Baufritz

Air quality

As one of Germany's first companies to produce off-site manufactured timber houses, Baufritz has focused intensively upon the idea of "healthy-living homes". Today all its homes are built entirely from bio-constructive, efficient and natural materials which radically affect the air quality within the home.

Therefore the right choice of materials is important to reduce the amount of toxic emissions in the building. Baufritz uses only natural products in all its houses to ensure the good health of its customers. Timber is not treated with hazardous chemicals and the component design is such that toxic adhesives, waxes, lacquers etc. need not be used. For example, the choice of insulation material very much determines the air quality in the building. Baufritz chooses not to use insulation material made from artificial mineral fibres, as these fibres are bound together by the use of a resin containing Formaldehyde, which can affect the air quality. Baufritz uses its own patented insulation material, Hoiz S45, an insulation material made from wood shavings, sprayed with whey and soda to make them fire, fungus and pesticide resistant. Hoiz S45 is a certified by European building authorities and Natureplus. Baufritz was also the first German homebuilder to build a house in accordance with guidelines from the Institute for the Environment and Health in Germany.

Good ventilation is also essential. Conventionally constructed buildings very often use materials that are non permeable, e.g. plastic membranes, which prevent the extraction of condensation created within the house. As a result these buildings very often suffer from high levels of humidity, mould and fungi and therefore a reduced air quality. Baufritz uses a permeable (breathable) wall construction that extracts condensation quicker than it is created. The construction therefore remains at the right moisture level which improves the durability and lifespan of the construction and guarantees the right air quality inside the house. Since dust-mites cannot survive below 55% humidity, this can help people who are allergic to dust.
