We all know that feeling… you finally get warm, then a sneaky draft from the window sends a chill through the room. Sound familiar? Luckily, your choice of curtains and blinds can make a huge difference in keeping your home cosy and cutting back your power bill.
The numbers don’t lie - up to 45% of your home’s heat can escape through windows
According to BRANZ (NZ’s building research experts), up to 45% of your home’s heat can escape through windows if your house was built before 2007. Even newer homes with double glazing can lose up to 31%! The good news? Well-fitted window treatments can reduce that heat loss by as much as 60%.
If you want to feel the difference this winter, here are three ways to warm up your home with smart window treatment choices.
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.
For better comfort in winter, choose blockout fabrics to help reduce heat escaping through your windows. Pair with Light Guard 360 for a snug fit that blocks light and draughts around the edges.
