatible. Each type can be easily used with another no matter what the application may be.
Economically, the lift out is the most cost effective type of secondary glazing available. Its most common application is where limited access to the primary window is required, for example a window which has been installed with the sole object of providing light to a room.
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 double brush pile seal, further increasing the thermal and sound insulation properties.
The hinged unit can be manufactured in two main types. The single hinged unit opens on a restricting friction stay. Where the application is on a larger scale, the friction stay is replaced with a butt hinge. We have developed and rigorously tested a variety of butt hinges for differing leaf weights. The double hinged unit has been primarily designed to fit in front of larger windows or French doors, utilising the same range of hinges.
When it comes to providing an unobtrusive secondary glazing system, the hinged unit provides the most appropriate solution, since there are no transoms or mullions to spoil the view. The reduction in noise, and improvement in thermal insulation, greatly enhances both the living and working environments.
Whichever type of secondary double glazing you choose, Falcon Windows in Ipswich will install them to the highest standards. We pride ourselves on our expertise and real personal service. Why not give us a call and see how we can help now?
