Health and solar warm air
in the industrialized countries.
For example it is estimated that 25% of
the Danish population will suffer from
allergy once in their lifetime.
Mould and dry rot thrive in moist conditions and can be harmful for furniture, buildings and people.
Unsound indoor climate in general may cause discomfort and add to the risk of disease.
Allergic reactions to unhealthy living conditions caused by mould and dry rot in our houses are numerous and increasing.
The need for venting and drying out our homes and other buildings peaks during winter and autumn periods when good venting habits involve high fuel bills.
A SolarVenti on the wall or the roof is a simple, low-cost and effective solution to the discomforts arising from an unsound indoor climate.
No operating costs, and a free heating supplement may be considered an extra bonus.
Radon is a radioactive, colourless, odorless, tasteless noble gas, occurring naturally as the decay product of radium, and is considered to be a health hazard due to its radioactivity.
Radon is responsible for the majority of the main public exposure to ionizing radiation.
It is often the single largest contributor to an individual's background radiation dose, and is the most variable from location to location.
Radon gas from natural sources can accumulate in buildings, especially in confined areas such as attics, and basements.
With a SolarVenti® ventilation system, 70-80% of radon gasses can be eliminated from your home.
For more information on radon gas, we recommend that you visit Public Health England's special site on radon gas called UKradon press this link:

UKradon has a map of UK radon prone areas, which you can see on this link:

We quite simply build and insulate our houses more and more to keep the expensive heat inside the building and forget that we thereby reduce the air flow and increase the air humidity. The simple solution to high air humidity has always been and still is proper airing. However, traditional venting through exterior doors, windows and air shafts involves loss of heat and heat costs money. More and more money as the energy resources of our planet becomes increasingly expensive to gain access to.
