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.

DOC is rolling out a new tool to help figure out what to tackle first when it comes to protecting our threatened species and the things putting them at risk.
Why does this matter? As Nikki Macdonald from The Post points out, we’re a country with around 4,400 threatened species. With limited time and funding, conservation has always meant making tough calls about what gets attention first.
For the first time, DOC has put real numbers around what it would take to do everything needed to properly safeguard our unique natural environment. The new BioInvest tool shows the scale of the challenge: 310,177 actions across 28,007 sites.
Now that we can see the full picture, it brings the big question into focus: how much do we, as Kiwis, truly value protecting nature — and what are we prepared to invest to make it happen?
We hope this brings a smile!
Poll: Are you still heading to your local for your caffeine fix, or has the $$ changed your habits? ☕
Wellington’s identity is built on its cafe culture, but with costs climbing, that culture is under pressure. We’ve seen the headlines about recent closures, and it’s a tough pill to swallow along with a $6+ coffee.
We all want our favourite spots to stay open, but we also have to balance our own budgets ⚖️
