It is important to minimize moisture in your home through proper heating & ventilation. These tips will help you optimize your indoor climate.
Out with the moisture
Reducing the accumulated moisture in your home before Winter months is particularly important to prevent any build up of damp. This can be achieved by fully opening all of your windows for a few hours. Particular attention should be paid to ventilating wet rooms and bedrooms, daily if possible, as these rooms are often a lower temperature which is favorable for condensation.
Check outlets (shaft)
Annually cleaning the external entrance to your trickle vents will ensure they perform at their peak. Vents are usually located through walls or windows and should be cleared of any dust, cobwebs or foliage. Rationel trickle vents are protected with insect mesh to prevent debris entering the interior.
Exhaust or vents
Trickle vents are ideal for maintaining air circulation, particularly in colder months when an open window may be undesirable. A number of Rationel windows also come with a night-vent function, meaning the sash can be locked in a slightly open position for secure ventilation.
What air change level is suitable for your home?
Air change requirements differ between rooms in your home, with bathrooms and kitchens requiring the highest level of ventilation. Rooms should ideally be aired via window opening for 5-10 minutes per day, this will ensure the air within your home is fresh.
Air every day
This applies to all living areas and especially to bedrooms and bathrooms, even if there isn't condensation on windows. It is important to air rooms even during wet or cooler weather.
Allow air to circulate
Leave doors open between the different rooms so that air can circulate freely throughout the day.
Maintain a constant indoor temperature throughout all rooms, 20-21 degrees is ideal.
Wet clothes create plenty of moisture
It is important to keep windows open if you choose to dry your clothes indoors.
If you have mechanical ventilation, it is important that it is set correctly in relation to your particular property and that the facility is regularly maintained according to supplier's instructions.
New windows in an older house
If you live in an older house where the windows have been replaced with new ones, it is quite natural for the windows to become externally misted in colder months, as the house has become more airtight. You should ensure that your property has adequate ventilation openings through exterior walls and ducts in the ceiling (ideally there should be at least one in each room).
