Positive Input Ventilation (PIV) systems create fresh and healthy working or living environments by enabling the supply of fresh, filtered air into a property at a continuous rate.  This can be done via a loft space or wall.

Our PIV units help to prevent the growth of mould, eliminate surface condensation, and also reduce the populations of dust mites.  Our PIV units also offer a vast array of energy saving and health benefits.

Addiotionally,  our PIV units are perfect for retrofit projects !  Did we mention that they also come with a 5 year renewable warranty included?  Well they do!

Our PIV units create a healthy living or working environment and are our most popular method of whole house or office ventilation.
