Whilst you may have installed excellent insulation and energy efficient heating systems – much of the benefits may be lost unless you pay particular attention to sealing potential air leakage cracks and gaps in such places as:
• around service penetrations (e.g. pipe work and cabling) including those enclosed or boxed-in
• behind fitted units, bath and shower tray panels, toilet units
• at the junctions of external walls and floors, including skirting boards
• around windows and doors, generally at the junction of the frame and the recess
• electricity socket points and light fittings
