Window Insulation: Could Shutters Save You Money On Your Heating Bill?

Window insulation

Are you looking for smart ways to save money on your heating? Want to find out how shutters could reduce heat loss in your home? Looking for window insulation? You’re in the right place.

Windows are responsible for around 18-30% of the total heat loss in your home. This is a considerable contribution to your heating bill. You’re constantly losing warmth through your windows, even with double glazing.

Shutters might be an unexpected way to save money and keep the heat in, but we’ve put together everything you need to know.

How Shutters Help With Temperature Control

How exactly could shutters improve temperature control in your home? Shutters are an effective way to improve window insulation and keep your home at a consistent temperature year-round. This is because high quality and well-made shutters block any heat that may escape through your windows.

It works the same way when you want to keep the heat out. Sunlight and atmospheric heat can’t get inside your home as easily through windows, keeping your house interior cooler for longer.

Shutters are better insulators than curtains or fabric blinds because of their construction, usually wood or vinyl. When it comes to the technical side of temperature control in the home, it’s an insulator’s R-value that matters. 

What’s R-Value & Why Should You Care?

R-value is a measurement of resistance to the flow of heat. The higher the number, the better, which means a material provides better insulation.

Plantation shutters that are expertly installed have a 4.0 R-value when made of wood. Meanwhile, standard roller blinds achieve an R-value of 1.5, which gives you an idea of the difference shutters can make. 

When it comes to window insulation, there are insulating blinds, like Luxaflex Duette, that have a unique internal honeycomb structure that helps insulate your home. But back to shutters… 

In short, the internal construction of shutters means they keep your home warmer in winter and cooler in summer. 

Windows Insulation

Warmer In Winter

On a chilly or even icy day, you wouldn’t leave your windows wide open, especially if your heating was on. Having your windows open and exposed would allow precious heat to escape outside. You’d be wasting energy – and money – on heating.

Without shutters, this is basically what you’re doing. Shutters create a thermodynamic barrier, making it harder for heat to escape your home. Even the most energy-efficient windows are still a source of heat loss.

Shutters that are properly and securely installed become your last line of defence against the cold and offer additional window insulation. 

Cooler In Summer

On hot days you want to create an airy and cool atmosphere within your home. Shutters can help with this in a unique way. Solar shading with shutters manages the amount of natural sunlight entering a room to regulate temperatures indoors.

In the summer, you can use solar shading to your advantage by keeping shutter louvres closed on the sides of your home facing the sun.

Manipulating the amount of sun entering each room, allowing the exact amount of warmth and light to filter through your shutters, instead of each room simply being flooded with daylight or blocked out entirely.

How To Use Shutters To Maximise Window Insulation In Your Home

To maximise how energy efficient your shutters can be, you can follow these steps daily:

  • Open louvres in the morning to make the most of the early sunlight
  • Keep louvres open during daylight or sunnier hours to use the natural warmth of the sun to maintain heat inside
  • Close louvres before sundown to reduce heat loss
  • Keep louvres closed on overcast and cold days to maintain internal temperatures

Plantation Style
If energy efficiency is a priority for you, then plantation-style shutters are a winner. Properly fitted, this style of shutter provides reliable and noticeable thermal insulation by creating a barrier to hold warmth inside while also being adjustable.

Solid Panel
A solid panel shutter provides an unbeatable layer of protection against the cold and the glaring sun. The panel construction means less opportunity for heat to make its way out through your windows but also gives you the flexibility to concertina the panels to adjust for light and airflow.
