Sheer curtains are best for filtering light and maintaining privacy, so they're obviously a great spring and summer window treatment solution. But winter isn't all dark and it's worth making the most of the light on shorter days. In fact, letting sunlight shine in through the windows is a key source of natural warmth in winter. So here's how you can use sheer curtains AND insulate your windows.
The thermal curtains that sit behind the sheers would be closed at night for insulation and opened during the day with the sheer at the front filtering the light. We fitted an example just like this which you can see in Shayden's episode of our People & Homes series. On the back track is a James Dunlop fabric that can be used as a curtain or lining; over the top of that, on the front track, is a blended sheer fabric. Alternatively, you could have them the other way around - a thermal in front and sheer curtain behind.
Sheer curtains over blockout honeycomb blinds fitted inside the window frame
Honeycomb blinds are also known as 'cellular shades' or 'designers' double glazing'. Consumer NZ found that of all window coverings, thermal lined honeycomb blinds retain the most heat (at around 60%). This is because their cells trap a pocket of air that acts as a barrier, allowing them to regulate the temperature of any space and help keep your home warm. The idea here would be to fit the honeycomb blind inside the window frame (so the sheer can go in front), draw it down at night for insulation, then when it's up, the sheer curtain remains in place to diffuse the light and create a cosy daytime atmosphere.
What about a sheer curtain over a thermal roman blind?
Yes, this would work similarly to the honeycomb blind. But the thing to consider is that a roman blind stacks at the top when drawn open/up and that takes up some of the window and therefore blocks the light. It would be better on a very large window. By comparison, a honeycomb is slimline and when up takes up very little space at all.
A few more tips and tricks
- The trick to retaining all that good warmth the sun has brought in during the day is to close the thermal curtains or blinds as the light begins to fade so the heat doesn't escape through the window glass.
- What's essential for good insulation at the windows is a pelmet above the curtain rail. This helps create a pocket of air (similar to how double-glazing works), which helps to reduce heat loss.
