Draughts are caused by unwanted cold air sneaking into your home through small gaps around windows, doors, floorboards, and even through keyholes and letterboxes – this is ‘unintended’ ventilation.

Draught proofing is one of the most simple, effective and affordable ways to start upgrading your home for comfort, energy efficiency and lower fuel bills.

It’s a straightforward first step that can deliver immediate comfort benefits, a cut in heat loss, and provides a logical starting point to preparing your home for deeper retrofit improvements down the line.
