s. Close and secure roof light (where fitted)
and all windows making sure no curtains are
trapped but are hanging free.
t. Preferably, soft furnishings should be
removed and stored in ideal conditions,
or, if they are to remain within the unit, it is
advisable to place cushions and mattresses
separately on end or edge to allow a free
movement of air around them.
u. Secure exterior windows. Many people
leave bowls of water-absorbing crystals or
common salt as a means of withdrawing
moisture from the air. No moisture means
no mildew and damp, so the practice is
worthwhile.
v. Ensure all fixed ventilation points (high, low
and trickle vents) are clear from debris and
obstructions.
14.2 Condensation
What is condensation?
Condensation is the process of change of
water from its gaseous form (water vapour) into
liquid water when it comes into contact with a
surface that is cold. Condensation generally
occurs when warm air cools quickly and loses
its capacity to hold water vapour, and as a result
condenses to form droplets
Why condensation occurs
Condensation occurs when warm air meets
a cold surface. The level of condensation will
depend upon humidity levels, how moist the air
is and how cold the surfaces are they come into
contact with.
If the temperature falls below the dew point
temperature, it is quite normal for condensation
to occur on the external walls and any other
cold surface.
When condensation occurs
Condensation occurs usually in winter months,
because ambient temperatures are colder
(leading to cold surface) and windows, vents
and doors are opened less so the moist air
cannot escape.
Where condensation occurs
Condensation will occur where warm moist air
is put into the atmosphere in areas such as in
bathrooms (during showering) and in kitchen
areas (during cooking).
In bedrooms when people sleep (or the lounge
when a pull out bed is used) the warmth from
their body heat and breath generates moisture
in the atmosphere which in turn condenses on
cold surfaces leading to visible water droplets.
Condensation will also form in cold areas where
air movement and ventilation is restricted, (e.g.
cupboards, wardrobes, corners of rooms, etc.)
What is important
It is important to provide ventilation and air
flow, so that warm moist air can escape, or
be externally cooled, and to use the heating
reasonably by not making rooms too warm
such that people perspire, as this will only serve
to generate more moist air and therefore more
condensation.
However, in particularly cold periods, where
the external ambient temperatures are low,
condensation may still form on external walls
as the wall insulation levels may well not be
thermally able to cope with the difference
between the internal and external temperatures.
