Cost effective solutions
for condensation and mould
What is the problem?
1 in 5 properties in the UK still
suffer from Condensation
Why?
Our role - to provide you with information
on Condensation and Mould
• Why does it occur?
• What are the solutions?
• What are the benefits?
The Housing Health and Safety
Rating System
Requires dwelling to be free of Category 1 hazards.
Hazards in Group A are classed category 1.
Hazard Group A - Physiological Requirements
Damp & Mould Growth
Extract from the HHSRS
Description of the hazard
1.01
This category covers threats to health associated with increased prevalence of house dust
mites and mould or fungal growths resulting from dampness and/or high humidity's. It
includes threats to mental health and social well-being which may be caused by living in the
presence of damp, damp staining and/or mould growth.
Damp and mould: why you should care!
In Europe, 50% (depending on the country) of the indoor
environments where human beings live, work and play are
damp. Too much moisture makes a home stuffy and gives it a
faint odour. Humid walls create a coldness that makes more
heating necessary and increases energy bills.
World Health Organization is concerned about this situation
because excessive dampness and mould are a threat to health.
Occupants of damp or mouldy buildings are at increased risk of
experiencing health problems such as respiratory symptoms,
respiratory infections, allergic rhinitis and asthma.
Building Regulations state that extract fans should be
fitted but why do intermittent extract fans fail to provide
a solution?

Besides the 112 Pints of moisture per week,
what else is present in the air?
The costs of poor ventilation to landlords?
•Ongoing maintenance (painting over the problem)
•Long term damage to property
•Lost Tenants/Revenue

The Energy Efficiency of PIV
Solar Gain
Temperatures in the
loft space are on
average 3°C higher
than outside. By
delivering this warmer
air into the property
around 150 Watts per
day can be saved approximately 10% of
annual heating costs
Heat that
accumulates at
ceiling level is
redistributed
around the house.
This reduces space
heating costs
Humid air is displaced without
the need to open windows

INSULATION
VENTILATION
Filterless Extract Fan
Unique Patented helical expansion chamber
enables cyclone separation to occur, forcing
dust and contaminants away from the sealed
electric motor.

Your local Specialist ventilation Advisor
 Provides advice on the best method of
ventilation to improve indoor air quality and
reduce humidity levels.
 Assesses the problem and takes readings of
humidity levels
 Shows samples of the products and explains
how they work.
Therma-hygrometers are used to measure the
temperature, relative humidity and dew point in
a property. The levels will be higher in areas
suffering from condensation and mould.
