We have recently lined the existing curtains in our house with new woollen blankets from the army surplus shop. The blankets are folded double and stitched together making an open ended bag which is then attached to the curtain at the top so that the completed article consists of three layers, being the original curtain and two thicknesses of woollen blanket. This has increased the average temperature in the house appreciably by reducing the heat loss through the glass. We believe this to be far more cost effective than double glazing. Our only heating is wood fires. We got enough blankets to do the whole of a three bedroom house plus a sleep-out for $500 from the retail store of kiwidisposals.co.nz in Christchurch. Their range of stock varies but it’s always worth a look. I believe they also have a store in Auckland.
