Flat PIV installation for apartments

Flat PIV installation requires careful planning to ensure correct airflow and compliance with building layouts. Our engineers assess external wall positions, ceiling voids, access routes and natural leakage. Then we will recommend the right positive input ventilation unit for the property.

Installation is discreet and designed to blend seamlessly into the property. Most systems can be installed with minimal disturbance and no major structural changes.

Flat PIV units and airflow control

Flat PIV units are compact, efficient and purpose built for apartments. They deliver consistent, fresh filtered air flow while maintaining low noise levels. High quality filters remove indoor pollutants, before fresh air enters the living space.

These systems are ideal for flats with limited natural ventilation or properties where opening windows is not practical due to location or noise.

How does it work:

Unlike loft systems, flat PIV units draw air from outside or communal areas. They then introduce the outdoor air directly into the living environment. This controlled airflow reduces moisture levels and helps prevent black mould growth in enclosed living spaces. All done without the need for extractor fans with high running costs.

Benefits of flat PIV systems

Flat PIV systems prevent condensation on windows and walls. They help control humidity levels and improve indoor air freshness. This is particularly important in kitchens, bathrooms and bedrooms.

They are widely used in private flats, social housing and managed apartment blocks due to their reliability, energy efficiency and low maintenance requirements.
