Don't Hide The Problem - Cure It

How Does PIV Work?

Designed as a low maintenance, cost effective and high quality solution, our whole house PIV unit is discreetly sited in the loft to continuously supply fresh, clean air into a property through gentle and positive pressurisation.

Stale and unclean air is then dispersed through natural leakage points - forcing out and eradicating condensation, mould and other air pollutants.

To lower space heating costs, our energy efficient PIV unit also utilises solar heat gain from within the loft space by filtering and breathing the air gently into the home.

* Clean, filtered air is drawn from the loft area and fed into the home via a diffuser located in the hallway

* Pollutants are removed

* Moisture and condensation are eradicated

Why Ventilation is SO Important

Keep a happy, healthy home. By removing condensation, mould and air borne pollutants - owners and tenants will be happier and healthier.

Avoid re-decoration costs. Left untreated, condensation mould can beomce an expensive nightmare to rectify.

Protect your investment. Whilst condensation is typically evident from steaming windows, damp patches and black mould, it can also develop in places where it is impossible to see.

No need to open windows. Not only will that benefit allergy sufferers or those living in urban enviornments, but during colder periods, significant energy loss occurs by opening windows, thererby increasing heating costs and energy loss.
