During the winter, home heating is one of the main culprits in increasing bills. However, there is a simple, often underestimated gesture that can help reduce heat loss and optimize energy consumption: close shutters and roller shutters at night. It not only improves living comfort, but also translates into economic savings.
The effectiveness of this practice is confirmed by a scientific study conducted in Abu Dhabi which highlights its benefits, which are also adaptable to our winter climate.
Shutters and shutters: their insulating function against the cold
Windows represent one of the most vulnerable points of a building in terms of heat loss. Although many modern buildings are equipped with double or triple glazing, a significant percentage of internal heat continues to escape through these surfaces. This is where shutters and shutters come into play: by closing them, you create a additional barrier which limits the heat exchange between the inside and the outside.
A study conducted in Abu Dhabi, entitled “Thermal Performance Evaluation of Window Shutters for Residential Buildings”demonstrated that the use of shutters can significantly improve the thermal performance of buildings. Even though the study was carried out in a hot climate context, where the main objective was to protect environments from overheating, the principles applied are universal. Shutters and roller shutters work like a passive insulatorretaining heat inside during the winter and limiting heat loss.
How to close shutters and roller shutters helps you save money
According to the study, using closed shutters during critical hours dramatically reduces heat transfer through windows. This effect can be used in winter to maintain internal heat, thus helping to reduce the need to use heating at high temperatures.
Closing shutters and shutters creates an air gap between the glass and the external barrier, which acts like an insulating cushion. This is particularly important at night, when outside temperatures drop more and the risk of heat loss increases. The energy saved thanks to this practice translates not only into economic savings, but also into a significant contribution to the reduction of CO₂ emissions, making homes more sustainable.
The advantages for Italian homes
In Italy, where the winter climate varies from region to region, the effectiveness of shutters and shutters is particularly evident. In urban centres, for example, closing roller shutters or shutters also helps to shield the home from noise and light pollution, improving the quality of sleep. In colder areas, however, this practice becomes essential to retain the heat generated by heating systems.
Homes with dated or single-glazed windows benefit even more from this solution. When combined with heavy or thermal curtains, which add an extra layer of insulation, the improvement in thermal performance can be dramatic. Even those who own modern double or triple glazed windows can benefit from this simple daily habit.
Other measures to improve thermal insulation
In addition to closing shutters and shutters, there are other small measures that can help you keep your home warm in winter:
- Use thermal curtains: They add an extra layer of insulation and help block cold air from windows.
- Seal doors and windows: Check that there are no drafts and use insulating gaskets to improve the seal.
- Avoid covering radiators: Do not place curtains or furniture in front of radiators, so the heat can spread freely.
- Use reflective panels behind radiators: They help reduce heat dispersion towards the external walls, reflecting it inside.
Which materials to choose for shutters and shutters
If you are thinking of replacing or buying new shutters or shutters, pay attention to the materials. PVC shutters, for example, offer excellent insulating capacity compared to wooden or metal ones. For electric shutters, make sure that the box is well insulated, to avoid unnecessary dispersions.
It is also useful to consider the climatic context and the exposure of your home: for example, in particularly windy areas or areas subject to strong temperature changes, resistant and high-performance materials can make the difference. Finally, correct maintenance is essential to ensure maximum effectiveness: check regularly that there are no cracks or damage that could compromise the insulation.
A simple gesture for great results
Closing shutters and shutters at night is a simple gesture, but one that can have a significant impact on your heating bills and the comfort of your home. The study conducted in Abu Dhabi confirms that window closures improve the thermal performance of buildings, a principle also valid for the Italian winter climate. By integrating this practice with other measures, you can optimize your home’s energy consumption and contribute to environmental sustainability.
