Heating: here’s how to know if your accommodation loses heat unnecessarily

Tip, as effective as unknownidentifies thermal leaks without expensive equipment or expertise in insulation. A quick testaccessible to everyone … and which may well reserve surprises in store for you. So how do you know if your interior is a real energy gruyère? The answer may well surprise you.

Why does your accommodation lose heat?

Thermal losses are a scourge For many homes. A heating that runs continuously without offering real comfort is often a sign of poor insulation. On average, an ill -insulated house can lose up to 30 % heat by the roof, 20 % per walls and 15 % by windows. These losses are often invisible to the naked eyebut they translate into excessive consumption and persistent thermal discomfort.

The main causes of these energy leaks are:

• Poorly insulated windows : worn joints or a defective installation let the air infiltrate.
• Doors leaving air currents : space under the door or around the frame is a privileged passage for the cold.
• A badly isolated roof : The heat rises and easily escapes by a non -waterproof roof.
• Walls without insulation : especially in old housing, walls can act like thermal bridges.

Fortunately, there is a simple and easy way to find out if your home suffers from these energy losses.

The paper sheet test: a simple and effective method

Far from sophisticated equipment like thermal cameras, this test uses an object that everyone has at home: a simple sheet of paper. Here’s how to proceed:

• Place a sheet between the opening and the frame of a door or a window.
• Close the opening normally, without forcing.
• Try to remove the sheet:
  If it resists And stay stuck, your insulation is correct.
  If it slides easily or fallsthis means that air passes and the heat escapes.

This test must be carried out on several windows and doors To have an overview of the weaknesses of your accommodation. Remember to also test the space under your outer doors: if a sheet of paper slips there without resistance, it is a sign of significant air current.

How to limit these heat losses without breaking the bank?

If your test reveals leaks, there are several solutions adapted to all budgets To improve insulation and reduce your energy consumption.

1. Check and strengthen the joints : Mock windows and doors are often involved. Investing in foam or rubber adhesive seals allows you to block air infiltrations quickly and efficiently. These products, available in DIY stores, are easy to install and inexpensive.
2. Use door sausages : A space under the door lets out a lot of warmth. Door sausages are a simple solution to install and can drop your heating consumption by preventing cold air from entering.
3. Install thermal curtainsS: Windows are one of the main points of energy loss. Installing thick and thermal curtains limit the feeling of cold and improving comfort in winter.
4. Place an overlapping or insulating films : If you cannot change your windows, insulating films or survival can improve their thermal performance without requiring major work.
5. Check the roof and wall insulation : If your budget allows, strengthen the insulation of the attic or the walls offers spectacular results on your comfort and your heating bills.

Thanks to these tips, you can limit your heat losses and make significant savings on your energy bill. A simple test with a sheet of paper can therefore be the first step towards a more economical and comfortable accommodation.
