Dear friends, 
Did you know that 20 to 50% of all the energy that is used to heat up a typical home during the winter is lost through its windows? This wasted energy increases our heating bills as well as our carbon footprint, neither of which does anyone any good. With this in mind, we have designed the Kume curtain: a simple and inexpensive home-made insulating curtain that can help us save money, keep our homes cozier and be kinder to the environment. 
"Kume" in Mapudungun, the language of the Mapuche people of Chile, means "good." We feel that this name is well-deserved as the performance of these curtains is very "kume" indeed.
The following photographs speak for themselves.

They were taken early one winter morning and clearly show that the window fitted with a Kume curtain is much cooler than the one fitted with a conventional decorative curtain - and is actually even cooler than the masonry wall. This can mean only one thing: instead of letting the heat seep out of the house, the Kume curtain keeps the heat in, where you need it.
