When temperatures drop, it may happen that, despite the heating at maximum, you continue to feel cold in the house. A good one thermal insulation is crucial to prevent heat loss, and windows they are often among the main culprits. Fortunately, there are several solutions to prevent heat from escaping.
Window insulation: how to save energy with 5 effective moves
Here are 5 effective methods to maintain thermal comfort in your home. By following these simple strategies, you can improve your home’s thermal insulation, reduce energy costs and create a more comfortable environment. Investing in energy efficiency is a choice that pays off over time, both in terms of economic savings and living comfort.
1. Choose double glazing: an essential investment
If you still have single pane windows, you are losing a significant amount of heat. Just touch the glass to realize it: the surface is as cold as the outside air. The transition to double glass represents a significant initial investment, but the benefits are considerable: you can save up to 40% on your energy bill. Furthermore, double glazing significantly reduces heat loss and increases home comfort.
Don’t have the budget for a complete replacement? You can opt for the installation of overlapping double glazinga less expensive solution that still improves the insulation of existing windows. Furthermore, if the window frame is made of wood, you could replace just the glass by installing double glazing without having to change the entire frame.
A study published in Applied Thermal Engineering highlights that the use of advanced insulation materials and optimized chassis design can significantly reduce the thermal bridgesthus improving the energy efficiency of buildings.
2. Check ventilation and ventilate every day
Excessively humid air requires more energy to be used to heat it, thus increasing bills. Modern homes are equipped with systems controlled mechanical ventilation (VMC) to renew the indoor air, but these require regular maintenance: clean them at least once a year. Furthermore, ventilate daily for about 10 minuteseven on the coldest days: this helps maintain a healthy, dry and comfortable environment.
3. Improve window joints
Air infiltrations can seriously compromise thermal insulation. If the joints are old, worn or missing, replace them with new ones in mousse or eraser for the moving parts. To fasten between the frame and the wall, use del putty or a acrylic joint. This intervention is cheap and easy to carry out, and can be performed without the help of a professional.
4. Use modern thermal roller shutters
If you plan to replace windows, also consider adding thermal roller shutterswhich can be both manual and motorized. These systems improve insulation by creating a barrier between the outside and the inside, thus reducing drafts. Unlike traditional wooden shutters, thermal roller shutters adhere almost completely to the window, increasing the comfort of the home.
5. Install insulating films and thermal curtains
For additional insulation, consider installing insulating films directly on the glass: these thin films retain heat during the winter and reduce the entry of sunlight in the summer. They are especially useful for older windows. In combination, you can use thermal curtains composed of insulating materials that add a barrier against the cold, further improving energy efficiency.
