I hold a problem beside condensation within my flat, will putting an nouns brick contained by the wall assist to moderate this? ...


to some degree but once it's humis outside it will be lately as bad,
buy a dehumidifier they dry the atmosphere using a refrigeration systen which dries the air highly efficiantly with no impact on the warmth of your room
it will take out abundant litres of water out of the room per hour depending on the size of the component.
they are used to dry out building after floods and in museams and librarys to maintain things dry.
Not sure around that, as we have one and the same problem (with no air brick). We be told to use a couple of these Silicia Gel sachets (usually found within new shoe boxes "Do not eat") on the windowpane sills....

Might be worth a try.
Answers:    Check first for water fog sources and eliminate or revaluate
A source of dampen vapour comes from gas fires: yes the burned gas turns to river vapour!
Ditto for gas cookers.
Butane gas heaters pump out gallons of wet vapour and grease and paraffin heaters ....lakes
Installing nouns bricks involves cutting contained by to the masonry and thus a bit of a mess.
Have you considered installing Vent-a Matic
ventilators in window?
They are not very pretty but are a cheap road to get freshening in ( fitted for smaller number than lb50 per pane)
See my article on diy double glazing also.
Double glazing reduces condensation on cup (but does not eliminate the source of the hose down vapour)
As an alternative to air bricks you might consider using circular ventilators.
The holes for these can be cut using a core drill approx 100mm diameter so no plastering needed.
Do you hold a chimney?
Is it sealed up
An uncap fire helps to move nouns .
Fieplaces and flues should be vented next to an air brick or other ventilator
thaw out air hold more moisture than cold nouns so dew points occur where on earth hot air meet cold.
Consider mechanical extraction fan/s to circulate and extract nouns. You can get them near humidity sensors so as to activitate when a space reaches a specific humidity.
Agree with "Bomber" on this, however here are other ways to help this such as keeping the place "aired". Airless corners are particularlly prone to soaked. Allow air to circulate.
