How does the thickness of he loft insulation affect heat loss?
The answer is that the thicker the loft insulation is the more heat loss will be reduced as if it is thicker the more air is trapped between the layers of insulation and thermal energy cannot pass throught trapped air causing it to not leave your howm and therfore hating it Hope this helps C.Turner
What emerging technologies will make nuclear energy safer or more useable or more efficient or cleaner etc?
phillies
What is the physics behind loft insulation?
Insulation impedes the flow of energy. In the case of insulating a loft, this energy is in the form of heat. In the winter, when the inside of the house is warm and outside is cold, the insulation makes it more difficult for heat to escape through the roof. In the summer, the insulation keeps the heat outside the house. The rate of that increased difficulty is called an R-factor, such as R-30 or R-60. The higher the R-factor, the better insulated a house will be. Up to 25% of heat loss in a house occurs through the roof, so in theory, a well insulated loft could reduce heating and cooling bills by 20-25%.
How are solar cells of today superior to solar cells of the 1980s?
Advances in technology - coupled with the discovery of more efficient materials, make today's solar cells much more efficient than earlier models.

Will putting new windows in my home make my house more energy efficient?
Putting new windows in the home will not make the house more energy efficient. There would have to be a specific type of glass in the window.
Why apply insulation foam?
To improve insulation against heat or cold. Insulating foam is more efficient than fibreglass batts.
How can I make my home more energy efficient?
EnergySavers.gov has a great list of things you can do to improve energy efficiency. A few of the best ideas are adding insulation, a programmable thermostat, and using energy efficient appliances.
Do you think a shingled roof or a metal roof would be more energy efficient?
Shingles are more energy efficient than metal roofing. Metal roofing has no insulating properties so you would need extra insulation to make up for it. Plus they get hotter in the Summer.
What are the main benefits of house insulation?
House insulation gives the house a more comfortable temperature, reduces noise levels from outside the home, and reduces the costs of heating or air conditioning.
What can the combination of the single glazing and no roof insulation tell pupils that this is relevant to their investigation?
This is an older home.
What will not make fossil fuels last longer Improving heat insulation in the home Driving bigger cars Using more public transport Developing more efficient car engines?
using public transport
How do I remodel my house to be energy efficient?
To remodel your house to make it more energy efficient, in order to cut down on some electricity bills is a good idea. Some of the energies that you can move onto is Solar panels and wind energy.
Are upright freezers more energy efficient than regular freezers?
chest freezers are more energy and money efficient,but if you have the money upright freezers are far more convenient. chest freezers provide more insulation therefore saving money.
How does insulation of a nerve benefits the functionality of the nervous system?
Insulation of a nerve helps conduct the electric signal through it faster as the signal jumps from node to node along an axon and bypasses the insulation part (Schwann cells). So nerve insulation makes our nervous system more efficient.
How do you find out how much insulation is needed for house that is 8 feet tall and is 24 feet x 24 feet?
The answer will depend on where the house will be build: the amount of insulation required above the Arctic circle, for example, will be greater than that required in a more temperate region.The answer will depend on where the house will be build: the amount of insulation required above the Arctic circle, for example, will be greater than that required in a more temperate region.The answer will depend on where the house will be build: the amount of insulation required above the Arctic circle, for example, will be greater than that required in a more temperate region.The answer will depend on where the house will be build: the amount of insulation required above the Arctic circle, for example, will be greater than that required in a more temperate region.
