SECONDARY GLAZING VS DOUBLE GLAZING

There are still some properties here in the UK that have single glazing windows and unfortunately, the people who own these properties experience a number of problems with their windows. Due to the fact that these windows only contain a single pane of glass, not only are they known for having poor insulation and causing draughts throughout the home, but they are also a security issue and much easier to break too.    It is no surprise that many who have single glazed windows will search for a way that they can upgrade these and homeowners will often be presented with two different options; secondary glazing and double glazing. Whilst it can be easy to assume that these two types of windows are the same and even though their name is similar, they are actually very different. So, to help any homeowners who are wanting to upgrade their windows, below is everything you need to know about these two types of windows.   

What are secondary glazing windows?

  Simply put, secondary glazing involved adding an independent system into the inside of an existing single glazed window frame. You will essentially be installing an additional layer of glazing to the windows and usually, this layer will be glass but it can also be clear plastic too.    From vertical sliders for sliding sash windows to horizontal sliders for casement windows, or hinged units and lift-out units for any style of window, there are a number of different types of secondary glazing to choose from too.   

What are double glazing windows?

  As the name suggests, double glazing is windows that comprise of two panes of glass which are separated by a layer of Argon gas. When installing double glazing windows, you will be completely replacing the existing windows at your property with a new sealed unit.    You can purchase double glazing in any style of window, from bay and bow to tilt and turn, so you easily install the same style you currently have if you’d like. You can also choose from a number of different frame materials and colours as well.   

Which type of window is best to choose?

  Ultimately, these two glazing options are completely different and when choosing between them be sure to consider the following;   

Durability 

  Whilst secondary glazing can be permanent, more often than not it is added as a temporary measure and it is likely that you will need to replace the windows at some stage. However, when you opt for double glazing, you are replacing the whole window with a much higher-quality unit, so you can have peace of mind knowing they will last for many years to come.    

Insulation

  Both secondary glazing and double glazing will increase the energy efficiency of your home, however, many experts say that double glazing is actually twice as effective as secondary glazing. You can rely on these sealed units to be thermally efficient, meaning they stop heat from escaping your home and prevent cold draughts from entering.   

Cost

  Secondary glazing is considerably more affordable than double glazing and you can even purchase DIY kits for a cost-free installation. That being said, even though double glazing is more expensive upfront, it is known for being cost-effective in the long run and homeowners can save hundreds of pounds every year on their energy bills for decades.  

Maintenance

  Generally speaking, double glazing is much easier to clean than secondary glazing, simply because you only have one window to clean rather than a window and an additional system. Being able to clean in between the single glazed window and the other layer of secondary glazing is essential, but it really can be quite fiddly.

  Hopefully, you will now know a little bit more about the differences between secondary glazing and double glazing.
