Noise protection of air heat pumps should be planned carefully
Internal insulation with mineral foam panels
The building materials industry classifies interior-insulation-systems increasingly as lucrative market. Here, the swing goes from impermeable material, to open to diffusion and capillary systems. The specially developed plates have the following basic pattern: lime, cement, sand and egg white proteins for frothing. The bulk density is low with values less than 100 kg/m3. This brings good insulation values. With the plates U-values from 0.5 to 0.4 W (m2K) can be achieved. When wall mounting the manufacturer’s instructions should be followed. Continue reading

When moisture damage the base heating is an alternative to internal insulation
Mold assessors know the problem. When steam condensate is reflected on the cold areas of a room and leads to an increased surface moisture, the wall structure has to be carefully examined. A classic thermal bridge occurs when the surface temperature at certain points of the wall is several degrees Celsius lower than the room air temperature. The first proposal for a fix will be in an improvement of the thermal insulation. Who would conceive, to avoid thermal bridges by a base heater? Continue reading

Create a healthy indoor climate
“Another article about healthy indoor climate”, some readers will think. The author finds it necessary to shed light on this important aspect of building and living in detail as a good indoor climate is often reduced to only heating and ventilation. But it must be observed even more aspects. The building- biology takes nature as a model. The aim of planning must be to produce as much as possible natural conditions in the interior.

Disastrous “low-budget” mold treatment
Recently made in the press a report circulating that many mold remediation are not conducted properly. “Three quarters of the architect, building surveyor, construction and renovation contractor and lawyers assume that 70 percent of the renovations are flawed,” reported the director of the Institute Peridomus Dr. Gerhard Führer from Himmelstadt/Germany. Even if there should be ten or twenty percent fewer cases, the incidence of improper renovations would be a disaster for the affected residents. So-called “brush renovations” mean nothing else than that the moisture damage was simply painted over. The new tenant sees the problem not at first attempt and the landlord has his first sleep.
