A simple solution for 2-4 SAP Points
Airex Floorvent is a solution designed to combat heat loss in suspended timber floors. Smartly replacing traditional air bricks under floorboards, Airex bricks feature built-in sensors to open and close only when necessary, keeping homes warmer for longer.
Our low-cost, high-impact solution can contribute 2-4 SAP points to the EPC rating in most homes and is eligible for schemes like SHDF, HUG, and more.
Airex IN SAP and RdSAP
Airex Floorvent can be modelled in both SAP and RdSAP using the dedicated Appendix Q calculation sheet which can be found, with supporting documentation, in the resources below.
For a guide on how to use Appendix Q with RdSAP have a look at the video too. For further information please contact the team who will be happy to help

how does the airex floorvent work?
The Airex brick is a smart ventilation control that replaces existing air bricks at a sub-floor level (under the floorboards). The Airex bricks have in-built sensors to measure the environmental conditions (such as temperature and relative humidity) and use smart software algorithms to automatically regulate airflow.
Each brick closes to reduce heat loss and improve thermal comfort but opens to reduce humidity and stop mould and damp.
Robust trials have shown that Airex Floorvent can save an average of 12% of whole home heat loss and led to the system being included in SAP (EPC). For most homes Airex can contribute 2-4 EPC points.
