Double glazing, Gas is trapped between two layers of the glass which reduces conduction. The gas cannot circulate therefore reduces convection., Curtains, The movement of warm air from the room to the window is reduced which means there is less convection., Carpets, The material has air trapped between the fibres which reduces conduction., Loft insulation, The fibres of the material trap air which reduces conduction. This keeps this part of the house cooler as convection means it would normally get very warm., Cavity wall insulation, The material contains pockets of trapped air which reduces conduction out of the building., Silver foil, It reflects infrared radiation back into the building., Draught excluder, It reduces warm air that leaves the house through gaps. This reduces convection.
