the insulation is most often due to the air space between the skin and the cloth.
different textiles are able to maximize this insulation by trapping more air for longer.
wet suits use the same principle with water.
the body heats the particles that are trapped between the skin and the cloth just like animals do with there fur. the thicker and denser the cloth the less the heat will transfer

Why does opaque clothing reduce the transfer of heat by radiation?
it reduces the amount lost through holes in the clothing.
How can heat transfer in liquids and gases be reduced?
Insulation will reduce heat transfer.
How does fleece reduce heat transfer by conduction and convection?
it reflects the heat back
What can slow the movement of heat energy from a warmer object to a cooler object?
Transfer of heat can be slow down by increase insulation. For radiation heat transfer, colour coating could reduce rate of radiation in the same manner as insulation. Reduce surface area of heat transfer (or area of contact) can also reduce rate of heat transfer.
How does a thermos reduce heat transfer using convection?
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other.

Why does closing windows reduce heat transfer?
because it doesnt allow heat to get inside or outside, depending on the season
How does a vacuum bottle keep food hot or cold?
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
Which type of heat transfer does an oven mitt reduce?
An oven mitt reduces heat transfer through conduction. Because oven mitts are usually made of materials that are poor conductors of heat, the transfer of heat from the hot object to your hand is reduced when wearing them.
What is the energy transfer when you iron some damp clothing?
Electrical energy into heat energy
Is cloth a good conductor of heat?
Most clothing is not a good conductor of heat, because one of the purposes of clothing is to reduce the energy input required maintain the human body at a constant temperature. Clothing that is a good conductor of heat would frustrate this purpose.
What kind of heat transfer is a marshmallow over a bonfire?
A marshmallow over a bonfire is a radiant heat transfer. The marshmallows are not in direct contact with the flame but are held very close to reduce burning.
How do opaque objects reduce the transfer of heat by radiation?
because black things absorb more heat and white things reflect it
