Ventilation and draught proofing

Ventilation is important for maintaining good indoor air quality, reducing the risk of damp and mould, and removing moisture and pollutants from your home. 

This can be done through natural ventilation, such as opening windows and installing trickle vents, or through mechanical ventilation, such as installing extractor fans in your kitchen and bathrooms.  It is important that these ventilation systems are not blocked up or sealed.

But problems can arise when too much air enters your home through uncontrolled draughts. Draughts commonly occur through gaps around windows and doors, fireplaces and letterboxes. This can make your home feel colder in winter and hotter in summer and could increase your home’s running costs. This could be addressed by draught-proofing your home.

Draught proofing is one of the simplest and most cost-effective ways to make your home more energy efficient. Measures can range from fitting draught excluders around doors, installing chimney balloons, letterbox covers, or hanging heavier curtains.

Whilst in some cases you could install your own draught-proofing measures, it’s important not to block up controlled ventilation openings. If you’re unsure, you should seek advice from a qualified professional. You can find qualified and reputable installers through TrustMark.
