Making your home more energy efficient with Shutters

"Shutters can reduce heat loss in the home by up to 64%!"

As the impact of the cost of living and rising prices are being felt, many discerning homeowners are looking at how smart choices can make long term savings throughout their home. The great news is that they need to look no further than the dressings on their windows as an incredibly simple solution that can save some much-welcomed pounds each month.

Did you know window heat gain and loss is responsible for 25-30% of residential heating and cooling energy use?

Turning attention to your window dressing may just be the answer to making your homes energy usage more effective, and shutters happen to be the winning choice. As a custom manufactured product to the exacting measurements of a window, shutters are the most effective dressing choice for impacting the heat loss from window areas.

Shutters provide an extra insulating layer to boost the efficiency of window areas in the home and studies have shown that the addition of shutters to a window can help to reduce heat loss by up to a massive 64%.

Shutters aren't just brilliant at reducing heat loss in the home - they can also have a cooling effect in rooms during warmer summer months. The effectiveness of the shutters in both hot and cold months can assist with both standard heating bills as well as reducing the use of Heating, Ventilation and Air Conditioning units (HVAC) which are very costly to run.

Studies show that solar energy transmittance (gtot) reduces from 0.85 to 0.24 with a double-glazed window. Adding a shutter can reduce this further to 0.15 gtot. In London properties where overheating can be a problem in summer months, this gtot reduction can avoid the requirement of HVAC units and the cost associated with running them. Shutters are considered a non-energy intensive home solution as unless motorised shutters are installed, no power is required to make the shutters work.

Optimal usage of the shutters varies depending on the time of year and whether you want the shutters to help heat, or cool, your home. In summer, panels and slats should be closed when it’s hot outside and when any direct sun glare can shine through into the home, only re-opening when the sun has set or the window becomes shaded. This operation ensures that direct light doesn't heat the space during the hottest times of day and keeps rooms comfortably cool. Windows can also be opened behind the shutters and slats manoeuvred to slightly open to allow a slight breeze to come through.

In colder winter months, the best operation is to keep the shutters open throughout the day to allow light to shine through and warm up the room, harvesting the available solar energy to keep the room warm, and close again when it gets dark. 

 

A comparison

In a study which looked at the percentage reduction of heat loss in different shadings compared to single glazed windows, shutters were the clear front runners at 64% compared to 37% when a roller blind is used.

Honeycomb blinds were runners up to shutters in the percentage efficiency rankings. Honeycomb blinds can be fitted behind shutters as a room darkening solution or on their own in a custom-built frame to concertina up and down as required. Though honeycomb blinds work as a good darkening addition within a shutter frame, the blind alone does not offer the long list of shutter benefits including varying levels of light and privacy control so the combined option is most recommended. 

Thinking about your U-Value

U-value (also known as thermal transmittance) is the rate of transfer through a structure divided by the difference in temperature across that structure. The better insulated a structure is, the lower the U-Value will be. The most effective way to improve the U-Value, specifically in single glazed properties, is to swap out the windows however this option can be both lengthy and expensive. Focusing on the window dressing instead (either as a cheaper alternative or to boost the window performance) can improve the U-Value by 40% which is a significant improvement.

Protecting the planet one shutter at a time

As quantified by an ESCORP/EU25 study, up to 80 million tonnes of CO2 could potentially be saved by installing shutters and blinds so installing shutters to the windows won't just help your wallet, it will help your carbon footprint too.

I love my new blinds. They are high quality, look beautiful and were at the most competitive price. The fitters were also very polite and efficient.

Plantation shutters visited my flat 20 January 2022 to measure, discuss slat size and material, and give me a free estimate which I was happy with.
