few weeks after the start of the heating season notice currently playing some house and apartment owners, or black goo black dust to the wall and Ceilings. The phenomenon has a name: fogging.
It is unclear how it leads to the formation of unsightly deposits. Ralf Holt, building biologist and pollution expert from Sassenberg has at least a suspicion: "It is estimated that there is renovation work on the interaction between construction and house dust." Laminate, vinyl foam wall coverings, PVC floor coverings and wall colors gases, plasticizers such as solvent or bonding agent, so Holt. Additionally, we are sometimes unfortunate circumstances such as tobacco smoke or the use of candles. Holt: "Even radiators and cold spots on the walls, so-called thermal bridges strengthen the problem. "
why the black dust is often found where old heaters available with high flow temperature or overnight storage devices. Unfortunately, the rapid cleaning is not that often simple: Because when you try to wipe off the pads, the parties must always recognize that the problem will only get worse. An incorrect use of building materials can cause the problem.
The building biologist familiar with the phenomenon from its expert practice: "There are people who use as interior paint exterior paint do not match, or combine building materials, their components. Since one can sometimes speak of happiness, if only arises fogging. " The phenomenon is annoying, but usually not harmful. One should only remove the donor materials again and use more advanced natural materials.
course should not be forgotten in today's tight construction, the usual proper ventilation in homes, the indoor air expert. By cross-ventilation of the apartment - at least three times a day - the humidity is reduced, which could prevent mold growth. It would also be the pollutant concentration in indoor air significantly reduced, which not only prevent fogging, but the overall health profitable.
In connection with fogging and contaminants in indoor air of the expert also pointed out that one in homes with carpeted floors should necessarily use the vacuum cleaner with a HEPA filter so that the pollutants are retained in the filters. For smooth surfaces, wet wipe is applied twice per week. At least if the house has a living with allergies.
Where appropriate, a home medical history and laboratory analysis of the black films help to narrow down the cause. Assistance to enable them to you in the Münsterland, the expert Holt offer under-www.baubiologie holtrup.de, Tel 02581-784635.
