Dual glazing as opposed to triple glazing: which is the best?

There are many considerations that need to be taken into account while weighing up the pros and cons of double glazing versus triple glazing before the distinctions between these two glazing choices can be fully understood.

Unfortunately, the fact that double glazing uses two glass panes and triple glazing consists of three is much more complicated than that.

Although sandwiching an extra glass panel into a window would certainly result in huge thermal efficiency gains, it also brings with it other implications. In order to determine which is the best option for your house, consider the impact the extra panel will have on:

  • Energy efficiency 
  • Stress on window hardware due to increased weight
  • Cost implications

Hopefully, this article will outline all the implications so that you can make an informed investment decision based on all the most relevant facts, regardless of which option you eventually choose.

What is a triple glazed window?

Instead of one or two, triple glazing consists of three glass panes. Typically, the cavity between each glass panel is filled with an inert gas like argon, xenon, or krypton. This can help reduce noise propagation and increase energy efficiency in combination with the extra plate of glass.
