The heatwave is back in full force this week, and homes are quickly taking on stifling warmth. So, before dreaming of air conditioning beyond your budget, a small Decathlon product could help soothe the heat.
When the heatwave hits the windows, the house heats up faster
Anyone who isn’t lucky enough to have air conditioning experiences the same thing during a heatwave. Shutters stay closed, windows open only at dawn and after nightfall, and the fan runs for hours… and yet the temperature climbs even higher. After last week’s dip, the heat is back in full force across a large part of the country.
On Wednesday July 8, Météo-France already shows 34 °C in Bordeaux, 36 °C in Nantes, 37 °C in Lyon and even 40 °C near Montpellier. In a south-facing apartment, a glazed bay or a window without a shutter can become the weak point of the room. It’s often there that the interior suffocates.
Decathlon hides a trick in its hiking gear section against the heatwave
The item in question isn’t anything close to a decorative accessory. It is the Decathlon single-use survival blanket, sold at €2.99. In its packet, it looks tiny. Once unfolded, it measures 160 x 210 cm and has two faces, one gold and the other silver.
Its merit lies precisely in this detail. According to the product directions, the gold side placed facing outward helps retain heat, while the silver side facing outward is used to stay cool, particularly in a car or a tent. At home, this second option can therefore become useful in front of an overly exposed window.

The heatwave is better managed with a well-thought-out installation
The idea isn’t to turn the living room into a cold bedroom. However, when placed with the silver side facing toward the sun, the blanket can help limit the furnace-like effect behind a window, especially during the hottest hours. You secure it neatly against the glass, with suitable tape or clamps depending on the configuration.
You must also follow the product’s precautions. The blanket must not cover the head, it should not be used near a heat source, and you must not cut it. But for less than €3, this Decathlon accessory can become a very practical interim solution during heatwaves, especially in homes that are difficult to cool.
