Condensation is an increasing issue in both private dwellings and commercial premises.
Condensation is a direct result of improved draught proofing & insulation. It occurs whenever warm, moist air meets a surface or object cold enough to chill any moisture in the air below its dew point. Accompanying Condensation is an increase of mould growth, general mustiness and other household pollutants.
Condensation is often considered a trivial problem that can be easily dealt with; unfortunately this couldn’t be further from the truth. In fact, condensation is probably the most difficult type of dampness to control due to the varied factors that can cause it. It is most problematic in the winter time, triggered by a drop in exterior temperatures.
The introduction of Part F of the Building Regulations 2009 has seen a continued move towards draught proofing new and existing builds to conserve energy and reduce carbon emissions. Natural ventilation has been drastically reduced in current energy efficient homes that have been fitted with effective insulation, and rendered air-tight with triple glazed windows. This means that the moist air generated by everyday activities is unable to escape; increasing the humidity in your property and leading to condensation and visible damp spots. If allowed to continue untreated, Condensation can cause wall materials to decay, and in extreme cases can cause Wet or Dry Rot in untreated timbers that are in contact with the dampness.
Mould is capable of growing on dry or painted walls as long as there is moisture in the air to sustain it. There are over 100,000 different types of mould; 23 of which have been identified as possible health hazards. Unfortunately, all of these hazardous types can all grow in damp buildings. All moulds are allergenic, and it is generally accepted that exposure to heightened mould levels can cause or trigger asthma in susceptible people, along with other respiratory and allergenic issues.
Mould is always related to a moisture or damp issue, and identifying the contributing moisture source is a critical part of any treatment plan. It is not advised to use household cleaning products to attempt to kill the bacteria, or to brush the mould off a surface. Brushing it or disturbing the mould will make the spores airborne and more likely to spread where they land, especially in damp conditions. A comprehensive and specialised chemical treatment program will eradicate the issue, but the underlying cause of the damp conditions must first be rectified. Otherwise, Mould may return at some time in the future.
McGuinness Building Preservation Ltd has decades of experience in dealing with Condensation and Mould in the homes of our affected clients.
Positive Ventilation Systems
A Positive Ventilation System (PVS) replaces the stale, moisture laden air with fresh filtered air in your work or living space. The dramatic reduction in humidity creates an environment where condensation and mould are unable to exist or grow.
In addition to this, the ongoing flow of fresh air represents a much healthier living environment; dramatically reducing pollutants from cooking or cleaning, along with removing airborne particles such as Pollen.
Our Positive Ventilation Systems offer an effective solution for the entire property, and operate as a pressurised system. The PIV unit introduces a continuous flow of fresh, filtered air into your property, offering a reliable and constant circulation of air from inside to outside.
Our units are an ideal solution for retro-fit projects, with minimal disruption to your property. Placed in the attic out of sight, there is minimal visual evidence of the units. Running costs are exceptionally low also; comparable to a 30w light bulb, they only cost a few cents a day to run.
For apartments, or buildings without an attic space, we also have a specially designed ventilation system based on the Trickle Ventilation principle. This system offers all the same benefits as the attic unit, operates via an external grille, and can extract up to 2.3 litres of moisture per unit per day. This system is designed for use in habitable rooms where it runs 24 hours a day with no noise.
