The adage “Two is better than one” has always been relevant. It has stayed true to almost all aspects of our lives, and homemaking is but a prime example. For those who are building their dream home or dreaming it up (for now), this is the best application of the two-vs-one principle.


Enter the double glazed window. Before bringing out the budget books, let’s first define what it is. Notably popular in countries with colder climates, this type of window doubles the glass material versus its singular counterpart. Its popularity is due to its insulating properties, which protects the home from various conditions. 


The average cost of a double glazed window ranges from $180 to $500, but a price of $1,000 and above is not uncommon. Ultimately, it is a bit pricey, but winter’s temperature makes it a good reason to invest. Still dubious? Set the frets aside -- We have put together a quick guide to get to know this type of window and what will fit best for your home.


What are the advantages of double glazing windows?

The double glazing windows cost can surely take you aback, especially since it is steeply priced to get into. However, it is better to consider this as an investment rather than an expense. 


But aside from insulation, what are the other advantages of having a double glazed window?


Added protection

The strength of a double glazed window will not only keep the heat in and out of your home, but the burglar beatniks too. Due to the added second layer, the probability of intrusions within your house will lessen because breaking in two glass panes is hard to come by. The breakages will lessen as well, which will contribute to a higher amount of savings in the long term. 


Long-term savings

When you think about double glazing windows costs, it might make you reconsider at first. But if you look and envision farther than your cost calculator now, you will realise that you saved more in repairs than you’ll ever dream of. 


One of the biggest advantages is reducing energy costs. Rather than having your heater constantly on blast to accompany the shivers, a double glazed window acts as your first layer insulator. It will also have you switching on the radiator occasionally rather than always, which can help lower your electric bills come the succeeding months. 


Noise-cancelling

The busy streets and bustling crowds are tolerable in the day but can be troubling to your sleep cycle during the evening. If noise-cancelling headphones are not what you have, a double glazed window is the surest deal to have in your arsenal. 


Its insulating properties drown out the noise heard outside, so you can get a good night’s sleep while the world goes on outside.

What is the cost of double glazed window replacement?

Like with everything else, there is a time where repairs come calling. A misted double glazed window replacement can cost around $100, plus the labour costs. 


But how do you know when to replace it? Here are some factors you need to look out for:


Frayed frames

Vintage frames look pretty in pictures but sadly decrease the effectiveness of your double glazed windows. When the wood starts to sag, it is time to call for a replacement. Frayed frames are not effective in insulating the home from cold air so best to ring in before winter. 


Condensing panes

The act of condensation is a process crucial to nature but can be damaging to your windows. When they start condensing or misting, that’s a sign of weak seals in your panes. Once this happens to your set, it is time to fully replace them. 


Increase in cold air

This is the most obvious sign of all is it runs counter to the sole purpose of these windows. Double glazed windows decrease the entrance of cold air into the home, so when the cold drafts become more bothersome, repair works should be on the way.
