Investigating The Effectiveness of a Home - Insulation Method.

Introduction

Jill Heyes. 10H. Tuesday 11th December. 2001. Investigating The Effectiveness of a Home Insulation Method. Plan We are going to investigate the effectiveness of a home insulation method. Loft insulation. Double glazing. Cavity wall insulation Draught proofing. We have chosen to investigate the effectiveness of Loft insulation. Home heating costs money, not just to buy the heaters, but also to pay for the fuel that has been used. The amount of fuel we use as a nation each year to keep warm is equivalent to 30million tones of coal. Better insulation in our homes cuts down on fuel bills and could reduce the need for more power stations. Loft insulation is very cost effective. A home without loft insulation loses heat through the roof almost as quickly as if there wasn't a roof at all. There are various materials for loft insulation which all work on the principle that the best insulator is a layer of still air trapped just above the upper floor ceilings. Glass-fibre, mineral wool, expanded polystyrene, vermiculite and cork are all suitable. Loft insulating materials containing a high proportion of air trapped in little solid matter. ...read more.

Fire retardant sheets available. The disadvantage: It costs twice as much than glass fibre. Reflective Foil Building Paper. * Heat reflects off the shiny surface- back into the house in winter/or back into the loft in summer. Results 1st 2nd Average At room temp At 1 minute At 2 minute At 3 minute At 4 minute At 5 minute At 6 minute At 7 minute At 8 minute At 9 minute At 10 minute Method In this investigation I made a model house out of cardboard using plastic for the windows, which I attached with sellotape. First of all I took the room temperature using a thermometer and recorded it on to a table (as shown under RESULTS), I switched the light bulb on and recorded the temperature at intervals of one minute, over a period of ten minutes. The light was switched off and after waiting for a while I was ready to begin my next experiment. For this part I laid some insulation material on the top of my model house and carried out a similar test again. ...read more.

Conclusion

At three minutes my graph with loft insulation increased drastically against my graph without loft insulation. If more insulation was used on my model house the gradient would be much more steep. If I had used a different sized house e.g a larger one, the results would have been affected making the them different e.g lower. The results could have also been affected if a different sized or wattage light bulb had been used. To see a different table of results I could have repeated the experiment by using other types of insulators e.g loose fill or expanded polystyrene sheets. I could have also repeated the experiment by recording the temperature every 30 seconds instead of every minute to make the experiment more accurate. Evaluation I feel as though I completed the experiment fairly by looking at my results, they followed a pattern which increased continuously. The results were shown as reliable and a prediction could have been made to get further or more accurate results. My results support my original prediction, which was the temperature increased with loft insulation than without loft insulation over a period of time. I would like to carry out this same experiment using different loft insulators on a larger house and a smaller house, to see what results they would have. ...read more.

3 star(s)

Overall this is an interesting experiment and one that is very useful. The strength in this report is the information provided. However, including more analysis and interpreting the results found would have made it better. ***
