The heat loss from a dwelling can be divided into two main categories:
- Fabric heat loss - heat loss as it is transmitted through the fabric of the building.
- Ventilation heat loss - heat loss through ventilation or draughts.

Types of insulation
In order to save you money by reducing your energy and water costs whilst reducing your impact on the environment it is essential to ensure your home is adequately insulated.
Standards of insulation in new housing are considerably higher than they are in older housing. However, properties built before current standards make up by far the largest proportion of the UK housing stock. In order to improve energy efficiency, reduce heating and hot water costs and to reduce CO2 emissions the fitting of insulation into existing housing stock is essential.
The following are types of insulation:
- Hot water insulation
- Roof insulation
- Wall insulation - both cavity and solid wall
- Draught proofing
- Floor insulation
- Double and secondary glazing.
