The Advantages of Secondary Glazing

Secondary glazing isn’t only an option for people who don’t want to replace their home’s original windows and window frames; it is actually one of the most effective ways of reducing noise too. There are many advantages to secondary glazing, but here are some of the best reasons that you might want to consider secondary glazing.

  • Noise Reduction

Secondary glazing has been shown to be the most effective method of reducing noise pollution. When you compare it with single and double glazing methods, secondary glazing reduces noise by between up to 70% and 80%. The reason that secondary glazing is so effective at reducing noise is the distance between the two panes of glass.

Double glazing uses two panes of glass that are 24mm to 28mm apart and have gas sealed between the two layers; secondary glazing uses two pieces of glass that are a minimum of 100mm away from each other. The type of glass that is used in secondary glazing is also one of the reasons that it is so effective at reducing noise. 6.4mm laminated glass is normally used in secondary glazing that reduces noise by roughly 40 decibels.

  • Cost

When it comes to any form of renovations to your home, cost is always a factor. Secondary glazing is much cheaper than replacing your original windows. If you were considering replacing your single glazed windows with double glazing, you will need to pay for new units to be installed, the gap between the new glazing panels to be seal and filled with inert gas, whereas secondary glazing simply adding a second set of window panes to supplement your existing ones.

  • Thermal Efficient

With the rising price of fuel, reducing heat loss and your energy bills are two areas where secondary glazing truly excels. Most people consider replacing single glazed windows because they aren’t very good at preventing heat loss. Secondary glazing is something of a wonder when it comes to reducing heat loss though.

As the secondary panes of glass are completely airtight, and the thickness of the panes is at least 4mm thick, you can almost complete eliminate heat loss through your windows by having secondary glazing fitted. You can then easily keep your home warm during the winter months and reduce your energy bills at the same time.

There is also the advantage that making your windows more thermal efficient, can add value to your home as well, making it an ideal solution if you are thinking of selling your home.

  • Security

One benefit that never occurs to many people is how secondary glazing can help to improve the security of your home. Secondary windows are extremely difficult to open from the outside and can also be fitted with laminated or toughened glass so that they are difficult to break too. If a thief is bargaining on a quick and quiet entry into your property, seeing that a property has secondary glazing can often deter thieves as it is harder to break in through two sets of windows than through single or double glazed units.

  • Building Regulations

Because you aren’t replacing your windows when you have secondary glazing fitted, you aren’t subject to the UK building regulations. This is incredibly useful if you happen to have a home that is listed as you don’t have to go through the approval process in order to get secondary glazing units fitted.

  • Eco-friendly

Secondary glazing is also environmentally friendly. Not only does it reduce the amount of heat loss and therefore also reduces the amount of energy that you use, the uPVC that is used in secondary glazing is usually made from aluminium. Aluminium uses less fossil fuels than other uPVC materials when it is produced. You also reduce the amount of waste you create when you have secondary glazing fitted as your original windows are not being removed and thrown into a landfill.

  • Condensation

Condensation is one problem that goes hand-in-hand with windows, and one thing that most UK homeowners would rather do without. Secondary glazing can help reduce condensation problems dramatically. During the winter months, when the temperature inside your home is much greater than that of the outside, you will find that condensation forms on the inside of your windows, something that can lead to mould growth, but it also isn’t very pleasant to have to live with either.

Because secondary glazing creates an extra barrier between the heat in your home and the cooler air outside, you reduce the condensation problem without having to do anything else.

  • Internal Environment

The final reason you might want to consider secondary glazing is how they can improve the internal environment in your home. If you have hay fever, you may find that your single glazing allows in pollen that aggravates your condition. If you have a dust allergy, you may find that your single glazed units prove ineffective at keeping dust out. Single glazing isn’t very effective when it comes to preventing cold draughts, pollen, pollutants and dust from entering your home. They are also subject to rattling and vibrating in the frames that can be extremely annoying if you live in an area where there is heavy traffic.

Secondary glazing gives you a sealed second barrier around your windows helping to reduce and prevent draughts, stop the ingress of dust, pollen and pollutants and reduce the irritation that is caused by the noise of vibrating and rattling windows.
