Underfloor ventilation

Contact us

When it comes to underfloor ventilation, traditionally, builders would place underfloor vents on opposite sides of the house in the hope that air would enter a vent on one side of the underfloor and then exit via the opposite vent. They hoped that this would remove the damp and musty underfloor air with clean air from the outside. 

However this does not work as science tells us that the air movement within a house is upwards, similar to a chimney. This is called a ‘stack effect’. Underfloor vents were supposed to remove moisture from the property but they actually contribute to increased moisture during the hot summer months and increase heating costs in the winter months due to sucking cold air in from the outside.

Solutions for underfloor ventilation problems

If your underfloor is contributing to having a cold home in the winter then it could be recommended that an underfloor vapour barrier is installed. Our patented CleanSpace system will cover your entire underfloor and if you opt for our foil insulation it will also act as a thermal barrier, reflecting heat back into the property. The CleanSpace system will be pinned to the underfloor walls to ensure that no moist air will be able to rise up into your home.

As there is no need to cover up the underfloor vents there is no risk of wet rot or dry rot occurring on your timber as fresh air is constantly coming into your property through the vents. The underfloor vapour barrier will help reduce the levels of humidity in your home which will lead to an increase of temperature during the cooler winter months.
