1. Heat measurements A few weeks ago we made some measurements on types of insulation A few weeks ago we made some measurements on types of insulation We had chosen 2 types of insulation to experiment with. One of them is polyester insulation and the other one is a “Romanian” made insulation, an ecological one, made from sawdust, glue, paper, water, and we covered it in recycled news-papers.

2. The first one In the first experiment we let the “house”, made from a postal-box, not insulated and put an electrical resistance inside.In the first experiment we let the “house”, made from a postal-box, not insulated and put an electrical resistance inside. We raised the temperature up to 60˚C and then we stopped the heating process.We raised the temperature up to 60˚C and then we stopped the heating process. We made a table and measured from 5 to 5 minutes during 25 minutes how much the temperature had dropped.We made a table and measured from 5 to 5 minutes during 25 minutes how much the temperature had dropped.

5. The second one : In the second experiment we insulated the “house” with polyester pieces and repeated the heating process. And we measured the cooling process again from 5 to 5 minutesIn the second experiment we insulated the “house” with polyester pieces and repeated the heating process. And we measured the cooling process again from 5 to 5 minutes

9. The third one: In the third experiment we insulated the “house” with “Romanian” made insulation, an ecological one, made from sawdust, glue, paper, water, and we covered it in recycled news-papers and repeated the heating process.
