Insider Tips On Preventing Conservatory Condensation

With the temperature now slowly heading into single figures, conservatory owners will be facing up to the problem of preventing condensation. It’s an issue that will rear its head for both new and experienced conservatory owners. Read on below to find out what you can do to prevent the build-up of condensation in your conservatory.

Why do conservatories produce condensation?

Conservatories are designed to be both air and water tight and with no natural ventilation, condensation is a natural by-product when the temperature starts to fall outside. Doors and windows invariably remain closed during the winter to retain heat, which in-turn creates a build-up of airborne water-vapour, creating condensation on the glass panels.

How to prevent condensation in your conservatory

Ventilation is the key to combating air moisture and reducing the amount of condensation that can build up within the space. This is a rule that can also be applied to other areas of your home, especially in the kitchen and bathroom. A few tips to follow include:

– Increase the temperature. There are a number of ways this can be done. Some people install heated floors or radiators when building their conservatory, keeping winter in mind. If you do not have these fitted, then purchasing a reliable portable heater will prove to be effective.

– Where possible, keep the windows slightly ajar allowing fresh air to circulate around the room. Trickle vents are also a good solution and in some cases they can be retro-fitted onto existing windows. This slowly lets in a constant stream of low level air that ventilates the room without creating a dramatic drop in temperature.

– Ventilate the home wherever possible. This can be difficult on particularly cold days, but activities such as drying clothes, cooking and bathing can quickly create a lot of air moisture that can lead to unsightly mould right across the house, including the conservatory.

Why is condensation in the conservatory a bad thing?

Condensation build up creates more issues than just the misty water that appears on glass panes. When this becomes a regular occurrence the moisture will begin to create black mould around the edge of the windows. If left untreated, the mould can spread around the windows, walls and ceilings – anywhere moisture is present. On wooden windows this is a particular problem as the mould will begin to rot away the material.

Beyond the aesthetic problems condensation can create, health issues may also become a point of concern. Asthma sufferers may begin to use their inhalers more often due to moisture in the air irritating their airwaves. Extended exposure to condensation and mould could even lead to bronchitis, sinus problems or skin rashes for some people.

How to deal with conservatory condensation

Even with regular ventilation around the home, some conservatories may still continue to experience high levels of condensation. In cases like this, a portable dehumidifier will help to extract the moisture from the air before it begins to build up and show on the windows. Another option is to purchase a window vacuum which easily glides over the surface of the glass removing the condensation with it. This is a much easier method of removing condensation instead of constantly wiping down the windows with cloths. Drip strips can also be used, as these absorbent pieces of material stretch along the lower edge of the window, catching condensation before it reaches the frame.


Some conservatory owners will have more work to do than others this winter to remove condensation. Either way, by taking note of the above advice we are confident you can win the battle against condensation and enjoy your conservatory in warmth and comfort.
