Insulation reduces heat loss by replacing air space with a less conductive material (insulation). Therefore the answer is conduction.

Does solid wall insulation reduce conduction convection or radiation?
All three methods. Any non-translucent material (like a wall) stops radiation, the fact air can't go through the wall stops convection, and the air that's trapped in the cavity/in the material itself (the air is the actual insulation, the "physical" part of insulation is simply designed to hold a lot of air stationary) stops conduction.
How does foam wrap reduce radiation and conduction?
Foam wrap can reduce radiation and conduction because it is not a very good heat conductor.
How does a thermos flask reduce heat loss by convection?
A vacuum between two glass sheets will greatly reduce heat loss through convection, and also through conduction. The fact that the glass is coated (to convert it to a mirror) also reduces the loss by radiation.
How does fleece reduce heat transfer by conduction and convection?
it reflects the heat back
Is a heater a conduction or convection?
Heater Is neither Conduction nor Convection... The Questions seems to be wrong... If you ask Whether the heat given by a heater is lost by conduction or Convection, then the answer is: YES! In a heater the heat is lost by all three processes namely Conduction , Convection and Radiation.
Does closing a door at home on a cold night reduce convection radiation or conduction?

How cavity wall insulation helps to reduce heat loss?
A major part of the heat transfer through a cavity wall lacking insulation is convection - and to a lesser degree radiation. When insulation is placed in the cavity between the walls it significantly reduces both convection (air doesn't move well through insulation like it does in empty space) and radition (the walls can't "see" each other through the insulation). For the insulation to be effective, the thermal conductivity of the material must be low enough that conduction through the insulation is much less than was present with convection.

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 thermal energy transfer does a foil wrapping reduce the most?
Conduction (Apex)
How does conduction and convection and radiation relate to the law of conservation of energy?
Heat energy is transferred from one place to another; no energy is created or destroyed. It is possible for heat energy to be produced or absorbed (this has nothing to do with conduction, convection, or radiation); however, total energy is still conserved. For example, the heat energy produced will reduce the amount of some other type of energy.
Does Floor Insulation reduce conduction convection or Radiation?
Consider for a moment how each form of heat energy is transmitted.Conduction requires contact, physical connection between the heat source and the conducting material and the receiver. A conventional electric stove element is a good example of this. As the floor is not floating in air, some conduction of heat does occur, it is difficult to insulate from completely, but the transfer is negligible.Convection is the transfer of heat via a fluid matrix. Think air conditioner coil here. Another example of convection transfer is seen in a convection oven where the fluid matrix is heated air.Radiation is the transfer of any form of energy by excitation of atoms or molecules. A microwave or the infrared heat energy of the sun are good examples of this. However, occasionally radiation doesn't need medium for transfer.In many case heat is transferred through combinations of two or even the three heat transfer modes: conduction, convection, and radiation.Homes are insulated to prevent conduction of heat or cold by contact with heated or cooled air.
