The Top 5 Damp Cures That Don’t Work
1 – Dehumidifier
Dehumidifiers remove water only from the immediate area and require regular emptying of the condensate. They don’t provide ventilation (changing stale air for fresh air), so can’t extract the moisture-laden air or remove the allergens and pollutants associated with damp, humid homes. They are noisy and expensive to run.
2 – Anti-Mould Paint
Painting the interior walls will mask the signs of mould, but without treating the cause of condensation, the patches will soon re-appear.
The biggest cause of damp problems from condensation is inadequate ventilation, so sealing up the natural leakage points of the exterior walls with anti-damp paint will further exacerbate the problem of stale, humid air being trapped inside the home.
3 – Insulation Double Glazing
Ceilings and wall insulation will keep your home warmer as will double glazing, but any measures that stop heat escaping also trap humid air inside the home. It’s a myth that making your home warmer will prevent condensation. The better-sealed your home is, the more robust a ventilation system you’ll need to lower humidity and ensure good indoor air quality.
4 – Opening Windows
Opening windows when cooking, bathing and drying clothes will help to reduce moisture levels in the immediate vicinity. But if your home is very well insulated, or indeed has a few cold spots, then opening a few windows won’t be enough to remove humidity and stop mould spores germinating. In winter, it’s often less cost-effective to open windows as heat is lost and the indoor temperature drops.
5 – Passive Dehumidifier Vents
Passive dehumidifier vents work by allowing water vapour to pass to outside through a wall vent with a draft excluder. They come highly recommended by builders as they’re easy to fit. They are effective at maintaining a low level of background ventilation, but can’t deal with high levels of humidity or indoor air pollutants. They work by slowly diffusing air rather than extracting it, so can’t tackle high moisture production from showering, bathing, cooking and drying clothes indoors.
So what is the one that DOES?
For properties affected by condensation dampness, the most effective solution is Positive Input Ventilation (PIV), technology invented by Nuaire over 40 years ago. The PIV process involves drawing fresh air from outside into a fan located in the loft area and gently pushing the filtered air into the home. This process is called positive pressurisation.
Moisture-laden stale air is forced out through the natural leakage points and as a result the humidity is drastically reduced and allergens are removed from the air creating a healthy indoor environment
Quiet and energy-efficient in their operation, our popular Drimaster Eco range of PIV systems will reduce the overall maintenance costs of a property by protecting the fabric and materials in the home. The Drimaster Eco range is extremely cost-effective at just 1 penny per day to run. Installation is quick and unobtrusive, making it ideally suited to refurbishment projects.
