Window treatments to keep your home warm this winter
Aren't you tired of sky-high winter power bills? Start with your windows to stop the cold from getting in.
BRANZ, an independent research organisation, says:
• 42% to 45% of heat in houses insulated to Pre-2007 requirements is lost through windows.
• If your home has been built or renovated under the 2007 Building Code, which requires double glazing, you still lose up to 31% of heat through windows.
• Properly fitted curtains and blinds can cut heat loss through single glazed windows by 60% and double glazed windows by 40-50%.
Choosing the right window treatments will help insulate windows and prevent heat loss. Here are three options to answer your "how can I warm up my home?" this winter.
Honeycomb Blinds
Honeycomb blinds are one of the most energy-efficient window treatments. They are also known as honeycomb or cellular shades. These window coverings feature a honeycomb structure to make an air pocket between the window glass and the room that acts as an insulator, blocking heat and keeping the cold out.
When a heater is running, Honeycomb blinds reduce heat loss through windows by up to 60%, which equals around 10% savings on your heating energy. In hotter months, honeycomb blinds reduce unwanted heat from the sun through windows by up to 60% when installed with a tight fit. They are available in different layering options, including single and double-cell.
Heavy curtains or drapes
Drapes or curtains are another way to insulate your home by adding one extra barrier against the cold winter air. The main difference is that curtains are sized to fit the window, and drapes reach the floor.

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!
