Do Thermal Curtains Really Work?
Curtains, particularly thermal lined ones, can reduce heat loss by as much as 60%, depending on the type of windows your home is fitted with. The key to ensuring you get the most out of your curtains is in understanding exactly how heat is lost, and how the use of thermal lined curtains can prevent this.
Understanding the physics: You know the old saying that hot air rises? Well, during cold weather that is exactly what happens, and something called the reverse chimney effect comes into play.
It is widely accepted that cold air is denser, and therefore heavier, than warm air. When it’s cold outside the air close to the window is cooled and sinks down (due to its density increasing with the temperature change). When the cooled air sinks it’s replaced by warmer air from other parts of the room.
As you can imagine, this then creates a circulating current, taking all of your warm air and replacing it with cool air. And just like that, you have lost most of your heat, not just near the window, but in the entire room.
If your curtains are not fitted correctly they form a channel between the window and the curtain, creating a space for the cooled air to sit and increasing the effect of the reverse chimney. The most important aspect to note is that it is the power of each factor combined, which decreases heat loss. No single factor works in isolation.
The first thing to ensure is that your curtains fit your windows correctly. This means that they are within a millimetre of perfect, with absolutely no gaps at the top or bottom. They need to fit against the wall snugly, creating a seal between the curtain and window.

Mr Minit in Chartwell: Be wary
Hi all,
Just sharing my experience. I had the battery for my car key replaced in March 2025 at Mr. Minit in Chartwell. I was given a one‑year warranty, which seemed impressive at the time.
However, the battery stopped working early Mar 26. With the warranty card, I brought the key back to have it checked and replaced. What I didn’t realise was that the battery was *not* actually replaced. He only tested it with a meter. When I asked whether he had replaced the battery, he said “yes,” but that wasn’t true. He then said he had tested the battery level and there was no need to replace it. When I asked to see the meter, it showed the battery was in the green zone which means it was ok.
I was then advised that I might need to replace the entire key unit. I asked whether he had properly troubleshot the issue to confirm it was the battery and not the key itself. His reply was that he normally doesn’t do that, but I was a “special case.” That means, the warranty card was a misrepresentation and there was no real intention of replacing the battery when it was faulty.
After he finally replaced the battery with a new one, my key worked perfectly again.
**Lesson learned:**
Make sure you take a photo of your warranty card. I feel like the warranty is mostly for show — if I had lost it, I would have been charged another $20+ for a battery. Worst still, I would have to pay more to change the key unit unnecessarily.
Make sure you witness that they replace your old battery with a new one if it's still under warranty.

Whether it’s a courgette takeover or a feijoa frenzy, don’t let those garden gems go to waste!
Our suggestion to you: Did you know you can grate and freeze excess courgettes to use in chocolate cake later? It sounds a bit dodgy, but it makes the cake incredibly moist ... and hey, it counts as a serving of veg, right? 🍫
