A Dubasari resident has collected 2,000 plastic bottles from all over the town and used them to thermally isolate the roof, floor and basement of the house where he lives, Info-Prim Neo’s correspondent in Transnistria reports. The man placed the bottles in rows and covered them with different rubbish – old cloths, paper pack. Then he wrapped them in plastic and put a thin layer of cement and sand on the top. As a result, the basement became dry. There was warmer during the winter and cooler in summer. The heating expenses decreased 1.5 times. The inventor is ready to offer advice to anyone interested.
