How this tool works

A prioritised list of observations, not a heat-loss survey or a dollar-saving estimate. Keep required vents, flues and combustion-air openings clear. Do not enter a roof space, cover electrical equipment or seal a working fireplace. Ask an appropriate professional about gas appliances, dampness, condensation and ventilation. Renters should agree changes with the owner.

Ceiling insulation keeps warmth in the room below. Manage draughts where cold air gets in, but keep required vents clear.

Keep the warmth. Manage the air.

  2. Warm room
  3. Manage draughts
  4. Keep required vents clear
A conceptual building envelope: insulation slows heat flow; suitable seals reduce unwanted draughts. Required ventilation and combustion-air openings must stay clear. Use qualified help for roof-space work.
