Aren't you tired of sky-high winter power bills? Start with your windows to stop the cold from getting in. Based on ABS data, electricity prices in Australia rose by 21.5% in the 12 months to December 2025. That's sobering stuff.
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.
The numbers don’t lie
Up to 40% of your home’s heating energy can escape through windows. The good news? Properly fitted curtains and blinds can cut heat loss through single glazed windows by 60%.

1. Thermacell blinds (also known as honeycomb blinds)
Thermacell blinds are one of the most energy-efficient options you can install. Their clever honeycomb structure traps air in little pockets between the blind and window glass, creating a barrier that slows warm air escaping. In fact, a tight fit can cut up to 60% of heat loss through windows, which could save you up to 10% on heating energy bills.
Pro tip: If you already have Thermacell blinds, check they fit snugly with no gaps. Even a small draft can reduce their efficiency

Heavy curtains with thermal lining
Not all curtains are created equal. The thickness, length, fabric and lining all matter. Curtains with thermal or blockout linings help prevent warmth from escaping through the glass. When drawn by sunset and long enough to touch the floor, these curtains create a pocket of warm air inside.
Mid-coloured curtains with white linings are especially effective and have been shown to reduce heat loss by up to 33% in some studies.
If you’ve already got new curtains, here’s some pro tips to keep the warmth in:
- Draw them just before sundown
- Make sure they sit close to the window frame
- Avoid gaps at the top, sides, and bottom where heat can sneak out
Double up: curtains and blinds
Layering is a smart way to boost insulation. Try pairing Thermacell or roller blinds with curtains for a stylish look that keeps heat in. Each layer adds another line of defence between your home and the chilly outside air.
This combo not only looks great but gives you flexibility throughout the year - open the curtains and keep the blinds down to enjoy filtered sunlight without losing heat.

Soluna Roller Blinds: sleek insulation for modern homes
Soluna Roller Blinds come in a wide range of colours and natural fabrics, perfect for modern, eco-conscious homes. With options like motorisation and dual blind systems, they combine style and functionality.
