What is triple glazing?


As we’ve previously written, double glazing is simply the process wherein two identical pieces of glass are placed on top of each other with an air gap between them. This creates an incredibly effective layer of insulation between the two. This layer of insulation offers numerous benefits to the home, including increased energy efficiency and a level of soundproofing. 

Triple glazing is the next logical extension of this process: if one air gap creates a layer of insulation, two air gaps will create two layers of insulation.

What Are The Benefits of Triple Glazing?

There are a number of benefits associated with having triple glazing installed in your home. Many of these you will recognise from our previous articles on double glazing, or from your own experience with double glazing. But while double glazing may be good at being energy efficient, triple glazing is great at it – especially when it comes to sound and thermal insulation.

Sound Insulation

After you’ve had triple glazing installed, you will notice a significant reduction in external noise. This is great if you live on a main or busy road if you work nights, or if you just value silence in your home. 

Higher Energy Efficiency 

However, a higher level of sound efficiency is not the only improvement that you will notice. You will also notice a warmer house year-round. This is because the third level of glass ensures that heat loss is minimised. Of course, this will also mean that your energy bills will be lower 

Less Condensation

Another benefit associated with triple glazing is a much lower amount of condensation compared to both traditional glass and double glazing. This lack of condensation is a result of triple glazing’s thermal insulation properties. 


Alongside these other great benefits, triple glazing is also far harder to damage than other windows. As a result, having them installed in your home will yield an increase in your home’s value.

Triple Over Double?

Whilst triple glazing does things slightly better than double glazing, is it worth pulling one out for the other? Although yes there would potentially be a slight difference, for the cost of replacing well-fitted and sealed double glazing would outweigh the benefits.

However, If it is time to replace your windows, then moving onto triple glazing would be worthwhile in the long run.
