Home Ventilation by Just Lofts & Build

Breathe Cleaner, Fresher, Healthier Air

At Just Lofts & Build, we don’t just improve lofts – we improve the air you breathe. If your home suffers from condensation, damp, mould, or you’re concerned about allergens like pollen, dust mites and pollutants (including harmful Radon gas), we have the solution.

We supply and install low-energy Positive Input Ventilation (PIV) systems designed to cure condensation, expel pollutants and create a healthier indoor environment all year round.

Our Systems

DRI-ECO-LC (Loft Control)

  • Designed for homes with loft space.
  • Continuously introduces fresh, filtered air from the loft into your living areas.
  • Drives out stale, moisture-laden air to stop condensation, mould and indoor pollutants at source.
  • Reduces allergens such as pollen, dust mites and traffic fumes.
  • Low running costs and virtually silent operation.

DRI-ECO-HEAT-HC (Hall Control)

  • Same PIV technology with built-in heater option for improved comfort.
  • Minimal maintenance – filters only need replacing every five years.
  • G4 filters block external pollutants while expelling internal ones from cooking and cleaning.

Flatmaster from Nuaire

  • Purpose-built for homes without loft space.
  • Wall-mounted, low-energy PIV system introducing filtered air at a constant low rate.
  • Eliminates condensation, damp and indoor pollutants including Radon gas and carbon monoxide.
  • Keeps outdoor allergens such as pollen and traffic fumes at bay.
  • Can also ventilate basements, cellars and other hard-to-reach areas.

Why This Matters

  • Condensation & Damp: NHS guidance confirms mould can cause allergic reactions, asthma attacks and skin irritation. Removing the cause of mould protects your health.
  • Air Quality: PIV keeps harmful indoor pollutants and allergens to a minimum while filtering out traffic fumes and pollen from outside.
  • Comfort & Energy: Low-energy operation with long filter life (five years) means low running costs and minimal maintenance.

Don’t just mask condensation and damp – remove the cause. Just Lofts & Build install PIV systems quickly and cleanly, giving you a drier, healthier, more comfortable home.
