Energy efficiency is a hot topic for homeowners for two reasons: energy efficient home improvements can reduce household bills and increase house value, and they will also reduce your carbon footprint. As the UK and Europe scramble to try and achieve their carbon reduction targets, it’s imperative that we stop relying on gas and other fossil fuels for our energy, and start using renewable sources. Any efficient home improvements we can make will lower our gas consumption.
Double glazed windows are one of the top property improvements chosen by homeowners, because they keep homes at a warmer temperature. Double glazing also reduces outside noise which is another added benefit. But how is this type of window so much more efficient than a single pane window?
Double glazing works in three ways:
Double glazed windows have two panes close together, hence the name double glazing. There is a glass pane on the outside, a glass pane on the inside, and a small space in the centre known as an air gap or tight air pocket.
When heat energy is transferred from hot spaces to cold spaces we call it convection, but it requires a good conductor. The trapped air in-between the glass cannot circulate, so it is therefore a poor conductor, reducing the rate of heat loss from inside the house. With less heat able to leave the room through the window pane, the room stays warmer for longer.
Many double glazed windows are manufactured with PVCu or aluminium frames, which are both durable and efficient materials. There should be no small gaps around the window frames to allow cold air to enter the house.
By adding an extra piece of glass to your windows, you can vastly reduce heat loss and reduce the annual cost of your energy bill. Double glazed windows have a heap of other advantages too – for example two panes are much more difficult to smash than one, so they can further increase home security. They are guaranteed to add value to your home if you upgrade from single pane to double glazed windows, as they will increase the overall energy efficiency of the property.
