It is not always the case that electrical ventilation units are required. Passive ventilation has come a long way since the conventional air brick. Air bricks are still installed by some companies but often this causes further problems due to the lack of a control element as these photographs demonstrate.
‘Ultrovents’ are designed to overcome the problems associated with conventional air bricks making them ideal for use as a control measure for condensation. ‘Ultrovents’ contain a specially designed filter that reduces cold draughts while allowing up to 2.8 litres of water to escape through the unit each day. We offer long-term guarantees covering the installation of Ultrovents.
