Cavity walls & insulation Initial cost: £150 Annual saving: £100 Lagging such as fibre glass wool reduces conduction. Cavity walls & insulation Initial cost: £150 Annual saving: £100 Lagging such as fibre glass wool reduces conduction. Draught proofing Initial cost: £100 Annual saving: £15 Fibreglass ‘wool’ laid across the loft floor reduces conduction through the ceiling into the roof space. Draught proofing Initial cost: £100 Annual saving: £15 Fibreglass ‘wool’ laid across the loft floor reduces conduction through the ceiling into the roof space. Double glazing Initial cost: £2400 Annual saving: £80 Two layers of brick with a gap between them reduce conduction. Insulating foam squirted into the gap between layers, trapping pockets of air to minimise convection.
