How to Draught Proof Your Home

Draught-proofing your home is one of the simplest yet most effective steps you can take to save energy, reduce bills, and increase indoor comfort. As colder months approach, ensuring your home is insulated against unwelcome breezes can make a remarkable difference. Here’s a detailed guide on how to draught-proof your home for greater warmth and energy efficiency.
Seal Doors and Windows
Doors and windows are common culprits when it comes to losing warm air to the great outdoors. Use draught excluders and weather strips to seal gaps under doors and around window frames. Take the time to check for worn-out seals and replace them if necessary. Draught-proofing strips are available in either foam or metal and are straightforward to fit around doors and window frames. Remember that ventilation is essential, so do not block intentional air vents designed to prevent condensation and ensure proper air flow.
Upgrade to Energy Efficient Windows
Replacing old, inefficient windows with double or triple-glazed units can dramatically improve insulation and reduce draughts. Energy-efficient windows come with a seal of quality that guarantees better retention of heat, minimising your reliance on heating systems and saving you money on energy bills in the long run. If window replacement seems overdue in your home, get in touch with us at Starglaze, and let’s explore your options together.
Insulate the Loft and Cavity Walls
A significant amount of heat can escape through uninsulated walls and lofts. Consider adding insulation if your home is lacking in this area. Loft insulation is a layer of material laid between the joists on your loft floor, while cavity wall insulation involves filling the gaps between the external and internal walls of your home. Proper insulation can make your property warmer, quieter, and more energy-efficient.
How to Draught Proof Your Home
Draught-proofing is a simple and effective way to improve energy efficiency, reduce heat loss, and create a more comfortable home. Use this quick guide to identify key areas and solutions.
| Area | Solution | Benefit |
|---|---|---|
| Doors & Windows | Install draught excluders and weather strips around frames and gaps. | Reduces heat loss and improves indoor comfort. |
| Windows Upgrade | Replace old units with energy-efficient double or triple glazing. | Improves insulation and lowers energy bills long term. |
| Loft & Walls | Add loft insulation and cavity wall insulation where needed. | Prevents major heat escape and boosts efficiency. |
| Chimney | Use a chimney balloon or draught excluder. | Stops warm air escaping while maintaining ventilation. |
| Floors & Skirting | Seal gaps with flexible filler or sealant. | Improves insulation and eliminates hidden draughts. |
| Letterboxes & Keyholes | Install covers, brushes, or flaps. | Prevents cold air entering through small openings. |
Draft-Proof the Chimney
If your home has a chimney that you rarely use, consider using a chimney balloon, made from a special laminate, to block the draught while still allowing a small amount of necessary ventilation. This simple measure can stop your home’s warmth from literally going up the chimney.
Address the Floorboards and Skirting Boards
Gaps in floorboards and skirting boards can also let in cold air. Seal these gaps using a flexible sealant designed for wood floors, which can handle the contraction and expansion of the wood. Sealing these seemingly insignificant gaps can enhance room insulation substantially.
Treat Keyholes and Letterboxes
To prevent cold air from sneaking in through letterboxes and keyholes, invest in simple covers that can be easily fitted. A letterbox brush or flap is incredibly effective and stops a surprising amount of cold air from entering the home. Similarly, a keyhole cover can insulate while remaining discreet.
