Positive Input Ventilation (PIV) Systems for Condensation Control
Condensation is one of the leading causes of mould growth in UK homes. If you’re constantly wiping down windows, noticing black mould around window frames, or struggling with stale, humid air, a Positive Input Ventilation (PIV) system could provide the long-term solution.
At The Damp and Mould Experts, we install high-quality PIV systems that improve airflow, reduce moisture levels, and create a healthier indoor environment. Before recommending installation, we’ll assess your property to make sure a PIV system is the right choice for your home.
What Is a Positive Input Ventilation (PIV) System?
A Positive Input Ventilation (PIV) system is a whole-house ventilation solution that works by introducing fresh, filtered air into your property. This gentle airflow helps dilute humid, stale air and encourages it to escape through natural ventilation points, reducing condensation and improving indoor air quality.
PIV systems are particularly effective in homes where poor ventilation is causing recurring condensation and mould.
Is a PIV System Right for Your Home?
A Positive Input Ventilation system may be the ideal solution if you experience:
- Persistent condensation on windows
- Black mould around windows, walls or ceilings
- Damp caused by excess humidity
- Poor airflow throughout the property
- Musty odours
- Mould returning after cleaning
If you’re unsure whether a PIV system is suitable, our specialists will inspect your property and recommend the most effective solution.
