Keep warm with our insulating interior window shutters.

With wholesale energy prices reaching an all-time high, it is no surprise that energy providers are having to pass on the cost to us consumers, and there doesn’t look to be a reprise anytime soon. When you combine this knowledge with the global effort to improve energy efficiency and preserve our precious natural resources, it is no wonder so many of us are eager to improve the thermal performance of our homes in order to make energy savings, improve heat gain and save money.

The best way to increase energy efficiency and help prevent heat loss is to insulate your home. Aside from insulating your loft to stop or reduce heat loss through the roof and insulating your walls to keep heat in, we can also add insulation to your windows.

How do you insulate a window? One way could be to replace the entire window with a more energy efficient solution in terms of glass, window frame and locking system, but this can be expensive. A simpler and lower cost alternative is to install window shutters to add an extra layer of insulation to your windows.

Let’s talk U-Value…

A U-Value measures how effective a material is an insulator and therefore how successful it is at reducing heat loss. Basically, the lower the U-value measures are in your home, the more energy efficient it is. According to The British Blind and Shutter Association (BBSA), a standard double-glazed window typically has a U-Value of 2.9. By adding wooden shutters, you could improve the U-Value to 1.9 – that’s a 35% improvement. Plus, here at ShuttersUp we can go one step further, as an optional extra we can add an integrated blind that is built into the shutter frame removing any gaps around the extremities. The blind has a foil inside which helps further with trapping heat in.

Our entire range of shutter styles will provide you with a more energy efficient window, whether you opt for full height shutters, tier on tier, solid shutters or café style you will notice an improvement in keeping cold air out and heat trapped in your rooms. We would argue that plantation shutters offer even more insulation than that of curtains or blinds, or other window coverings. In fact, our customers would argue this too. In  a recent survey, we asked our entire customer database (all 9,315 of them!) if they thought their window shutters help prevent heat loss, and 56% of respondents said yes, they had noticed a reduction in heat loss since having their window shutters installed.  Plus, many respondents also commented that they do a better job than their old curtains or blinds.

Why wooden shutters? Not only is wood a natural insulator and therefore, energy efficient, it is a time-tested, high-quality, sustainable material that has been admired in homes for generations.

If you already have shutters at your windows, maybe you just need to consider the way you are using them in order to maximise their heat retaining benefits? In the morning, ensure your shutters are opened to harvest free solar energy and close them again at dusk to help retain the heat and maximise energy.

If you are considering new shutters, we would be happy to chat to you. As BBSA members we will be able to talk you through your options as well as the associated energy saving benefits of our products. We craft all our shutter panels bespoke for you and your requirements meaning there is not a window too small, large or a shape that we can’t work with (another unique benefit compared with finding roller blinds or curtains). Our shutter company is passionate about our work and the customers we meet – our shutters are made for you.
