Energy Transfer

Use Draught Proofing to Reduce Heat Loss in Buildings.

All of the insulation methods in buildings that we have
looked at so far use trapped air to reduce conduction.

The air within the rooms in buildings will transfer heat
to the outside by convection.
This happens particularly where warm air leaves a building
through gaps around doors and windows.
These gaps can be sealed by using draught proofing.

Draught proofing involves using plastic strips or foam
around the edges of doors and windows
to seal any gaps when the door or window is closed.
This reduces heat loss by convection.
The room in the house stays warmer for longer (see costs).
