Draught-proofing strips, brushes and covers seal the gaps around doors, windows, letterboxes and floors. It's often the cheapest, fastest win for an older or draughty home.
Why draught proofing matter
Uncontrolled draughts force your heating to work harder. A few pounds of sealing kit can noticeably improve comfort and cut heat loss — usually paying for itself in a single winter.

Read ReviewBuying advice
Target the obvious gaps first
External doors, sash windows and letterboxes leak the most — fix those before chasing small gaps.
Don't block essential ventilation
Never seal air bricks, extractor vents or rooms with open-flue appliances.
Choose the right profile
Measure gap widths so the strip compresses properly — too thin does nothing, too thick stops doors closing.
