What types of mould are there?

Mould is a widespread problem in many homes and buildings. There are different types of mould that thrive in different conditions. The most common types of mould include white mould, yellow mould, green mould, red mould and black mould. Each of these types of mould has its own characteristic features and health risks.

White mould: White mould is characterised by its light, fibrous structure. It often grows on damp surfaces such as wood or plaster and can trigger allergic reactions.

Yellow mould: Yellow mould has a yellow to golden colour and often grows on organic materials such as leather or fabric. It can cause respiratory problems and skin irritation.

Green mould: Green mould is one of the most common types of mould and can grow on various surfaces such as food and walls. It can be harmful to health and cause allergic reactions.

Red mould: Red mould has a reddish colour and typically grows in damp environments such as bathrooms or basements. It can lead to serious health problems such as respiratory diseases.

Black mould: Black mould is one of the most dangerous types of mould as it can release toxic spores. It often grows in damp, poorly ventilated areas and can lead to serious health problems.

How does mould typically develop?

The growth of mould in living spaces is a common problem that affects many homeowners. Mould typically develops in damp environments where mould spores can easily spread. The main cause of mould growth is moisture. Moisture in the air, whether due to leaky pipes, leaky windows, lack of ventilation or other reasons, creates an ideal environment for mould growth.

When moisture condenses on surfaces such as walls, ceilings or floors, these damp spots provide a breeding ground for mould spores to float in the air. These spores germinate and begin to form visible mould growth. The risk of mould growth is particularly high in poorly ventilated areas such as bathrooms, basements or kitchens.

Good ventilation is crucial to effectively remove moisture and ensure air circulation in the bathroom. This can be achieved by installing high-performance ventilation systems such as the BALNEO EX® series from Ventomaxx. These active exhaust fans for damp rooms allow individual control of the air supply in different rooms, helping to reduce moisture and mould growth.

There are different types of mould that thrive in different conditions. White, yellow, green, red and black mould are just a few examples. Each type of mould has different characteristics and can have different health effects. It is therefore important to recognise mould growth at an early stage and take appropriate measures to remove it.

To prevent mould growth, it is crucial to identify and eliminate the causes of damp indoors. Regularly ventilating rooms, especially after cooking or showering, can help to reduce moisture. In addition, special ventilation systems such as decentralised ventilation systems can help to keep the humidity at an optimum level and thus prevent mould growth.

 

 

More about white mould

The white-coloured form of mould, also known as "downy mildew", can occur in homes and other buildings. It often occurs in damp environments, such as bathrooms, kitchens or basements.

The causes of white mould can be many and varied. It is often due to damp, inadequate ventilation or unsuitable building materials. It is therefore important to identify and eliminate the sources of moisture in order to prevent the formation of white mould.

White mould can be harmful to health, so effective mould control is crucial. Removal of white mould should be done with care to prevent further spread of spores. Mould can spread quickly and should therefore be tackled as early as possible.

There are various methods of mould removal, depending on the extent of the infestation. From household remedies to professional remediation measures, the choice of method should be made carefully to ensure effective control.

More about yellow mould

Yellow mould is a special type of mould that often occurs in damp and poorly ventilated areas. The yellow colour is caused by certain pigments produced by the mould. Yellow mould can grow on walls as well as on organic materials such as wood or fabrics.

It is important to recognise and combat yellow mould at an early stage, as it not only looks unattractive but can also be harmful to health. Its spores can cause respiratory problems and allergies.

To remove yellow mould, it is necessary to thoroughly clean and dry the affected areas. Suitable protective measures such as gloves and respiratory masks should be worn. To prevent yellow mould from forming again, it is important to eliminate the causes of damp and poor ventilation.

If you discover yellow mould in your home, it is advisable to call in an expert to carry out professional mould remediation. This will ensure that the mould is effectively removed and no longer poses a health risk.

More about green mould

Green mould, also known as penicillium, is one of the most common types of mould found in homes. This mould forms green spots on surfaces and can grow on foods such as bread and fruit. Penicillium is not only an aesthetic problem, but can also be harmful to health, especially for people with respiratory diseases.

Penicillium needs moisture to grow, so green mould often occurs in damp environments such as bathrooms, kitchens or basements. It is important to identify and eliminate damp areas in the home to prevent the growth of Penicillium.

To eliminate green mould, it is important to thoroughly clean the infested areas. Use protective clothing and respiratory protection to protect yourself from the mould spores. Dispose of infested food or materials properly to prevent further spread.

Preventing green mould involves controlling the humidity in the home, airing it regularly and using ventilation systems to reduce moisture. By keeping rooms well ventilated and dry, you can minimise the risk of mould infestation.

More about red mould

Red mould, also known as Aspergillus sydowii, is one of the types of mould that can occur indoors. It is characterised by its striking red colour, which distinguishes it from other types of mould. Red mould can occur in various places in the home, especially in damp environments such as bathrooms, kitchens or basements.

Like all types of mould, red mould needs moisture to grow. It is therefore important to identify damp areas in the home and keep them dry to prevent the formation of red mould. Good ventilation can help reduce moisture and inhibit the growth of mould.

It is important not to ignore red mould as it can be harmful to your health. Contact with red mould can cause health problems such as respiratory irritation, skin rashes or allergy symptoms. It is advisable to call in an expert to carry out professional mould removal if red mould is suspected.
