Windows are a vital element in our homes, but what difference does a glazing make to our properties? 


Let’s Go to the Basics


What is ‘Glazing’?


Interestingly, the word ‘glazing’ descends from the Middle English period – it simply means ‘glass’.  As you can expect, double glazing has two panes of glass and triple glazing has three. 

In between the panes of glass is either a: ‘vacuum’ or pocket of gas. 

  • A vacuum is an ‘empty space’. More precisely, a space where gaseous pressure is lower than the atmospheric pressure. 
  • If there is a pocket of gas, it will be an inert gas such as argon, xenon or krypton. Inert gasses are chosen since they do not easily undergo chemical reactions.

Vacuums or gas pockets are chosen since they are able to inhibit convection and conduction currents without stopping the sun’s rays infiltrating. In simple words, you are able to have natural sunlight in your house without losing the heat from your property. 

Note: these methods are not 100% perfect since in a house, the window parameter is one of the highest areas of heat loss in the building alongside the roof. 


Double Glazed Windows


Double glazing is the most popular choice in UK homes because:

  • They have good energy-efficient properties
  • They are noise reducing
  • They are good at reducing heat loss from the property
  • They help save you money on your heating bills due to their thermal efficiency


Triple Glazed Windows


I won’t lie, I didn’t know that triple glazing was a ‘thing’ until last week. Maybe that is because they are not such a popular choice. Or, because unless you’re window shopping, it isn’t a common conversation topic. 

Anyhow, as you may expect a triple glazed window does the exact same as double glazing, only better.

This means that they are even more thermal efficient and noise reducing. In the long term, you could save even more on your heating bills with triple glazing than double. 


Are There Disadvantages of Triple Glazed Windows? 


As expected, triple glazing is more costly as it requires an extra pane of glass. However, you could potentially save the additional money you spent on triple glazing from the reduced heating bills over the years.

Moreover, some arguments have suggested that triple glazing reduces the amount of natural sunlight coming in through the windows. If this is the case, your house is less likely to feel the natural warming benefits of solar radiation. More so, individuals are less likely to receive the benefits of sunlight i.e. Vitamin D, as a result of the extra insulation.

Lastly, since triple glazing is heavier, you may require reinforcing of the structural elements around the windows to protect the property from stress-related structural damage. 


Windows in Huubs


Our Huubs are typically built with double glazing. However, we provide customers the option to upgrade to triple glazing if they wish. 

Our Windows are made from aluminum frames which are corrosive-resistant and highly durable. Due to the solid frames, the windows can last for up to 40 years – which is around 25 years longer than uPVC window frames. 

Moreover, our windows incorporate small sections of recycled plastic in the structural elements of the frame. Huub specifically uses recycled plastic to help reduce environmental plastic pollution and reduce the volume of plastic reaching landfill.


About Us:

Huub is a Dorset based, British company that constructs modular, timber framed, solar powered garden buildings. Huubs are built in an off-site facility in Dorset and offer a great opportunity to generate solar energy and add additional space to your home at a relatively low cost (approximately £1500 per m2).
