Positive Input Ventilation (PIV) units are one of the most effective solutions for tackling condensation and mould in single-storey properties. In the bungalows scattered throughout Leicester’s rural villages, damp and stale air can quickly build up due to limited air circulation — especially in homes with energy-efficient upgrades like double glazing or loft insulation.
At Weather Wise Solutions Limited, we specialise in ventilation improvements that work in harmony with your home’s layout. That’s why we often recommend PIV units for bungalows — particularly when trickle vents or extractors are unsuitable or insufficient.
As members of the Federation of Damp and the Damp Proofing Association, we follow best practice to deliver lasting, compliant solutions using trusted systems from PAM Ties.
🏡 Why Bungalows Struggle with Ventilation
Bungalows often have fewer natural ventilation pathways compared to multi-storey homes. With no stairwells or high-level windows, moisture-rich air from cooking, bathing, and even breathing can linger in living areas — especially in colder months when windows remain shut.
This leads to:
-
Condensation on walls and ceilings
-
Black mould on surfaces and around windows
-
Musty odours and poor indoor air quality
💨 How PIV Units Help
PIV systems work by drawing in fresh, filtered air (usually from the loft) and gently introducing it into the home at a constant rate. This steady airflow helps displace stale, humid air — reducing moisture levels and improving air quality.
Benefits include:
✅ Mould and condensation control
✅ Healthier living environments
✅ Lower humidity without heat loss
✅ Low running costs and near-silent operation
🏛️ Supporting Part F of the Building Regulations
Under Part F of the Building Regulations, all habitable homes must be ventilated adequately to remove excess moisture and pollutants. While not a replacement for extractor fans in wet rooms, PIV systems are a recognised supplementary ventilation method, particularly in existing buildings where retrofit upgrades are necessary.
In bungalows where DMEV or MEV systems are not feasible, PIV provides a reliable route to meet compliance while improving indoor conditions for residents.
🛠️ Professional Installation with Long-Term Support
At Weather Wise Solutions Limited, we assess your home layout, measure relative humidity, and recommend the most suitable system. We’ll even advise if subfloor ventilation or passive vents are needed to complement the PIV.
