    Does a garden house need ventilation and why?

    Proper ventilation – or air movement – is essential for any garden room, including wooden ones. The good news is that it’s very straightforward. Simply opening windows and doors is enough. For instance, tilt and turn windows, which are standard in all Summerhouse24 garden houses, let you conveniently control the airflow.

    Have you ever noticed the fresh air in log cabins compared to modern buildings? This is partly due to the unique properties that wood has. Wooden structures are often said to “breathe”, because they let moisture move through them. This process makes the wood expand and contract, which means wooden buildings are engineered with a little bit of extra space to let this process happen. These small gaps provide small openings for air to move through.

    How do I know if my garden room has poor ventilation?

    Some signs tell you the building has a problem with ventilation. Here’s what you should look out for:

    • Stuffy and stale air: Lack of fresh air leads to a stuffy or stale feeling in the room.
    • Odours: Persistent smells often mean there isn’t enough air circulation.
    • Condensation: Accumulating water on the inside of windows can warp wood and make paint peel. It also encourages mould and mildew growth.
    • Mould and mildew: Mould is bad for your health, the indoor air and can also damage the wooden structure.

    How do I deal with condensation during rainy weather?

    There’s no need to panic if you notice increased windows condensation. This is normal during rainy or cold weather.

    To effectively deal with the excess moisture you can consider using the following options:

    • Use a dehumidifier to remove excess moisture from the garden room.
    • Heat up the room when it is cold. The hot air will go outside. Don’t forget to open a window, or even better, two, to let out the moisture.

    It’s important to protect your garden room or log cabin from moisture. Make sure the wooden garden building is properly treated and don’t leave the building unattended for long periods when the weather is cold or rainy.

    When wood is exposed to too much moisture, it can warp or become damaged. It’s good to know that thinner wood is more likely to warp, which is why almost all of Casetasdejardin24’s garden room’s wall planks are made from thick wood – at least 44mm.

    What types of ventilation are there?

    Here’s a short overview of the types of additional ventilation you can use for your wooden garden house.

    Ventilation Options:

    1. Natural or passive ventilation: Keep windows ajar or use vents.
    2. Electric Air Conditioner: Great for both cooling and heating.
    3. Combination of passive and electric ventilation.

    Passive Ventilation or Natural Air Circulation

    Natural air circulation is easy to achieve by keeping your windows slightly open. Having openings on the opposite sides of a building is the most effective way, because for air to be able to move it needs a way in and a way out.

    For additional ventilation, two vents can be installed. One at the front of the garden room and one at the back. It’s best to have the building positioned in a way that the prevailing winds hit the gable end of the building – creating more natural air movement. To keep out rodents or bugs, add screens to the vent openings.

    You can use gable vents, wall vents or even a roof vent like a whirligig to increase passive ventilation in your garden room.

    Gable Vents

    Gable vents are installed at the gable ends (triangular ends of a building’s roof). They can both be placed high up, or one can be positioned low – to facilitate better air movement.

    Wall Vents

    In bigger buildings, gable vents can be paired with wall vents. The wall vents will be placed close to the floor. The air will come in through the wall vents and exit through the gable vents. It’s worth noting that the vents should have the right balance of intake and exhaust.

    Whirligig

    Whirligigs are dome-shaped vents that are installed on the roof. When the wind blows, it makes the whirligig spin, which creates a vacuum. They’re usually used with other types of vents – like wall vents – and they can be effective in pulling out the hot air.

    Electric Air Conditioner

    In Spain, an electric air conditioner can make the perfect addition to your wooden garden house. With an AC you’re always in control and your garden sanctuary is always at just the right temperature – even during a heatwave

    ACs are great for dehumidifying your cabin or garden room, especially if you live in a coastal area. It’s also good to consider the cost of electric heating and cooling. Choose an air conditioning unit that is energy efficient to save money.

    An AC with a smart controller can be a great choice if you want to cool or warm up your garden room or cabin ahead of time, especially if it’s located further away.

    Get a dual-function air conditioner to keep you warm when it’s cold and to heat up your garden nest when the temperatures drop.

    Conclusion

    Natural airflow is easy to achieve in wooden garden buildings and additional ventilation isn’t typically needed. When you open doors and windows sufficient air circulation is guaranteed. Additional ventilations options can be beneficial when issues come up, but they are generally not needed for most wooden garden houses and log cabins.
