Secondary Glazing
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 - Sound Reduction
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.
Glass options
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.

Benefits of secondary glazing - Thermal Insulation
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.
Glass options
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
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.

Vertical Sliders
Due to the characteristics of the existing primary window, the balanced vertical slider is the most complex type of secondary glazing system. It is designed to match the sightlines of traditional sash windows and is applied generally to older properties. It is particularly suited to the refurbishment and upgrade of the nation's architectural heritage.
Tilt in vertical sliders are also available providing a hinged opening for an alternative means of ventilation and access to the primary window without compromising on the all-important sightlines match. These tilt in versions can be pivoted through almost 180 degrees - a real benefit when it comes to cleaning them, but often a crucial consideration to meet fire escape requirements.
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 developed to withstand decades of wear and tear. All variations of exclusive secondary glazing styles from Falcon Windows Ipswich are completely compatible. Each type can be easily used with another no matter what the application may be.

Benefits of Vertical Sliders and Tilt in Sliders
- Matching sightlines - no distraction from the styling of the existing sash windows, retaining the building's style and aesthetics
- Improved thermal insulation - keeping your home warmer and without draughts from the windows
- Reduction of noise - minimising sound pollution
- Improved security - an additional level of security for aging or less secure primary windows
- Eradication of condensation - reducing the risk of mould, water ingress, damp and rot
- Easy access to primary windows for ventilation, maintenance and cleaning
- Affordable and low on maintenance.
Lift Outs
Economically, the lift out is the most cost-effective and basic 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 its name suggests, the lift out is a glazed unit which simply lifts out of or slots into a secured channel. For practical purposes, it is important to consider the sash size as the weight of glass must be of manageable proportions. The lift out is really best suited to smaller scale windows (up to 2m x 2m).
Each sash has a double brush pile seal, further improving the unit's thermal and sound insulation properties and keeping moisture levels in your home under control by eliminating condensation.
Benefits of the Secondary Glazing Lift-Out Panel
- Retained sightlines and unobscured view - single panel does not interfere with existing aesthetics, so potentially suitable for small-paned windows and even mullion windows.
- Eliminates draughts from windows and improves thermal insulation
- Reduces noise pollution
- More secure than primary windows alone, especially where primary windows are old or aging
- Makes condensation a thing of the past - no risk of mould, water ingress, damp and rot
- Cost-effective and affordable
- Very low maintenance, especially if left in position all year round.
Hinged Units
Enjoy the unobscured views of a lift out panel, but with the convenience of being able to open the secondary glazing for ventilation and cleaning. When it comes to providing an unobtrusive secondary glazing system, the hinged unit provides a transom-free, mullion-free solution. The units are particularly strong and versatile. The reduction in noise, improvement in thermal insulation and elimination of condensation greatly enhance both the living and working environments.
There are two types of hinged unit. Regular hinged units are manufactured to open on a restricting friction stay. For larger scale windows, the secondary glazing hinged units have the friction stay replaced with a butt hinge, carefully developed and rigorously tested to support differing weights of the glass 'leaf'. Double hinged units have been primarily designed to fit in front of larger windows or French doors, utilising the same range of hinges.
Practical Benefits of the Secondary Glazing Hinged Units
- Can be top or side hung
- Choice of hinge positioning on side hung units (left / right) - for convenient, easy opening
- Operating handle can be fitted at any convenient position or height
- All sizes of glazing unit can open up to 180 degrees, thanks to the extremely durable butt hinges which can support up to 120kg of weight.
