PIV Ventilation Systems Northern Ireland
The permanent, proven solution for condensation and mould. Specialising exclusively in the professional installation of Drimaster and Flatmaster Positive Input Ventilation (PIV) systems, tailored to your property type.
What is Positive Input Ventilation (PIV)?
PIV is a highly effective, low-energy ventilation method. A discreet unit draws fresh air from outside (usually via the loft), filters it to remove pollutants and allergens, and gently introduces it into the home. This creates a slight positive pressure, forcing stale, moisture-laden air out through natural leakage points around doors and windows.
The result is a continuous supply of clean, fresh air that dilutes humidity and eliminates the conditions that cause condensation and black mould. PIV is widely recognised as the most effective long-term solution for damp and condensation problems in homes — far superior to dehumidifiers, extractor fans, or anti-mould paints.

What type of property do you live in?
Drimaster — For Houses with Lofts

The Drimaster system sits out of sight in your loft. It draws air through the roof space, passes it through high-grade filters, and delivers it into your home via a single, discreet ceiling diffuser usually located in the hallway or landing. It's the ideal solution for two-storey houses, bungalows, and any property with accessible loft space.

Perfect for Northern Ireland's many apartment developments and terraced properties without attic access.
