Insulation is a material that has lots of pockets of trapped air. Air is a good insulator without loft insulation the roof space is full of air so why does that not keep temperature stable?
The insulation is a better insulator than air is. Pockets are there to allow 'slow' airflow so the house breathes and keep the insulation from molding.Also the air only acts as an insulator if it is trapped. If free it moves around and loses it insulating ability. Air in your attic (loft) Does act like insulation, but a very poor one.The same principle is in your double pane storm windows. if one of the panes crack, or breaks, the insulating value of the window falls.
How does insulation keep a home warm?
Insulation can help keep a warm house warm or a cool house cool. It reduces the transfer of heat by conduction, so warm air stays warm, and cool air stays cool. Insulation is a material that is a poor conductor of heat, usually because of pockets of trapped air.
What is a better insulator paper or foam?
Foam is a better insulator because of all the air pockets it has.
How are thermal insulator used to control the transfer of thermal energy?
Manufactures usually make building insulation from a fluffy material, such as fiberglass,that contains pockets of trapped air.
Is sponge a good heat insulator?
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
Why are potholders good insulation?
Air pockets hold heat, so they probably have a lot of them.

Why is air good insulation?
Air is not a good conductor of heat because it, being a gas with only a few particles in a big space, cannot store much energy by volume as it doesn't have much material in which to store the energy. However, air can move heat by convection, which means by moving and circulating it can transport the heat from one place to another. Because air moves with very little resistance it can easily move a lot of heat this way. So air is good insulation only if it is in very small pockets where the air cannot circulate easily. A lot of insulators actually trap tiny pockets of air to create insulation, such as foam or even fine knitted clothing.
How does an egg decompose?
eggs have little air pockets that make it stay good when the air pockets loose air it starts to rot
What is air good for?
for thermal insulation
What is hollow masonry used for?
Hollow masonry is used in various places on a building. Its main purpose is to insulate, the hollow blocks form a layer of air in the center promoting proper insulation. This can be compared to the air pockets in styrofoam insulation.

What are the key materials in Primaloft?
The key materials in Primaloft insulation are ultra fine synthetic fibers which trap tiny pockets of air to create an effective layer of air shielding the wearer from the cold.
