Tip #11 - Mould Exposure

Moulds are a common phenomenon in areas that are wet, or damp. Usually in bathrooms, but also in bedrooms that are poorly insulated. In order to exist mould requires

1. Moisture
2. Food source (dust, dander, etc.)
3. Warmth (mould doesn’t grow in a cold environment)

Mould spores can be allergenic, causing irritation of eye, nose, throat and lungs. Some moulds, referred to as ‘toxic moulds’ (mycotoxins) can pose serious health risks (often referred to as sick building syndrome).

In order to remove the mould yourself – you must remove all leaks from the plumbing system, building envelope and ensure that your air conditioning drip pans are clean and unobstructed. In addition, it is viable to keep a low relative humidity in the house – ideally below 50%. Finally, remove and the moulds with a mould cleaner.

If the building material has been subject to long periods of dampness it is advisable to remove them. In many cases wall mould can be eradicated by insulating the wall with appropriate material. This reduces dampness/condensation on the walls. If the mould growth has reached high levels it is recommended to contact professional help.

Tip #10 - External Wall Insulation

External wall insulation is more expensive than the previous 2 options as it must be applied with a durable finish to withstand the elements. However, it is more effective at reducing heat loss due to the greater insulation thickness that can be applied.

Customers with a small living area in the house often choose this solution over the internal dry-lining insulation.

Tip #9 - Internal Wall Insulation or Dry-Lining

Internal insulation involves fixing a layer of insulation to the internal surfaces of the external wall. This layer of insulation is then finished with plasterboard. It is important that the insulation sealed with a vapour check in order to avoid humid air penetration from within the house. Internal insulation is ideal for retro fit and represents one of the most common insulation methods for existing dwellings.This also has the effect of eradicating mould which is common on cold, exposed walls.
