Electrical insulation:
An electrical appliance which is double insulated does not have an earth wire fitted. The appliance is designed in such a way that the electrical parts can never come into contact with the outer casing of the device. Common double insulated appliances are hair dryers, radios and cassette players.

What is critical radius of insulation?
The critical radius of insulation is a counterintuitive concept within the study of heat transfer.
How much energy does insulation save?
it depends on the r-value of the insulation and the area or temperature range of the climate it is to be installed
Is r-value good or bad?
it is a good thing i think R Value is the thermal resistance of a given material. The higher the R Value the more thermal resistance and the better the insulation. So, an R48 roof system is warmer than an R32 roof system. All insulation materials are rated by their R Value. An inch of rigid insulation has a higher R Value than an inch of fiberglass insulation. Check with the insulation manufacturer for the R Value.

What is the purpose of a double glazed door?
A double glazed door would provide additional insulation and protect against heat loss. Double glazed doors consist of two panes of glass with a space between them that provides insulation.

How does double insulation protect users from electric shock?
Double insulation is a safety feature in electrical appliances where an extra layer of insulation is provided between the conductive parts and the exterior surface. This prevents direct contact between the user and any conductive parts that may become live due to a fault. If a fault occurs and the live parts touch the conductive parts, the double insulation ensures that the user is protected from electric shock by preventing the flow of electricity to the exterior surface of the appliance.

What is meant by the sentence the hair dryer has double insulation?
The statement "the hair dryer has double insulation" means that the hair dryer is designed with an extra layer of insulation to protect against electric shocks. This additional layer provides an added safety measure by reducing the risk of electrical hazards.
What are used to help conserve heat in houses?
Loft insulation and double glazing.
What is the U value of a double pane window?
The U value of a double pane window is a measure of its insulation ability. It represents the rate of heat transfer through the window, with lower U values indicating better insulation.
What is the increased percentage of insulation with double glazed windows as opposed to single glazed?
The percentage insulation witha double glazed window, as oppsoed to a single glazed window is about twenty three percent less. This makes it very energy efficient.
If an appliance has only two pins what must the appliance have to prevent us from electrocution?

Why is air between a window important?
The air in a double pane window is insulation from cold weather.
