Innovative Roof Space Ventilation for 

Existing Social and Private Housing

Installed from inside to aid condensation and mould control

The KimaAir Inside-Out vent is ideal for both social and private housing where cost effective ventilation is required to aid condensation and mould control


Installed easily from inside the roof space, the KimaAir Inside-Out offers a major advantage as, previously, it has been difficult to retrofit ventilators once the roof tiles have been laid. Moreover, the innovative design eliminates the need to remove or replace the roofing underlay.
