Boarding Over Walls where there is condensation

Anonymous user 23/02/2024 - 3.05 PM

Hi there, We have been told we have condensation in the walls are looking at ways of repairing the walls. The condensation seems to come from the central heating pipes between the walls. We have removed small areas of plaster to exposure the brickwork and allow the wall to breathe. Would it be possible to leave the wall in its current state and cover the lower section of the wall with Tongue and Groove Boarding. leaving a small gap in between the wall and boards? We have been advised that this would allow the wall, in its current state, to continue breathing. Thanks very much

There are several types of breathable external wall insulation boards available such as Woodwool board that provides good thermal insulation and at the same time allows the moisture vapour from the house to safely evaporate into the outside air. Woodwool boards would generally be coated with a lime render which itself is breathable so unlike the old cement type renders, it does not block the egress of water from the walls.
