Double vs. Triple Glazing
People are constantly discussing whether double or triple glazing is better. When taking into account the pros and cons of the two, there are several aspects to consider before you can fully understand all the differences between these two options.
Much the pity, the biggest difference between double and triple glazing isn’t simply that double glazing features two panes of glass while triple glazing features three. Though it’s obvious that adding that extra pane of glass to a window will work wonders in terms of insulation and soundproofing, the whole picture is a bit more complicated than that.
In order to decide which option is best for your home, you should think about the effect of that extra pane of glass on:
- Energy efficiency
- The advantages and disadvantages of the window itself
- The cost impact
We hope that this website will help you get a general understanding of the impacts so that no matter what you chose, your decision is informed and based on all the facts.
Is double glazing worth the price?
