Introduce baffles which inhibit the movement of air/water/whatever
Garments can be designed with a snug fit to minimize the air flow between the fabric and skin, thus reducing heat transfer by convection. Adding additional layers or insulation within the garment can also help to trap heat and reduce convective heat loss. Using materials that are less breathable can further inhibit airflow and heat loss through convection.
Cavity wall insulation helps to reduce heat loss through convection, which is the transfer of heat by moving air between the inner and outer walls of a building. This insulation fills the gap between the walls, creating a barrier that impedes the movement of air and therefore reduces heat loss through 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.
To reduce heat loss by convection, you can improve insulation in the space by sealing any gaps or cracks in walls, windows, and doors. Additionally, using draft stoppers and installing thermal curtains can help minimize air circulation that leads to heat loss. Lastly, adding carpeting or rugs to floors can create a barrier to prevent warm air from escaping through the floorboards.
Closed-cell foam insulation is one of the best thermal insulators to reduce heat transfer by convection. It has a closed structure that prevents air movement within the material, reducing convection currents and heat transfer. This type of insulation is commonly used in homes, refrigerators, and other applications where minimizing heat loss is important.

Thermos flasks primarily reduce heat transfer by conduction, convection, and radiation. The vacuum insulation between the inner and outer walls of the flask minimizes heat loss through conduction. The silvered coating on the inner surface reduces heat transfer by radiation, while the narrow neck minimizes heat loss through convection.
Loft insulation primarily reduces heat loss by conduction. It works by trapping air in the material, which slows down the transfer of heat through the building's ceiling. Some insulation materials may also help reduce heat loss through convection by preventing air movement within the insulation layer.
heat loss through air
Insulation materials reduce heat loss by trapping air pockets within their structure, which slows down the transfer of heat. This trapped air acts as a barrier, preventing heat from escaping through conduction, convection, and radiation. As a result, less energy is required to maintain a comfortable temperature in a building.
Foam reduces convection by trapping air pockets within its structure, which hinders the movement of air and creates a barrier to heat transfer. This lack of air movement limits the convection currents that would otherwise carry heat away from a surface, thereby reducing heat loss or gain.
Plastic foam reduces energy transfer by convection because it has a low thermal conductivity, which means it is not a good conductor of heat. This slows down the movement of heat through the material, making it harder for convection currents to form and transfer heat. As a result, the foam acts as an insulator, reducing heat loss or gain.
Fiberglass insulation traps pockets of air within its fibers, creating a barrier that slows the transfer of heat. This helps to reduce heat loss by limiting the movement of heat through conduction, convection, and radiation within a building's walls or ceiling.
