**__ Research __** __ Double paned __ windows prevent window drafts. __ Rigid insulation __ is made plastic foams produced in board-like forms. These provide full coverage with few heat loss paths. Rigid insulation is often used for foundations and as an insulative wall covering. __ Blown-in loose-fill __ is a form of insulation that is used in wall cavities. It is appropriate for unfinished attic floors, for irregularly shaped areas, and for filling in around obstructions. http://www.ehow.com/how_2151838_insulate-windows-inside.html http://www.ornl.gov/sci/roofs+walls/insulation/ins_02.html **__The Experiment__** **__Materials:__** · Card box · Polyethylene bubbles · Modelling clay/ plasticine · Tape · Clear plastic 1. A piece of card box was cut up according to the diagram below:
 * Sources: **
 * __Construction:__**



2. The Polyethylene bubbles were stuck to each of the walls, using double sided tape, including on what was to be the ceiling and the roof. The polyethylene bubbles were to act as the //rigid insulation// that I found in my research.



3. There were five windows on which the clear plastic was applied. There was a layer of the plastic on both sides of the cardboard to create the same effect as a double paned window.

4. The house was stuck together using tape on the outside and in the inside the modelling clay was put on the edges of the house where the walls met. The modelling clay was to play the same role as // blown-in loose-fill //. The modelling clay was supposed to fill in any cavities that were in the edges of the walls.

1. The house was tested outdoors along with another control house.
 * __ Testing procedure __**

2. There was a temperature check every 10 minutes on the houses using a thermometer inserted through the top of the houses.



3. There were a total of 7 checks including the initial temperature check before the house models were put outdoors.
