While we are sure your ACT strata is already toasty warm, there is always room for a bit more heat indoors. However, it can often come at the expense (literally) of your power bill. One way of making sure your home stays warm without breaking the bank is by changing the curtains to a material a bit friendlier for winter.
But which materials make for the best curtains?
Keep them long
Across the pond, Consumer NZ recently ran a study on different types of curtains and how well they retained heat. One of the primary findings was that the longer curtains are, the better they will be at keeping you cosy.
Even thermal curtains that were only the length of the sill barely had more heat retention than a window with no covering at all. Meanwhile, floor-length thermals on their own performed slightly better, while adding polar fleece to them increased performance significantly.
Insulation still tops
Two of the three best results from the Consumer NZ study were double-sided polystyrene insulation and a secondary glazing kit for the glass. While effective, these might not be the most economic decision for your ACT strata.
Net curtains and custom heavy curtains also recorded solid performance for keeping the heat indoors. These results were for wooden frame windows as well. For aluminium frames, glazing and insulation knock thermal curtains with polar fleece out of the top two spots, while net curtains dropped to the bottom.
The key conclusion was that it doesn’t matter as much about how thick the material is – what is important is disruption of air flow. You may not be able to conduct large scale changes to your strata without owners’ corporation approval, but a quick fix on your curtains could stop heat from escaping on those cold nights!
