Condensation and Ventilation Products
Permagard sell a range of products designed to reduce condensation, with a focus on highly effective ventilation systems. We have a ventilation system to meet your exact situation and budget. We also have high performance Anti Mould products that effectively tackle black mould, providing lasting protection .
Condensation Control Methods & Products
Condensation control can be achieved by various methods. These span simple passive ventilation systems for local condensation control to whole house systems.
Ventilation Systems
At Permagard, our ventilation spans the following systems:
- Passive Ventilation - designed to be installed in smaller areas and rooms with problem condensation - shop our PermaVent passive air vents
- Positive Input Ventilation (PIV) - whole property systems that introduce fresh filtered air, encouraging healthy airflow throughout the home
- Heat Recovery Ventilation - energy-efficient units that extract moist, stale air while warming incoming fresh air to reduce condensation and improve air quality
Our whole flat or house positive input ventilation systems use condensation control units to ventilate the entire house from a central position. They work by displacing and replacing moisture-laden air with fresh filtered air.
PIV systems also force contaminants out of the property. This immediately improves indoor air quality and eliminates mould growth. You can also look to stop condensation forming on internal surfaces with an anti condensation paint.
Anti Mould
As well as taking positive steps to improve ventilation and reduce condensation, you may also need to tackle existing black mould. Our anti-mould products will kill off mould and stop it coming back. We stock anti-mould paint, as well as a mould-resistant paint and a handy mould remover kit.

* Kair Heat Recovery Unit and Kair Mini Single Heat Recovery Unit are single-room heat recovery ventilators. They can be installed in individual rooms (including basement rooms with an external wall) and can help improve overall air quality in the home, but they are not designed to ventilate an entire basement or whole property on their own; multiple units or a dedicated whole-home system would be required.
