Khus Curtains :

Another way to reduce the heat that builds up due to convection is to use khus khus curtains. It is an age-old method to keep the houses cool naturally. The dried roots of vetiver or khus weaved together with coir and straw make for a curtain with an organic look and pleasant earthy aroma. Khus khus blinds have to be kept wet to bring down the indoor temperature. Khus curtains not only add to the aesthetics of the house but also keep it light and airy.
