How to Improve Airflow in Sealed Homes with PIV Systems

🏡 Airtight Isn’t Always Ideal – Here’s Why Sealed Homes Need Ventilation

Modern properties with double glazing, insulation upgrades, and draught-proofing are great for energy savings—but often terrible for airflow. Without adequate ventilation, these sealed homes become breeding grounds for condensation and mould.

At Weather Wise Solutions, we help homeowners tackle poor indoor air quality with Positive Input Ventilation (PIV) systems from PAM Ties. These systems restore fresh airflow, reduce humidity, and create a drier, healthier home environment.


🌬️ The Problem with Poor Airflow

In sealed homes, everyday activities like cooking, showering, and even breathing release moisture. Without natural ventilation, that moisture:
✅ Settles on walls, ceilings, and windows
✅ Encourages black mould growth
✅ Triggers allergies and respiratory issues
✅ Damages paint, plaster, and woodwork


🔧 How PIV Systems Work

A PIV unit draws in filtered, fresh air—usually from the loft—and gently distributes it throughout the home. This creates a constant air movement that:
✔️ Expels damp, stale air
✔️ Balances humidity
✔️ Prevents condensation build-up
✔️ Improves air quality throughout the property

PIV systems are discreet, quiet, and low-energy—making them ideal for modern and upgraded homes.


🏘️ Ideal for Homes With:

  • New or retrofitted insulation

  • Double or triple glazing

  • Blocked chimneys and sealed vents

  • Damp, condensation or musty odours

  • Previous mould issues

We follow GOV.UK ventilation guidance to ensure compliance with current standards for household air quality and health.
