How To Reduce Window Condensation Issues In New Homes - 19/08/2016

Winter. It can be bearable - even nice and cosy if your home is new, well heated and well insulated. But the downside to having a nice air tight home is that if it’s not well-ventilated, it’s probably going to suffer from condensation. If that is the case, don’t worry. Your house is one of 45% of New Zealand homes that have excess moisture leading to condensation.

There are lots of things that bring excess moisture into the home, or prevent it from leaving, that many of us do everyday. Cooking alone can add 3 Litres of moisture in your home on an average day. The other main culprits are showers and baths which add an average of 1.5 Litres of moisture to your home in a day. Drying your clothes, adds a whopping 5 Litres of moisture, and other household norms like washing your dishes, watering your pot plants, using an unflued gas heater and of course, breathing also create moisture. Whilst no one’s going to police your breathing, or stop you cooking, it helps to know just how much moisture is generated in a single day in the average Kiwi home and more importantly what you can do about it.

Occasional moisture on your windows for short periods shouldn’t be too much of a problem. When your windows look like they’ve been weeping however, your home most likely has a condensation problem.


Your windows don’t have to be weeping for there to be excess moisture

Looking at the windows of your house is a good way of indicating whether you’ve got an excess moisture problem, but your windows can also be deceptive. Double glazing your windows, especially when paired with great insulation, can reduce the appearance of condensation. As insulation keeps the home warmer, it’s able to hold more water vapour but it doesn’t remove the moisture from the air. This means that all the nasty side of effects of condensation can start to make an appearance.

Dampness is the first side effect of excess moisture which can cause issues for not only the house itself, but for you and your family’s health. Dampness feels unpleasant, can cause unwanted odours in your home, and can be hard to get rid of with dehumidifiers alone. Excess moisture can warp wooden window frames and can cause your curtains, wallpaper and other furniture to grow mould. Mould in your home can be a big health risk, especially for allergy and asthma sufferers: installing an HRV Ventilation system could save you money and stress in the long run by assisting with condensation control.


How do I know if ventilation will solve my condensation problems?

Home ventilation’s sole purpose is helping dry air circulate your house. This is so important for your comfort and for the structural longevity of the house. Introducing a home ventilation system early on in your new home should be considered so that you can avoid the side effects of excess moisture altogether. However, if this was side-stepped or you underestimated how much ventilation your house would need, it’s never too late and the positive effects can be felt almost immediately.

HRV ventilation systems use a system called to positive pressure to replace the air in your house with dry filtered air from your roof space between two to four times each hour. If you are after less or more ventilation, you can control this with a really easy-to-use touch screen pad. You’ll be able to say goodbye to excess moisture, condensation and dampness, and hello to a more comfortable, clean environment.

In New Zealand, there are two main types of ventilation, and if you’ve got a new and airtight home, positive pressure or roof cavity heat transfer system ventilation will be adequate for your home.

Ventilation can also help make your home fresh and allergy-friendly

A home ventilation system makes your home more comfortable, whilst making the air safer to for you to breathe. But another bonus is that your house will be easier to warm in the winter and quicker to cool in the summer as humid air is replaced with cooler, fresh air. Dry air warms faster than hot air, and so combined with a Heat Pump or other adequate home heating system, you’ll be able to enjoy an even temperature around your home and not have to worry about excess moisture damage. In summer, ventilation circulates the cooler air from your roof space – the first place to cool down on a hot summer’s day.

 Because fresh air is being taken from the outside, HRV’s filtration system captures over 90% of dust particles, pollen and bacteria before they enter your home, making it extra allergy friendly. If you can already see mould, you should be considering a ventilation system sooner, rather than later. But even if you can’t see it, allergy aggravators, like pollen spores and dust mites could be floating around your home, triggering asthma and allergies, making a ventilation system so beneficial for a new home.

Another great aspect to good ventilation is the removal of odours from your home. Cooking, pet and chemical odours often linger long after the window’s been left open, making for a smelly and uncomfortable living environment. A ventilation system however can help remove these odours by forcing that stale air outside and ventilate the house with continuous air changes.

Remember that if your house suffers from condensation, the sooner you get onto installing a home ventilation system the better. You’ll rest easy knowing your home is dry and healthy – the perfect Invironment for your family.
