- Insulation is measured by its thermal resistance. Contact the Energy Division’s Advisory Service for the appropriate insulation R-value for your area.
- Use door and window seals, gap filler or draught excluders to block draughts.
- Seal gaps around skirting boards, ceilings and old air vents.
- Well-designed eaves shade summer sun while allowing winter sun in. External blinds, pergola or deciduous vine can also be used.
- Heavy lined curtains and pelmets help keep heat in during winter and out on hot summer days. Pelmets stop draughts caused by airflow between curtains and windows.
