If you do nothing else to improve your home then you should reconsider when it comes out double glazing. It is by far the most singularly useful thing that you can add that will not only make your house warmer and cooler but it will also contribute to making it greener as well. Even better still you will see that your fuel bill starts to reduce. Here is why you should look at getting double glazing and this Double Glazing Evesham firm https://www.firmfix.co.uk/ are the best people to get in touch with first.
Double glazing is incredible at the art of insulation. You may associate insulation with keeping in heat. Cavity wall insulation, for example, and the loft insulation that you have in the eaves of the roof being another. As the heat from a fire or radiator starts to build up the last thing that you need is for that heat to bleed out via draughts and the windows. Unsurprisingly it is the windows that cause the most issues.
Single pane windows will not rebound and reflect the heat back into the house as double glazing will. Double glazing as a void between the panes, not a vacuum as many believe. This means that heat loss is greatly reduced. However, it does still happen.
Conversely it works with keeping the heat out. When the Sun shines in the summer months and the temperature starts to build, the heat cannot penetrate as much as it can through the single pane windows.
